Question 1

Design copies dandelion seeds' air-catching by a wide light tissue using tissue, string, tape, and scissors to slow the toy's fall. (correct answer)
Design copies burr hooks by sticky tape using tissue, string, tape, and scissors to make the toy stick to the ceiling.
Design copies spider silk strength by thick rope using tissue, string, tape, and scissors to hold a heavy backpack.
Design copies dandelion roots by digging down using tissue, string, tape, and scissors to help the toy land underground.

Explanation: This question assesses the skill 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs - specifically the designing solution that mimics nature part. Biomimicry design means copying nature's solutions to solve human problems; the process involves (1) identifying the human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism (how it works), (4) designing a human solution copying that mechanism with available materials, and (5) building and testing; the key is copying how it works, not just what it looks like, for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Chen's problem was his toy parachutes falling too fast; he looked at dandelion seeds which have fluffy tops that catch air to float slowly; the design uses tissue, string, tape, and scissors to make a wide parachute; the design mimics dandelion seeds by spreading out a light material like the fluffy tops; this copies the mechanism of air-catching that makes dandelion seeds float. The correct answer says 'Design copies dandelion seeds' air-catching by a wide light tissue using tissue, string, tape, and scissors to slow the toy's fall' which accurately describes the design's mimicry of nature; the answer shows understanding that the design copies the air-catching mechanism from dandelion seeds using wide tissue to solve Chen's problem of fast-falling toys; the mimicry is functional (copies how the shape catches air) not just visual (copies how it looks). A distractor like 'Design copies burr hooks by sticky tape using tissue, string, tape, and scissors to make the toy stick to the ceiling' is wrong because it copies the wrong plant part and mechanism, solving a different problem; students might choose this if they mix up materials or confuse which plant inspired the design. Help students design by following steps: (1) Problem: 'I need to...' (2) Nature: 'What animal/plant solves similar problem?' (3) Mechanism: 'HOW does the part work?' (be specific - 'water rolls off smooth surface'), (4) Materials: 'What can I use to copy that?' (5) Design: Make it! Emphasize copying the mechanism, not just looking like the animal: 'We are not making a duck costume, we are copying how feathers make water roll off.' Show before-after: Human problem → observe nature solution → copy mechanism → human solution works! Use graphic organizer: Problem [box] → Nature Inspiration [box] → How it works [box] → My design [box] → Materials [box]; let students practice full cycle with simple examples; watch for students who copy appearance without understanding function, or who cannot articulate specific mechanism being copied, or who think they need to use same materials as nature (e.g., real feathers) instead of materials with same property.

Question 2

Read about Chen's design. How does the design help Chen solve the problem? Chen's action figure crashes because the parachute falls fast. He copies dandelion seeds that catch air with fluffy tops. He used tissue paper, string, tape, scissors, and a toy. He made a wide tissue parachute and drew it floating down slowly.

Design copies dandelion seeds' air-catching by a wide tissue sheet using tissue, string, tape, and scissors to slow the figure down. (correct answer)
Design copies dandelion seeds' air-catching by a heavy rock using tissue, string, tape, and scissors to make the figure drop faster.
Design copies duck feathers' waterproofing by smooth plastic using tissue, string, tape, and scissors to keep the figure dry in rain.
Design copies burr hooks by hook strips using tissue, string, tape, and scissors to make the figure stick to your shirt.

Explanation: This question assesses the skill 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs - specifically the designing solution that mimics nature part. Biomimicry design means copying nature's solutions to solve human problems; the process involves (1) identifying the human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism (how it works), (4) designing a human solution copying that mechanism with available materials, and (5) building and testing; the key is copying how it works, not just what it looks like, for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Chen's problem was his action figure crashing from fast-falling parachutes; he looked at dandelion seeds which catch air with fluffy tops to fall slowly; the design uses tissue, string, tape, and scissors to make a wide parachute; the design mimics dandelion seeds by using a spread-out shape like the fluffy tops; this copies the mechanism of air-catching that makes dandelion seeds float slowly. The correct answer says 'Design copies dandelion seeds' air-catching by a wide tissue sheet using tissue, string, tape, and scissors to slow the figure down' which accurately describes how the design solves the problem; the answer shows understanding that the design copies the air-catching mechanism from dandelion seeds using wide tissue to solve Chen's problem of fast falls; the mimicry is functional (copies how it works) not just visual (copies how it looks). A distractor like 'Design copies dandelion seeds' air-catching by a heavy rock using tissue, string, tape, and scissors to make the figure drop faster' is wrong because it reverses the mechanism and solves the opposite problem; students might choose this if they do not understand the specific mechanism being copied or confuse the direction of inspiration. Help students design by following steps: (1) Problem: 'I need to...' (2) Nature: 'What animal/plant solves similar problem?' (3) Mechanism: 'HOW does the part work?' (be specific - 'water rolls off smooth surface'), (4) Materials: 'What can I use to copy that?' (5) Design: Make it! Emphasize copying the mechanism, not just looking like the animal: 'We are not making a duck costume, we are copying how feathers make water roll off.'

Question 3

Read about Sofia's design. What problem did the design solve? Sofia slips on smooth climbing holds. She copies gecko feet with tiny hairs for grip. She used work gloves, puffy paint, a stencil, and paper towels. She made tiny bumps on the gloves and drew the bumpy palms.

Design copies gecko feet's grip by adding tiny bumps using gloves and puffy paint to stop Sofia's hands from slipping. (correct answer)
Design copies gecko feet's grip by adding tiny bumps using gloves and puffy paint to help Sofia breathe underwater.
Design copies gecko feet's grip by adding tiny bumps using gloves and puffy paint to make her backpack waterproof.
Design copies gecko feet's grip by adding tiny bumps using gloves and puffy paint to help her parachute fall faster.

