Question 1

Design a plan to use safe materials and make it fit in a backpack.
Design a new library with more books so students can replace damaged ones.
Design a way to protect library books outdoors while using safe classroom materials that fit in a desk or backpack. (correct answer)
Design a rule that students must keep books inside the library at recess.

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). For example, "design a way to keep plants watered using free materials" identifies both problem (watering plants) and constraint (free materials). In this scenario, students read library books outside at recess, but books get dirty or wet on the grass. The main challenge is protecting library books outdoors, and students must recognize that any solution will be limited by using classroom materials, being safe, and fitting in a desk or backpack. Choice A is correct because it identifies both the design challenge (a way to protect library books outdoors) and acknowledges constraints (safe classroom materials that fit in a desk or backpack). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice D represents focusing on constraints without stating what needs designing. Students who choose this may think listing materials is the same as stating the problem. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 2

Read about the situation. During outdoor reading time, books and papers fall or get wet on the way to the playground. Jamal says, "My pages got soggy again!" Students need a solution using classroom materials that is safe and quick to use in under 5 minutes. Which statement identifies both the problem and what limits the solution?

Design a brand-new backpack with zippers and a rain cover bought at a store.
Design something that is made from recycled materials and takes less than 5 minutes to use.
Design a safe, quick way to carry reading materials outside that keeps them dry, using only classroom or recycled materials. (correct answer)
Design a way to carry books to the playground that keeps them dry and organized.

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). For example, "design a way to keep plants watered using free materials" identifies both problem (watering plants) and constraint (free materials). In this scenario, books and papers fall or get wet during outdoor reading time on the way to the playground, with students needing a solution that uses classroom materials and is safe and quick to use in under 5 minutes. The main challenge is carrying reading materials safely without them getting wet, and students must recognize that any solution will be limited by using only classroom or recycled materials, safety, and time under 5 minutes. Choice A is correct because it identifies both the design challenge (a safe, quick way to carry reading materials outside that keeps them dry) and acknowledges constraints (using only classroom or recycled materials). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice D represents focusing on a solution without constraints, suggesting buying new items. Students who choose this may think any solution is fine without considering limits like cost or available materials. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 3

Look at the problem. In the cafeteria line, trays wobble and milk cartons slide, so food spills. Sofia says, "My milk almost fell off again!" Students need a solution that is safe, uses classroom materials, and is quick to use in under 5 minutes. Which describes what needs to be designed and what constraints must be considered?

Design a plastic tray insert that must be bought online for each student.
Design a new cafeteria with bigger tables and more space for everyone.
Design a rule that students must walk slower in the cafeteria line.
Design a way to carry lunch items safely on a tray using classroom materials, and it must be quick to use. (correct answer)

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). For example, "design a way to keep plants watered using free materials" identifies both problem (watering plants) and constraint (free materials). In this scenario, trays wobble in the cafeteria line, causing milk cartons and food to slide and spill. The main challenge is carrying lunch items safely on a tray, and students must recognize that any solution will be limited by safety, using classroom materials, and being quick to use in under 5 minutes. Choice B is correct because it identifies both the design challenge (a way to carry lunch items safely on a tray) and acknowledges constraints (using classroom materials, and it must be quick to use). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice A represents an overly broad or unrelated solution like redesigning the entire cafeteria. Students who choose this may think big changes are needed instead of targeted designs within constraints. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 4

Look at the problem. In the cafeteria, trays tip and milk spills on the way to tables. Sofia says, "Use safe materials we already have and keep it small." What do students need to design to solve this problem?

Design a rule that students must walk slower in the cafeteria.
Design a bigger cafeteria with more tables and chairs.
Design a better way to carry lunch items safely using classroom materials and fitting on a tray. (correct answer)
Design a game that makes lunch line faster for everyone.