Explanation: This question assesses the skill 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs - specifically the designing solution that mimics nature part. Biomimicry design means copying nature's solutions to solve human problems; the process involves (1) identifying the human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism (how it works), (4) designing a human solution copying that mechanism with available materials, and (5) building and testing; the key is copying how it works, not just what it looks like, for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Sofia's problem was slipping on smooth climbing holds; she looked at gecko feet which have tiny hairs for grip; the design uses gloves and puffy paint to add tiny bumps; the design mimics gecko feet by creating bumpy texture like the hairs; this copies the mechanism of grip that makes gecko feet work. The correct answer says 'Design copies gecko feet's grip by adding tiny bumps using gloves and puffy paint to stop Sofia's hands from slipping' which accurately describes the problem solved; the answer shows understanding that the design copies the gripping mechanism from gecko feet using bumps to solve Sofia's problem of slipping hands; the mimicry is functional (copies how it works) not just visual (copies how it looks). A distractor like 'Design copies gecko feet's grip by adding tiny bumps using gloves and puffy paint to help Sofia breathe underwater' is wrong because it solves a different unrelated problem instead of slipping; students might choose this if they think biomimicry means becoming like the animal not copying specific function or confuse problems. Help students design by following steps: (1) Problem: 'I need to...' (2) Nature: 'What animal/plant solves similar problem?' (3) Mechanism: 'HOW does the part work?' (be specific - 'water rolls off smooth surface'), (4) Materials: 'What can I use to copy that?' (5) Design: Make it! Emphasize copying the mechanism, not just looking like the animal: 'We are not making a duck costume, we are copying how feathers make water roll off.'

Question 4

Read about Jamal's design. How does his design copy duck feathers? Jamal's backpack gets wet in rain. Duck feathers have a smooth coat that makes water roll off. Jamal made a backpack cover from a plastic sheet, tape, scissors, and elastic bands. He cut the plastic to fit, taped the edges, and added elastic to hold it on. The smooth plastic makes water bead and slide off like duck feathers. He drew a backpack with a plastic cover and raindrops sliding off.

Design copies duck feathers' waterproofing by a smooth plastic surface using plastic, tape, scissors, and elastic bands to keep books dry. (correct answer)
Design copies bird wings' flapping by bending plastic using plastic, tape, scissors, and elastic bands to help Jamal fly to school.
Design copies duck feet for swimming by adding web shapes using plastic, tape, scissors, and elastic bands to make the backpack float.
Design copies duck feathers' color by making it shiny using plastic, tape, scissors, and elastic bands to make the backpack look nicer.

Explanation: This question assesses the skill 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs - specifically the designing solution that mimics nature part. Biomimicry design means copying nature's solutions to solve human problems; the process involves (1) identifying the human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism (how it works), (4) designing a human solution copying that mechanism with available materials, and (5) building and testing; the key is copying how it works, not just what it looks like, for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Jamal's problem was keeping his backpack dry in the rain; he looked at duck feathers which have a smooth coat that makes water roll off; the design uses plastic sheet, tape, scissors, and elastic bands to make a fitted cover; the design mimics duck feathers by creating a smooth surface like the feathers; this copies the mechanism of water beading and sliding off that makes duck feathers waterproof. The correct answer says 'Design copies duck feathers' waterproofing by a smooth plastic surface using plastic, tape, scissors, and elastic bands to keep books dry' which accurately describes the design's mimicry of nature; the answer shows understanding that the design copies the waterproofing mechanism from duck feathers using smooth plastic to solve Jamal's problem of a wet backpack; the mimicry is functional (copies how the smooth surface repels water) not just visual (copies how it looks). A distractor like 'Design copies bird wings' flapping by bending plastic using plastic, tape, scissors, and elastic bands to help Jamal fly to school' is wrong because it claims to copy the wrong animal part and mechanism, solving a different impossible problem instead of waterproofing; students might choose this if they confuse which animal inspired the design or focus on appearance not mechanism. Help students design by following steps: (1) Problem: 'I need to...' (2) Nature: 'What animal/plant solves similar problem?' (3) Mechanism: 'HOW does the part work?' (be specific - 'water rolls off smooth surface'), (4) Materials: 'What can I use to copy that?' (5) Design: Make it!

Question 5

Read about Carlos's design. How does Carlos's design copy an elephant trunk? Carlos cannot reach a ball behind the washer. An elephant trunk is long and can grab things. Carlos used a ruler, string, a binder clip, and tape. He taped the clip on, tied string, and pulled to close the clip. He drew the ruler-trunk reaching the ball.

Design copies elephant trunk by long reach and pinch grip using ruler, binder clip, string, and tape to grab the ball in tight space. (correct answer)
Design copies elephant trunk by spraying water using ruler, binder clip, string, and tape to wash the floor behind the washer.
Design copies gecko feet by sticky hairs using ruler, binder clip, string, and tape to climb up the washing machine.
Design copies bird wings by flapping using ruler, binder clip, string, and tape to make the ball fly out by itself.

Explanation: This question assesses the skill 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs - specifically the designing solution that mimics nature part. Biomimicry design means copying nature's solutions to solve human problems; the process involves (1) identifying the human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism (how it works), (4) designing a human solution copying that mechanism with available materials, and (5) building and testing; the key is copying how it works, not just what it looks like, for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Carlos's problem was not being able to reach a ball behind the washer; he looked at an elephant trunk which is long and can grab; the design uses ruler, binder clip, string, and tape to make a long grabber; the design mimics the elephant trunk by long reach and pinch grip; this copies the mechanism of extension and grasping that makes the elephant trunk work. The correct answer says 'Design copies elephant trunk by long reach and pinch grip using ruler, binder clip, string, and tape to grab the ball in tight space' which accurately describes the design's mimicry of nature; the answer shows understanding that the design copies the reaching and gripping mechanism from the elephant trunk using tools to solve Carlos's problem of inaccessibility; the mimicry is functional (copies how it works) not just visual (copies how it looks). A distractor like 'Design copies elephant trunk by spraying water using ruler, binder clip, string, and tape to wash the floor behind the washer' is wrong because it identifies the wrong mechanism and solves a different problem; students might choose this if they confuse the specific feature being copied or think biomimicry includes unrelated animal abilities. Help students design by following steps: (1) Problem: 'I need to...' (2) Nature: 'What animal/plant solves similar problem?' (3) Mechanism: 'HOW does the part work?' (be specific - 'water rolls off smooth surface'), (4) Materials: 'What can I use to copy that?' (5) Design: Make it! Emphasize copying the mechanism, not just looking like the animal: 'We are not making a duck costume, we are copying how feathers make water roll off.'

Question 6

Read about Emma's design. Why did Emma copy burr seeds? Emma's little sister cannot tie shoes. Burr seeds have tiny hooks that grab loops on fur and cloth. Emma used Velcro strips, scissors, fabric glue, and old shoes. She cut Velcro, glued hook side on one strap, glued loop side on the other, and pressed them together. She drew a shoe strap with hook-and-loop pieces.

Design copies burr hooks by hooks grabbing loops using Velcro, scissors, and glue to make shoes close without tying laces. (correct answer)
Design copies duck feathers by smooth plastic using Velcro, scissors, and glue to keep shoes dry in puddles.
Design copies burr seeds by making them round using Velcro, scissors, and glue to help shoes roll down the hall.
Design copies bird beaks by snapping shut using Velcro, scissors, and glue to help shoes chirp when walking.

Explanation: This question assesses the skill 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs - specifically the designing solution that mimics nature part. Biomimicry design means copying nature's solutions to solve human problems; the process involves (1) identifying the human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism (how it works), (4) designing a human solution copying that mechanism with available materials, and (5) building and testing; the key is copying how it works, not just what it looks like, for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Emma's problem was her little sister unable to tie shoes; she looked at burr seeds which have tiny hooks that grab loops on fur and cloth; the design uses Velcro, scissors, and glue to make fastening straps; the design mimics burr seeds by using hooks grabbing loops like the burr hooks; this copies the mechanism of hooking that makes burr seeds stick. The correct answer says 'Design copies burr hooks by hooks grabbing loops using Velcro, scissors, and glue to make shoes close without tying laces' which accurately describes the design's mimicry of nature; the answer shows understanding that the design copies the hooking mechanism from burr seeds using Velcro to solve Emma's problem of untied shoes; the mimicry is functional (copies how the hooks grab) not just visual (copies how it looks). A distractor like 'Design copies duck feathers by smooth plastic using Velcro, scissors, and glue to keep shoes dry in puddles' is wrong because it copies the wrong nature inspiration and mechanism, solving a different problem; students might choose this if they confuse which plant or animal inspired the design or focus on appearance not mechanism. Help students design by following steps: (1) Problem: 'I need to...' (2) Nature: 'What animal/plant solves similar problem?' (3) Mechanism: 'HOW does the part work?' (be specific - 'water rolls off smooth surface'), (4) Materials: 'What can I use to copy that?' (5) Design: Make it! Emphasize copying the mechanism, not just looking like the animal: 'We are not making a duck costume, we are copying how feathers make water roll off.'

Question 7

Look at the design Sofia made. Her hands slipped on smooth climbing holds. She copied gecko feet and made grippy gloves using work gloves, puffy paint, a stencil, and scissors. How does the design work like gecko feet?

Design copies gecko feet's tiny hairs by making small puffy bumps on gloves to grip smooth holds and stop slipping. (correct answer)
Design copies gecko tails by making long strings on gloves to balance better and jump higher on rocks.
Design copies duck feathers by using plastic sheets on gloves so water rolls off during climbing practice.
Design copies gecko color change by painting gloves green so the holds feel rougher and hands never slip.

Explanation: This question assesses the skill from 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs, focusing on designing solutions that mimic nature. Biomimicry design means copying nature's solutions to solve human problems. The process involves: (1) identifying a human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism or how it works, (4) designing a human solution that copies that mechanism with available materials, and (5) building and testing it. The key is copying how it works, not just what it looks like; for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Sofia's problem was her hands slipping on smooth climbing holds; she looked at gecko feet which have tiny hairs that create a sticky grip to climb smooth surfaces. The design uses work gloves, puffy paint, a stencil, and scissors to make grippy gloves. The design mimics gecko feet by adding small puffy bumps like tiny hairs to grip smooth holds. This copies the mechanism of microscopic hairs providing adhesion that makes gecko feet sticky. The correct answer says 'Design copies gecko feet's tiny hairs by making small puffy bumps on gloves to grip smooth holds and stop slipping' which accurately describes the design's mimicry of nature using bumps to copy the gripping mechanism. The answer shows understanding that the design copies the adhesion mechanism from gecko feet using puffy paint materials to solve Sofia's problem of slipping hands, with the mimicry being functional by copying how the hairs grip rather than just visual appearance. A distractor like 'Design copies gecko tails by making long strings on gloves to balance better and jump higher on rocks' is wrong because it claims the design copies the wrong animal part and describes an unrelated mechanism for balance instead of grip. Students might choose this if they confuse which animal part was inspired or do not understand the specific gripping feature being copied, thinking biomimicry means copying any part of the animal. Help students design by following steps: (1) Problem: 'I need to grip smooth holds,' (2) Nature: 'What animal climbs smooth surfaces? Geckos with feet,' (3) Mechanism: 'How does it work? Tiny hairs create sticky grip,' (4) Materials: 'What can I use to copy that? Puffy paint for bumps,' (5) Design: Make it! Emphasize copying the mechanism, not just looking like a gecko; 'We are not making gecko costumes, we are copying how feet grip.' Show before-after: Human problem of slipping → observe gecko feet's solution → copy gripping mechanism → hands don't slip! Use a graphic organizer: Problem [box] → Nature Inspiration [box] → How it works [box] → My design [box] → Materials [box]. Let students practice the full cycle with simple examples like this. Watch for students who copy appearance without understanding function, or who cannot articulate the specific mechanism being copied, or who think they need to use real hairs instead of materials with similar properties.

Question 8

Read about Chen's design. His toy parachutes fell too fast. He copied dandelion seeds and made a parachute using tissue paper, string, tape, scissors, and a small toy. What problem does the design solve?