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). In this scenario, trays tip and milk spills as students carry them to tables in the cafeteria. The main challenge is creating a safer way to carry lunch items, and students must recognize that any solution will be limited by using classroom materials and fitting on a tray. Choice B is correct because it identifies both the design challenge (a better way to carry lunch items safely) and acknowledges constraints (using classroom materials and fitting on a tray). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice A represents misidentifying the problem. Students who choose this may confuse a different cafeteria issue (long lines) with the actual problem described (spilling items while carrying trays). To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 5

Read about the situation. The school garden soil gets too dry between waterings, and plants droop. The garden club meets twice a week, but plants need water every day. Chen says, "The soil is dusty when we come back." The solution must be safe and use materials we already have. What do students need to design to solve this problem?

Design a tool that digs deeper holes so plants grow faster.
Design something safe and free, but do not say what it is for.
Design a schedule so students can meet in the garden every day after school.
Design a way to keep soil moist between meetings using safe, reused materials we already have. (correct answer)

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). For example, "design a way to keep plants watered using free materials" identifies both problem (watering plants) and constraint (free materials). In this scenario, the school garden soil dries out between waterings, causing plants to droop, with the garden club meeting only twice a week. The main challenge is keeping the soil moist between meetings, and students must recognize that any solution will be limited by safety and using materials already available. Choice A is correct because it identifies both the design challenge (a way to keep soil moist between meetings) and acknowledges constraints (using safe, reused materials we already have). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice B represents changing the situation instead of designing a solution. Students who choose this may confuse scheduling with engineering a design to address the core issue. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 6

Read about the situation. For outdoor reading time, students carry notebooks and books to the playground, but wind blows papers away. Marcus says, "My worksheets flew off the bench!" The class needs a solution that is safe and can be set up in under 5 minutes using classroom supplies. What is the design problem that needs to be solved?

Design a safe, quick way to keep reading papers together outside using only classroom supplies. (correct answer)
Design a bigger playground so there is less wind near the benches.
Design something that is fast to use and safe, without saying what problem it solves.
Design a rule that students must hold papers with two hands at all times.

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). For example, "design a way to keep plants watered using free materials" identifies both problem (watering plants) and constraint (free materials). In this scenario, during outdoor reading time, wind blows papers away from notebooks and books at the playground. The main challenge is keeping reading papers together outside, and students must recognize that any solution will be limited by safety, setup in under 5 minutes, and using classroom supplies. Choice A is correct because it identifies both the design challenge (a safe, quick way to keep reading papers together outside) and acknowledges constraints (using only classroom supplies). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice C represents focusing on constraints without stating the problem. Students who choose this may think listing limits is the same as defining the design challenge. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 7

Design a new cafeteria with bigger tables and more space for everyone.
Design a way to carry lunch items safely on a tray using classroom materials, and it must be quick to use. (correct answer)
Design a plastic tray insert that must be bought online for each student.
Design a rule that students must walk slower in the cafeteria line.

Practice distinguishing between describing a situation versus identifying a design challenge.

Question 8

Read about the situation. The classroom hamster's water bottle is full in the morning, but it is empty by afternoon. Amir says, "I don't want the hamster to be thirsty." Students need to solve this using safe materials from home or class, with no sharp edges. What challenge needs to be solved, and what makes solving it difficult?

Design something safe and smooth, but do not include any water needs. (correct answer)
Design a water system that uses metal tools and drilling to attach new parts.
Design a way to give the hamster water all day using safe materials we already have, with no sharp edges.
Design a bigger hamster cage so it has more room to run around.

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). For example, "design a way to keep plants watered using free materials" identifies both problem (watering plants) and constraint (free materials). In this scenario, the classroom hamster's water bottle empties by afternoon, risking the hamster getting thirsty. The main challenge is providing water all day, and students must recognize that any solution will be limited by using safe materials from home or class with no sharp edges. Choice A is correct because it identifies both the design challenge (a way to give the hamster water all day) and acknowledges constraints (using safe materials we already have, with no sharp edges). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice C represents using unsafe or inappropriate materials like metal tools. Students who choose this may ignore safety constraints in favor of complex builds. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 9

Look at the problem. In art class, scissors, glue, crayons, and markers are scattered on different tables. Maya says, "I waste time looking for a marker!" The class needs a storage solution using free or recycled materials, and it must fit on a shelf. What is the design problem that needs to be solved?