Design copies dandelion fluff by using light tissue to catch air, helping the toy fall slowly instead of crashing fast. (correct answer)
Design copies burr hooks by using Velcro to stick shoes closed, helping Chen tie laces without knots.
Design copies elephant trunks by using a ruler tool to reach behind washers, helping Chen grab a ball far away.
Design copies duck feathers by using a plastic cover, helping Chen keep his lunch warm and dry all day.

Explanation: This question assesses the skill from 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs, focusing on designing solutions that mimic nature. Biomimicry design means copying nature's solutions to solve human problems. The process involves: (1) identifying a human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism or how it works, (4) designing a human solution that copies that mechanism with available materials, and (5) building and testing it. The key is copying how it works, not just what it looks like; for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Chen's problem was his toy parachutes falling too fast and crashing; he looked at dandelion seeds which have fluffy parachutes that catch air to float slowly and spread far. The design uses tissue paper, string, tape, scissors, and a small toy to make a parachute. The design mimics dandelion fluff by using light, spread-out tissue to catch air and slow the fall. This copies the mechanism of a parachute-like structure increasing air resistance that makes dandelion seeds float gently. The correct answer says 'Design copies dandelion fluff by using light tissue to catch air, helping the toy fall slowly instead of crashing fast' which accurately describes the design's mimicry of nature to solve the problem of fast-falling toys. The answer shows understanding that the design copies the air-catching mechanism from dandelion seeds using tissue materials to solve Chen's problem of crashing toys, with the mimicry being functional by copying how it floats rather than just visual appearance. A distractor like 'Design copies burr hooks by using Velcro to stick shoes closed, helping Chen tie laces without knots' is wrong because it identifies the wrong plant inspiration and solves a different problem unrelated to falling speed. Students might choose this if they mix up materials or problems, or confuse which plant was copied without understanding the specific floating mechanism. Help students design by following steps: (1) Problem: 'I need to slow falling,' (2) Nature: 'What plant floats slowly? Dandelions with fluff,' (3) Mechanism: 'How does it work? Fluff catches air like a parachute,' (4) Materials: 'What can I use to copy that? Light tissue,' (5) Design: Make it! Emphasize copying the mechanism, not just looking like a dandelion; 'We are not making flower costumes, we are copying how fluff slows descent.' Show before-after: Human problem of fast fall → observe dandelion's solution → copy air-catching mechanism → toy falls slowly! Use a graphic organizer: Problem [box] → Nature Inspiration [box] → How it works [box] → My design [box] → Materials [box]. Let students practice the full cycle with simple examples like this. Watch for students who copy appearance without understanding function, or who cannot articulate the specific mechanism being copied, or who think they need to use real fluff instead of materials with similar lightness.

Question 9

Read about Carlos's design. He dropped a ball behind the washing machine. He copied an elephant trunk and made a long grabber using a ruler, string, a binder clip, and tape. How does the design help Carlos solve the problem?

Design copies an elephant trunk's long reach and grip by using a ruler and binder clip to grab the ball in a tight space. (correct answer)
Design copies an elephant ear's flapping by using paper fans to blow the ball out from behind the washer.
Design copies spider silk by using fishing line to hang the ball from the ceiling so it cannot roll away.
Design copies duck feathers by using wax paper to make the ball waterproof so it rolls out by itself.

Explanation: This question assesses the skill from 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs, focusing on designing solutions that mimic nature. Biomimicry design means copying nature's solutions to solve human problems. The process involves: (1) identifying a human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism or how it works, (4) designing a human solution that copies that mechanism with available materials, and (5) building and testing it. The key is copying how it works, not just what it looks like; for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Carlos's problem was reaching a ball dropped behind the washing machine in a tight space; he looked at an elephant trunk which is long and flexible with a gripping end to reach and grab distant objects. The design uses a ruler, string, a binder clip, and tape to make a long grabber. The design mimics the elephant trunk by extending reach with the ruler and gripping with the clip. This copies the mechanism of length and controllable grip that makes the trunk effective for reaching. The correct answer says 'Design copies an elephant trunk's long reach and grip by using a ruler and binder clip to grab the ball in a tight space' which accurately describes the design's mimicry of nature to solve the reaching problem. The answer shows understanding that the design copies the reach and grip mechanism from the elephant trunk using ruler and clip materials to solve Carlos's problem of inaccessible ball, with the mimicry being functional by copying how it extends and grabs rather than just visual appearance. A distractor like 'Design copies an elephant ear's flapping by using paper fans to blow the ball out from behind the washer' is wrong because it copies the wrong animal part and describes a blowing mechanism instead of reaching. Students might choose this if they confuse which animal part was inspired or do not understand the specific reaching feature, thinking biomimicry means copying any elephant action. Help students design by following steps: (1) Problem: 'I need to reach far,' (2) Nature: 'What animal reaches far? Elephants with trunks,' (3) Mechanism: 'How does it work? Long flexible tube with grip,' (4) Materials: 'What can I use to copy that? Ruler and clip,' (5) Design: Make it! Emphasize copying the mechanism, not just looking like an elephant; 'We are not making trunk costumes, we are copying how trunks reach and grab.' Show before-after: Human problem of unreachable ball → observe trunk's solution → copy reaching mechanism → ball is grabbed! Use a graphic organizer: Problem [box] → Nature Inspiration [box] → How it works [box] → My design [box] → Materials [box]. Let students practice the full cycle with simple examples like this. Watch for students who copy appearance without understanding function, or who cannot articulate the specific mechanism being copied, or who think they need to use real trunks instead of materials with similar extension.

Question 10

Look at the design Maya made. Her mobile string kept breaking. She copied spider silk and used fishing line, scissors, objects to hang, and a hanger. What part of nature inspired Maya's design?

Design copies spider silk's strong thin fibers by using fishing line to hold hanging objects without breaking in her mobile. (correct answer)
Design copies gecko feet's tiny hairs by using puffy paint so the mobile sticks to walls and never falls down.
Design copies duck feathers' smooth coating by using plastic so the mobile stays dry in the rain outside.
Design copies dandelion fluff by using tissue paper so the mobile floats away in the wind safely.

Explanation: This question assesses the skill from 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs, focusing on designing solutions that mimic nature. Biomimicry design means copying nature's solutions to solve human problems. The process involves: (1) identifying a human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism or how it works, (4) designing a human solution that copies that mechanism with available materials, and (5) building and testing it. The key is copying how it works, not just what it looks like; for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Maya's problem was her mobile string breaking under the weight of hanging objects; she looked at spider silk which is strong and thin to support webs and capture prey without snapping. The design uses fishing line, scissors, objects to hang, and a hanger to make a sturdy mobile. The design mimics spider silk by using strong, thin fishing line to hold weight. This copies the mechanism of high tensile strength in thin fibers that makes spider silk durable. The correct answer says 'Design copies spider silk's strong thin fibers by using fishing line to hold hanging objects without breaking in her mobile' which accurately describes the design's mimicry of nature to solve the breaking problem. The answer shows understanding that the design copies the strength mechanism from spider silk using fishing line materials to solve Maya's problem of weak strings, with the mimicry being functional by copying how it supports weight rather than just visual appearance. A distractor like 'Design copies gecko feet's tiny hairs by using puffy paint so the mobile sticks to walls and never falls down' is wrong because it copies the wrong animal part and solves a different problem of sticking instead of strength. Students might choose this if they mix up inspirations or confuse mechanisms, thinking biomimicry means making things sticky instead of strong. Help students design by following steps: (1) Problem: 'I need strong string,' (2) Nature: 'What animal makes strong threads? Spiders with silk,' (3) Mechanism: 'How does it work? Thin but strong fibers,' (4) Materials: 'What can I use to copy that? Fishing line,' (5) Design: Make it! Emphasize copying the mechanism, not just looking like a spider; 'We are not making web costumes, we are copying how silk holds weight.' Show before-after: Human problem of breaking string → observe silk's solution → copy strength mechanism → mobile hangs securely! Use a graphic organizer: Problem [box] → Nature Inspiration [box] → How it works [box] → My design [box] → Materials [box]. Let students practice the full cycle with simple examples like this. Watch for students who copy appearance without understanding function, or who cannot articulate the specific mechanism being copied, or who think they need to use real silk instead of materials with similar strength.

Question 11

Read about Jamal's design. What materials did Jamal use? Jamal needs to keep rain off his backpack. He copies duck feathers that make water roll off. He made a cover by cutting a plastic sheet, taping edges, and adding elastic bands. He drew raindrops sliding off the smooth cover.

Design copies duck feathers' waterproofing using plastic sheet, tape, scissors, and elastic bands to keep rain off the backpack. (correct answer)
Design copies duck feathers' waterproofing using paper towels, glue, crayons, and yarn to keep rain off the backpack.
Design copies duck feathers' waterproofing using batteries, wire, metal clips, and lights to keep rain off the backpack.
Design copies duck feathers' waterproofing using clay, sand, sticks, and leaves to keep rain off the backpack.

Explanation: This question assesses the skill 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs - specifically the designing solution that mimics nature part. Biomimicry design means copying nature's solutions to solve human problems; the process involves (1) identifying the human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism (how it works), (4) designing a human solution copying that mechanism with available materials, and (5) building and testing; the key is copying how it works, not just what it looks like, for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Jamal's problem was keeping rain off his backpack; he looked at duck feathers which make water roll off with their smooth coat; the design uses plastic sheet, tape, scissors, and elastic bands to make a waterproof cover; the design mimics duck feathers by using smooth plastic; this copies the mechanism of water sliding off that makes duck feathers waterproof. The correct answer says 'Design copies duck feathers' waterproofing using plastic sheet, tape, scissors, and elastic bands to keep rain off the backpack' which accurately describes the materials used; the answer shows understanding that the design copies the waterproofing mechanism from duck feathers using specific materials to solve Jamal's problem of a wet backpack; the mimicry is functional (copies how it works) not just visual (copies how it looks). A distractor like 'Design copies duck feathers' waterproofing using paper towels, glue, crayons, and yarn to keep rain off the backpack' is wrong because it lists wrong materials that wouldn't mimic the smooth waterproofing; students might choose this if they cannot articulate how the mechanism is copied or mix up materials. Help students design by following steps: (1) Problem: 'I need to...' (2) Nature: 'What animal/plant solves similar problem?' (3) Mechanism: 'HOW does the part work?' (be specific - 'water rolls off smooth surface'), (4) Materials: 'What can I use to copy that?' (5) Design: Make it!

Question 12

Read about Maya's design. What part of nature inspired Maya's design? Maya's mobile string keeps breaking. Spider silk is thin but very strong. Maya used fishing line, scissors, a hanger, and small objects to hang. She cut fishing line, tied objects on, and hung them up. She drew a hanger with strings holding objects.

Design copies spider silk strength by using thin strong fishing line with scissors and a hanger to hold the mobile without breaking. (correct answer)

Design copies duck feathers by using plastic with scissors and a hanger to make the mobile waterproof in rain.
Design copies gecko feet by using puffy paint with scissors and a hanger to make the mobile stick to the wall.

Maya's problem was her mobile strings breaking under weight; she looked at spider silk which is thin but very strong; the design uses fishing line, scissors, and a hanger to make durable hanging strings; the design mimics spider silk by using thin strong line like the silk; this copies the mechanism of strength in thin material that makes spider silk work. The correct answer says 'Design copies spider silk strength by using thin strong fishing line with scissors and a hanger to hold the mobile without breaking' which accurately describes the design's mimicry of nature; the answer shows understanding that the design copies the strength mechanism from spider silk using fishing line to solve Maya's problem of breaking strings; the mimicry is functional (copies how the thin material holds weight) not just visual (copies how it looks). A distractor like 'Design copies dandelion fluff by using tissue paper with scissors and a hanger to make the mobile float away in wind' is wrong because it copies the wrong nature inspiration and mechanism, solving a different problem; students might choose this if they mix up which animal inspired the design or focus on appearance not function. Help students design by following steps: (1) Problem: 'I need to...' (2) Nature: 'What animal/plant solves similar problem?' (3) Mechanism: 'HOW does the part work?' (be specific - 'water rolls off smooth surface'), (4) Materials: 'What can I use to copy that?' (5) Design: Make it!