Design a storage system that sorts art supplies and fits on a shelf, using only free or recycled materials. (correct answer)
Design a shelf that is taller than the students so it holds everything.
Design a plan to buy new markers and scissors for every student.
Design a way for students to draw better pictures during art time.

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). For example, "design a way to keep plants watered using free materials" identifies both problem (watering plants) and constraint (free materials). In this scenario, art supplies like scissors, glue, crayons, and markers are scattered on different tables, causing students to waste time searching. The main challenge is organizing and storing these supplies, and students must recognize that any solution will be limited by using free or recycled materials and fitting on a shelf. Choice B is correct because it identifies both the design challenge (a storage system that sorts art supplies and fits on a shelf) and acknowledges constraints (using only free or recycled materials). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice D represents ignoring constraints by suggesting purchasing new items. Students who choose this may confuse solving the problem with buying solutions instead of designing within limits. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 10

Look at the problem. In the cafeteria, utensils and napkins slide off trays when students carry them to tables. Emma says, "My fork fell on the floor!" Students need a safe solution using classroom materials, and it must work without taking more than 5 minutes. Which statement identifies both the problem and what limits the solution?

Design something that is quick to use and made from classroom materials.
Design a metal tray with built-in clips that needs special tools to build.
Design a way to keep forks from falling off trays.
Design a safe way to keep utensils and napkins from sliding on trays using classroom materials, and it must be quick. (correct answer)

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). For example, "design a way to keep plants watered using free materials" identifies both problem (watering plants) and constraint (free materials). In this scenario, utensils and napkins slide off trays in the cafeteria, causing them to fall. The main challenge is keeping utensils and napkins from sliding on trays, and students must recognize that any solution will be limited by safety, using classroom materials, and working in under 5 minutes. Choice A is correct because it identifies both the design challenge (a safe way to keep utensils and napkins from sliding on trays) and acknowledges constraints (using classroom materials, and it must be quick). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice B represents stating a partial problem without full constraints. Students who choose this may overlook including all limits like materials and time. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 11

Look at the problem. When students carry their lunch trays, forks and napkins slide off the tray. Spills happen near the tables, and Chen says, "I need everything to stay in place." The solution must use recycled or classroom materials, be safe, and be quick to use in under 5 minutes. Which statement identifies both the problem and what limits the solution?

Design a better way to keep all lunch items on the tray using safe recycled materials that is quick to use. (correct answer)
Design a tray with glue on it so everything sticks forever.
Design a plan that uses recycled materials and takes under 5 minutes.
Design a way to make the cafeteria quieter so students can focus.

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). For example, "design a way to keep plants watered using free materials" identifies both problem (watering plants) and constraint (free materials). In this scenario, forks and napkins slide off lunch trays while carrying, leading to spills near tables. The main challenge is keeping all lunch items on the tray, and students must recognize that any solution will be limited by using recycled or classroom materials, being safe, and quick to use in under 5 minutes. Choice A is correct because it identifies both the design challenge (a better way to keep all lunch items on the tray) and acknowledges constraints (safe recycled materials that is quick to use). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice C represents focusing on constraints without stating what needs designing. Students who choose this may think listing materials is the same as stating the problem. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 12

Look at the problem. During outdoor reading, books and pencils fall or get wet. Jamal says, "We must use classroom materials and set up in under 5 minutes." What is the design problem that needs to be solved?