Question 13

Read about Sofia's design. How does the design work like gecko feet? Sofia's hands slip on smooth climbing holds. Gecko feet have tiny hairs that grip. Sofia used work gloves, puffy paint, a stencil, and paper towels. She painted tiny bumps on the palms and fingers and let them dry. She drew gloves with lots of little bumps on them.

Design copies gecko feet's grip by tiny bumps using gloves, puffy paint, and a stencil to help hands not slip on holds. (correct answer)
Design copies gecko feet's color change by bright paint using gloves, puffy paint, and a stencil to help Sofia hide on rocks.
Design copies duck feathers' waterproofing by smooth paint using gloves, puffy paint, and a stencil to keep Sofia's hands dry.
Design copies gecko tails for balance by long strings using gloves, puffy paint, and a stencil to help Sofia swing safely.

Sofia's problem was her hands slipping on smooth climbing holds; she looked at gecko feet which have tiny hairs that grip surfaces; the design uses gloves, puffy paint, and a stencil to make textured palms; the design mimics gecko feet by adding tiny bumps like the hairs; this copies the mechanism of increased grip through bumpy texture that makes gecko feet work. The correct answer says 'Design copies gecko feet's grip by tiny bumps using gloves, puffy paint, and a stencil to help hands not slip on holds' which accurately describes the design's mimicry of nature; the answer shows understanding that the design copies the gripping mechanism from gecko feet using bumpy paint to solve Sofia's problem of slipping hands; the mimicry is functional (copies how the tiny structures create grip) not just visual (copies how it looks). A distractor like 'Design copies gecko feet's color change by bright paint using gloves, puffy paint, and a stencil to help Sofia hide on rocks' is wrong because it identifies the wrong mechanism and solves a different problem unrelated to grip; students might choose this if they do not understand the specific feature being copied or confuse gecko abilities. Help students design by following steps: (1) Problem: 'I need to...' (2) Nature: 'What animal/plant solves similar problem?' (3) Mechanism: 'HOW does the part work?'

Question 14

Read about Carlos's design. How does the design help Carlos solve the problem? Carlos dropped a ball behind the washing machine. An elephant trunk is long and can grab. Carlos used a ruler, string, a binder clip, and tape. He taped the clip to the ruler, tied string to the clip handles, slid it in, and pulled string to grab the ball. He drew a long ruler with a clip grabbing a ball.

Design copies elephant trunk reach and grip by a long ruler and clip using ruler, string, tape, and binder clip to grab the ball. (correct answer)
Design copies elephant ears by flapping wide paper using ruler, string, tape, and binder clip to cool the washing machine.
Design copies spider silk by making a web using ruler, string, tape, and binder clip to catch flies in the laundry room.
Design copies fish fins by swimming fast using ruler, string, tape, and binder clip to push the washing machine away.

Explanation: This question assesses the skill 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs - specifically the designing solution that mimics nature part. Biomimicry design means copying nature's solutions to solve human problems; the process involves (1) identifying the human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism (how it works), (4) designing a human solution copying that mechanism with available materials, and (5) building and testing; the key is copying how it works, not just what it looks like, for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Carlos's problem was reaching a ball behind the washing machine; he looked at an elephant trunk which is long and can grab things; the design uses ruler, string, tape, and binder clip to make an extendable grabber; the design mimics the elephant trunk by extending reach with a long tool and gripping with a clip; this copies the mechanism of long reach and grip that makes the elephant trunk work. The correct answer says 'Design copies elephant trunk reach and grip by a long ruler and clip using ruler, string, tape, and binder clip to grab the ball' which accurately describes the design's mimicry of nature; the answer shows understanding that the design copies the reaching and gripping mechanism from the elephant trunk using a ruler and clip to solve Carlos's problem of inaccessible items; the mimicry is functional (copies how the trunk extends and grabs) not just visual (copies how it looks). A distractor like 'Design copies elephant ears by flapping wide paper using ruler, string, tape, and binder clip to cool the washing machine' is wrong because it copies the wrong animal part and mechanism, solving an unrelated problem; students might choose this if they confuse which animal part is being copied or do not understand the specific function. Help students design by following steps: (1) Problem: 'I need to...' (2) Nature: 'What animal/plant solves similar problem?' (3) Mechanism: 'HOW does the part work?'

Question 15

Look at the design Chen made. He cut tissue paper, taped strings, and tied a toy under it. He copied a dandelion seed. How does Chen's design copy the dandelion seed?

Design copies dandelion fluff catching air by using wide, light tissue paper and strings to slow the toy's fall. (correct answer)
Design copies dandelion roots by using thick sticks and rocks to hold the toy down so it drops faster.
Design copies burr hooks by using Velcro to stick the toy to the ceiling so it never falls.
Design copies duck feathers by using plastic so the toy swims better and lands safely in water.

Explanation: This question assesses the skill from 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs, focusing on designing solutions that mimic nature. Biomimicry design means copying nature's solutions to solve human problems. The process involves: (1) identifying a human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism or how it works, (4) designing a human solution that copies that mechanism with available materials, and (5) building and testing it. The key is copying how it works, not just what it looks like; for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Chen's problem was making a toy fall slowly instead of crashing; he looked at dandelion seeds which have fluffy structures that catch air to descend gently. The design uses tissue paper cut wide, taped with strings, and tied to a toy to make a parachute. The design mimics dandelion fluff by spreading out light tissue to increase air resistance. This copies the mechanism of parachute-like fluff slowing descent that makes dandelion seeds effective. The correct answer says 'Design copies dandelion fluff catching air by using wide, light tissue paper and strings to slow the toy's fall' which accurately describes how the design mimics the plant's mechanism. The answer shows understanding that the design copies the air-catching mechanism from dandelion seeds using tissue and strings to solve Chen's problem of fast falls, with the mimicry being functional by copying how it floats. A distractor like 'Design copies dandelion roots by using thick sticks and rocks to hold the toy down so it drops faster' is wrong because it copies the wrong plant part and reverses the goal by making it fall faster instead of slower. Students might choose this if they confuse plant parts or do not understand the direction of inspiration for slowing descent. Help students design by following steps: (1) Problem: 'I need slow falling,' (2) Nature: 'What plant falls slowly? Dandelions with fluff,' (3) Mechanism: 'How does it work? Fluff catches air,' (4) Materials: 'What can I use to copy that? Tissue and strings,' (5) Design: Make it! Emphasize copying the mechanism, not just looking like a dandelion; 'We are not making seed costumes, we are copying how fluff catches air.' Show before-after: Human problem of crashing → observe dandelion's solution → copy mechanism → gentle landing! Use a graphic organizer: Problem [box] → Nature Inspiration [box] → How it works [box] → My design [box] → Materials [box]. Let students practice the full cycle with simple examples like this. Watch for students who copy appearance without understanding function, or who cannot articulate the specific mechanism being copied, or who think biomimicry means speeding up instead of mimicking the natural slow descent.

Question 16

Design copies gecko feet's tiny hairs by making small puffy bumps on gloves to grip smooth holds and stop slipping. (correct answer)
Design copies gecko tails by making long strings on gloves to balance better and jump higher on rocks.
Design copies duck feathers by using plastic sheets on gloves so water rolls off during climbing practice.
Design copies gecko color change by painting gloves green so the holds feel rougher and hands never slip.

Question 17

Read about Sofia's design. What part of nature inspired it?

Design copies gecko feet using bumpy paint on gloves, so the hands grip smooth holds and do not slip. (correct answer)
Design copies duck feathers using plastic, so the gloves stay dry when Sofia climbs in the rain.
Design copies elephant trunk using a ruler, so Sofia can reach higher holds without climbing.
Design copies burr seeds using Velcro, so Sofia's gloves stick together when she claps her hands.

Explanation: This question tests understanding of designing biomimicry solutions (1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs - designing solution that mimics nature part). Biomimicry design means copying nature's solutions to solve human problems. Process: (1) Identify human problem, (2) Find animal/plant with similar need and observe how external part solves it, (3) Figure out the MECHANISM (how it works), (4) Design human solution copying that mechanism with available materials, (5) Build and test. The key is copying HOW it works (mechanism), not just what it looks like. Sofia's problem was gripping smooth climbing holds without slipping. Sofia looked at geckos which have feet with tiny bumps that grip smooth surfaces. The design uses bumpy paint on gloves to create texture. The design mimics gecko feet by having bumpy texture that increases friction. This copies the gripping mechanism that makes gecko feet work. The correct answer says "Design copies gecko feet using bumpy paint on gloves, so the hands grip smooth holds and do not slip" which accurately identifies the nature inspiration as gecko feet. The answer shows understanding that the design copies the bumpy texture from gecko feet using textured paint to solve Sofia's problem of gripping. The mimicry is functional (copies how it works) not just visual (copies how it looks). Wrong answers like "Design copies duck feathers using plastic, so the gloves stay dry when Sofia climbs in the rain" are wrong because they identify the wrong nature inspiration - the problem is gripping not staying dry, and the solution uses bumpy texture not smooth waterproofing. Students might choose this if they confuse different biomimicry examples or don't match the solution to the actual problem. Help students design by following steps: (1) Problem: "I need to..." (2) Nature: "What animal/plant solves similar problem?" (3) Mechanism: "HOW does the part work?" (be specific), (4) Materials: "What can I use to copy that?" (5) Design: Make it! Watch for: students who copy appearance without understanding function, or who cannot articulate specific mechanism being copied.

Question 18

Design copies dandelion fluff by using light tissue to catch air, helping the toy fall slowly instead of crashing fast. (correct answer)
Design copies burr hooks by using Velcro to stick shoes closed, helping Chen tie laces without knots.
Design copies elephant trunks by using a ruler tool to reach behind washers, helping Chen grab a ball far away.
Design copies duck feathers by using a plastic cover, helping Chen keep his lunch warm and dry all day.

Explanation: This question assesses the skill from 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs, focusing on designing solutions that mimic nature. Biomimicry design means copying nature's solutions to solve human problems. The process involves: (1) identifying a human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism or how it works, (4) designing a human solution that copies that mechanism with available materials, and (5) building and testing it. The key is copying how it works, not just what it looks like; for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Chen's problem was his toy parachutes falling too fast and crashing; he looked at dandelion seeds which have fluffy parachutes that catch air to float slowly and spread far. The design uses tissue paper, string, tape, scissors, and a small toy to make a parachute. The design mimics dandelion fluff by using light, spread-out tissue to catch air and slow the fall. This copies the mechanism of a parachute-like structure increasing air resistance that makes dandelion seeds float gently. The correct answer says 'Design copies dandelion fluff by using light tissue to catch air, helping the toy fall slowly instead of crashing fast' which accurately describes the design's mimicry of nature to solve the problem of fast-falling toys. The answer shows understanding that the design copies the air-catching mechanism from dandelion seeds using tissue materials to solve Chen's problem of crashing toys, with the mimicry being functional by copying how it floats rather than just visual appearance. A distractor like 'Design copies burr hooks by using Velcro to stick shoes closed, helping Chen tie laces without knots' is wrong because it identifies the wrong plant inspiration and solves a different problem unrelated to falling speed. Students might choose this if they mix up materials or problems, or confuse which plant was copied without understanding the specific floating mechanism. Help students design by following steps: (1) Problem: 'I need to slow falling,' (2) Nature: 'What plant floats slowly? Dandelions with fluff,' (3) Mechanism: 'How does it work? Fluff catches air like a parachute,' (4) Materials: 'What can I use to copy that? Light tissue,' (5) Design: Make it! Emphasize copying the mechanism, not just looking like a dandelion; 'We are not making flower costumes, we are copying how fluff slows descent.'