Design a way to carry reading items outside that keeps them dry and uses classroom materials quickly. (correct answer)
Design a plan for reading longer on the playground every day.
Design a backpack with zippers that students buy at a store.
Design a rule that students must hold books with two hands.

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). In this scenario, books and pencils fall or get wet during outdoor reading. The main challenge is creating a way to carry and protect reading items outside, and students must recognize that any solution will be limited by using classroom materials and setting up in under 5 minutes. Choice B is correct because it identifies both the design challenge (a way to carry reading items outside that keeps them dry) and acknowledges constraints (uses classroom materials quickly). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice A represents an impractical solution that ignores constraints. Students who choose this may focus on solving the problem but ignore the requirement to use classroom materials, instead suggesting buying something from a store. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 13

Read about the situation. Markers, glue, and scissors are mixed in one bin. Carlos says, "We need a quick solution in under 5 minutes using classroom materials." What is the design problem that needs to be solved?

Design a way to sort and find art tools fast using classroom materials, ready to use in under 5 minutes. (correct answer)
Design a new art room with more shelves and new bins.
Design a poster telling students to clean up after art.
Design something that takes under 5 minutes to use.

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). In this scenario, art supplies like markers, glue, and scissors are mixed together in one bin, making them hard to find. The main challenge is creating an organization system for quick access, and students must recognize that any solution will be limited by using classroom materials and being ready in under 5 minutes. Choice A is correct because it identifies both the design challenge (a way to sort and find art tools fast) and acknowledges constraints (using classroom materials, ready to use in under 5 minutes). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice D represents stating only constraints without the problem. Students who choose this may focus on the time limit but fail to explain what needs to be designed within that time constraint. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 14

Look at the problem. Students want to read library books during recess outside, but they worry books will get dirty or wet. Keisha says, "I love reading outside, but I don't want to ruin the book." The solution must fit in a backpack and use only free or recycled materials. Which sentence best describes the problem that needs a solution?

Design a waterproof case that must be bought at a store for $20.
Design a free, recycled way to protect library books outdoors that fits in a backpack. (correct answer)
Design a new library with more shelves and a bigger reading area.
Design a plan for students to check out more library books each week.

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). For example, "design a way to keep plants watered using free materials" identifies both problem (watering plants) and constraint (free materials). In this scenario, students want to read library books outside during recess but worry about them getting dirty or wet. The main challenge is protecting the books outdoors, and students must recognize that any solution will be limited by fitting in a backpack and using free or recycled materials. Choice A is correct because it identifies both the design challenge (a free, recycled way to protect library books outdoors) and acknowledges constraints (that fits in a backpack). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice D represents relying on purchased items instead of constraints. Students who choose this may overlook the need for free or recycled materials. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 15

Design a schedule so students can meet in the garden every day after school.
Design something safe and free, but do not say what it is for.
Design a tool that digs deeper holes so plants grow faster.
Design a way to keep soil moist between meetings using safe, reused materials we already have. (correct answer)

A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). For example, "design a way to keep plants watered using free materials" identifies both problem (watering plants) and constraint (free materials). In this scenario, the school garden soil dries out between waterings, causing plants to droop, with the garden club meeting only twice a week. The main challenge is keeping the soil moist between meetings, and students must recognize that any solution will be limited by safety and using materials already available. Choice A is correct because it identifies both the design challenge (a way to keep soil moist between meetings) and acknowledges constraints (using safe, reused materials we already have). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice B represents changing the situation instead of designing a solution. Students who choose this may confuse scheduling with engineering a design to address the core issue. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 16

Look at the problem. Lunch trays slide, and forks and napkins fall on the floor. Emma says, "It must be quick to use and fit on a tray." Which statement identifies both the problem and what limits the solution?

Design a bigger milk carton so it cannot fall over. (correct answer)
Design a better way to carry lunch trays to the table.
Design something that fits on a tray and is quick to use.
Design a way to carry lunch items without sliding that fits on a tray and is quick to use.