Use a graphic organizer: Problem [box] → Nature Inspiration [box] → How it works [box] → My design [box] → Materials [box]. Let students practice the full cycle with simple examples like this. Watch for students who copy appearance without understanding function, or who cannot articulate the specific mechanism being copied, or who think they need to use real fluff instead of materials with similar lightness.

Question 19

Read about Jamal's design. His books got wet in rain. He copied duck feathers and made a backpack cover using a plastic sheet, scissors, tape, and elastic bands. How does Jamal's design copy duck feathers?

Design copies duck feathers' waterproof smooth coat by using a smooth plastic cover and tape to keep rain off books. (correct answer)
Design copies duck feet for swimming by using elastic bands to help Jamal swim to school in rain.
Design copies gecko feet's tiny hairs by using chalk and bumps to stick to walls and climb faster.
Design copies duck feathers' colors by using markers and paint to look like a duck and stop rain.

Explanation: This question assesses the skill from 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs, focusing on designing solutions that mimic nature. Biomimicry design means copying nature's solutions to solve human problems. The process involves: (1) identifying a human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism or how it works, (4) designing a human solution that copies that mechanism with available materials, and (5) building and testing it. The key is copying how it works, not just what it looks like; for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Jamal's problem was his books getting wet in the rain; he looked at duck feathers which have a smooth, oily coating that makes water roll off to keep the duck dry. The design uses a plastic sheet, scissors, tape, and elastic bands to make a backpack cover. The design mimics duck feathers by using smooth plastic to make water roll off the books. This copies the mechanism of a smooth surface repelling water that makes duck feathers waterproof. The correct answer says 'Design copies duck feathers' waterproof smooth coat by using a smooth plastic cover and tape to keep rain off books' which accurately describes the design's mimicry of nature using smooth plastic to repel water like feathers. The answer shows understanding that the design copies the waterproof mechanism from duck feathers using plastic materials to solve Jamal's problem of wet books, with the mimicry being functional by copying how water rolls off rather than just visual appearance. A distractor like 'Design copies duck feet for swimming by using elastic bands to help Jamal swim to school in rain' is wrong because it claims the design copies the wrong animal part and solves a different problem unrelated to keeping books dry. Students might choose this if they confuse which animal part was inspired or focus on appearance like webbed feet without understanding the specific waterproof mechanism being copied. Help students design by following steps: (1) Problem: 'I need to keep books dry,' (2) Nature: 'What animal stays dry in water? Ducks with feathers,' (3) Mechanism: 'How does it work? Smooth surface makes water roll off,' (4) Materials: 'What can I use to copy that? Smooth plastic,' (5) Design: Make it! Emphasize copying the mechanism, not just looking like a duck; 'We are not making a duck costume, we are copying how feathers make water roll off.'

Use a graphic organizer: Problem [box] → Nature Inspiration [box] → How it works [box] → My design [box] → Materials [box]. Let students practice the full cycle with simple examples like this. Watch for students who copy appearance without understanding function, or who cannot articulate the specific mechanism being copied, or who think they need to use real feathers instead of materials with the same smooth property.

Question 20

Design copies an elephant trunk's long reach and grip by using a ruler and binder clip to grab the ball in a tight space. (correct answer)
Design copies an elephant ear's flapping by using paper fans to blow the ball out from behind the washer.
Design copies spider silk by using fishing line to hang the ball from the ceiling so it cannot roll away.
Design copies duck feathers by using wax paper to make the ball waterproof so it rolls out by itself.

Explanation: This question assesses the skill from 1-LS1-1: Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs, focusing on designing solutions that mimic nature. Biomimicry design means copying nature's solutions to solve human problems. The process involves: (1) identifying a human problem, (2) finding an animal or plant with a similar need and observing how its external part solves it, (3) figuring out the mechanism or how it works, (4) designing a human solution that copies that mechanism with available materials, and (5) building and testing it. The key is copying how it works, not just what it looks like; for example, duck feathers are waterproof because their smooth surface makes water roll off, so a raincoat uses smooth plastic to make water roll off using the same mechanism. Carlos's problem was reaching a ball dropped behind the washing machine in a tight space; he looked at an elephant trunk which is long and flexible with a gripping end to reach and grab distant objects. The design uses a ruler, string, a binder clip, and tape to make a long grabber. The design mimics the elephant trunk by extending reach with the ruler and gripping with the clip. This copies the mechanism of length and controllable grip that makes the trunk effective for reaching. The correct answer says 'Design copies an elephant trunk's long reach and grip by using a ruler and binder clip to grab the ball in a tight space' which accurately describes the design's mimicry of nature to solve the reaching problem. The answer shows understanding that the design copies the reach and grip mechanism from the elephant trunk using ruler and clip materials to solve Carlos's problem of inaccessible ball, with the mimicry being functional by copying how it extends and grabs rather than just visual appearance. A distractor like 'Design copies an elephant ear's flapping by using paper fans to blow the ball out from behind the washer' is wrong because it copies the wrong animal part and describes a blowing mechanism instead of reaching. Students might choose this if they confuse which animal part was inspired or do not understand the specific reaching feature, thinking biomimicry means copying any elephant action. Help students design by following steps: (1) Problem: 'I need to reach far,' (2) Nature: 'What animal reaches far? Elephants with trunks,' (3) Mechanism: 'How does it work? Long flexible tube with grip,' (4) Materials: 'What can I use to copy that? Ruler and clip,' (5) Design: Make it! Emphasize copying the mechanism, not just looking like an elephant; 'We are not making trunk costumes, we are copying how trunks reach and grab.' Show before-after: Human problem of unreachable ball → observe trunk's solution → copy reaching mechanism → ball is grabbed! Use a graphic organizer: Problem [box] → Nature Inspiration [box] → How it works [box] → My design [box] → Materials [box]. Let students practice the full cycle with simple examples like this. Watch for students who copy appearance without understanding function, or who cannot articulate the specific mechanism being copied, or who think they need to use real trunks instead of materials with similar extension.