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). In this scenario, lunch trays slide and items like forks and napkins fall on the floor. The main challenge is preventing items from sliding off trays, and students must recognize that any solution will be limited by fitting on a tray and being quick to use. Choice A is correct because it identifies both the design challenge (a way to carry lunch items without sliding) and acknowledges constraints (fits on a tray and is quick to use). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice C represents listing constraints without stating the problem. Students who choose this may understand the size and time limitations but miss clearly stating what problem needs to be solved within those constraints. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 17

Look at the problem. The school garden soil dries out between garden club meetings, and plants look wilted. Marcus says, "We need the dirt to stay damp longer." The solution must be free or recycled, safe, and quick to set up in under 5 minutes. Which sentence best describes the problem that needs a solution?

Design a new garden club poster to remind students to water plants.
Design a way to keep garden soil moist between meetings using free or recycled materials that is safe and quick to set up. (correct answer)
Design a list of limits: free materials, safety rules, and under 5 minutes.
Design a way to make plants grow taller than the fence by next week.

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). For example, "design a way to keep plants watered using free materials" identifies both problem (watering plants) and constraint (free materials). In this scenario, school garden soil dries out between meetings, causing plants to wilt and need the dirt to stay damp longer. The main challenge is keeping garden soil moist between meetings, and students must recognize that any solution will be limited by being free or recycled, safe, and quick to set up in under 5 minutes. Choice A is correct because it identifies both the design challenge (a way to keep garden soil moist between meetings) and acknowledges constraints (free or recycled materials that is safe and quick to set up). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice C represents focusing on constraints without stating what needs designing. Students who choose this may think listing materials is the same as stating the problem. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.

Question 18

Look at the problem. In the school garden, the soil feels dry on days the garden club does not meet. Plants droop by the next meeting, and Carlos says, "They need water every day." The solution must use free or recycled materials, be safe, and fit in the garden bed space. What do students need to design to solve this problem?

Design a schedule so the garden club meets every day after school.
Design a bigger garden with more plants so it looks nicer.
Design a way to keep soil moist between meetings using recycled materials that fits safely in the garden bed. (correct answer)
Design a list of limits like free materials and safety rules for gardening.

Explanation: This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). For example, "design a way to keep plants watered using free materials" identifies both problem (watering plants) and constraint (free materials). In this scenario, school garden soil dries out between club meetings, causing plants to droop and need daily watering. The main challenge is keeping soil moist between meetings, and students must recognize that any solution will be limited by using free or recycled materials, being safe, and fitting in the garden bed. Choice A is correct because it identifies both the design challenge (a way to keep soil moist between meetings) and acknowledges constraints (recycled materials that fits safely in the garden bed). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice D represents focusing on constraints without stating what needs designing. Students who choose this may think listing materials is the same as stating the problem. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color.

Question 19

Read about the situation. During art time, crayons and glue sticks roll off the shelves and mix together. Students spend extra time searching, and Yuki says, "I can't find the right color." The solution must be free using recycled materials, fit on one shelf, and be safe (no sharp edges). What is the design problem that needs to be solved?

Design a free, safe organizer that fits on one shelf and keeps art supplies sorted and easy to find. (correct answer)
Design a way for students to draw faster so art time ends sooner.
Design a shelf that is made of metal and bolted to the wall.
Design a list of recycled materials that students can bring from home.

Question 20

Look at the problem. The classroom hamster's water bottle is full in the morning but empty by afternoon. Students worry the hamster gets thirsty, and Amir says, "It needs water all day." The solution must be safe, use materials from home or class, and be quick to refill in under 5 minutes. Which sentence best describes the problem that needs a solution?

Design a hamster cage that is the biggest cage in the whole school.
Design a way to provide hamster water all day using safe home or classroom materials and quick refills. (correct answer)
Design a plan to be safe and finish refilling in under 5 minutes each time.
Design a new class pet that does not need water during the day.
