Question 1

Marcus noticed a problem in the classroom. Finished papers pile up on desks. This makes it hard to keep work clean and safe. Marcus said, "We need an object to hold papers." What is the problem they need to solve?

  1. Students need a place to put finished papers until the teacher collects them. (correct answer)
  2. Students need to work faster so papers do not pile up.
  3. The teacher needs to give less homework to the class.
  4. Students need to make a big paper box with a lid today.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool). Defining a problem means clearly stating what is difficult, not working well, or causing issues. A good problem definition includes: what is happening (the situation), what makes it difficult (the challenge), who is affected, and what is needed (the goal). When we define problems in engineering, we focus on problems that can be solved by creating or improving an object or tool—something physical that can help. The problem definition guides our solution: if the problem is 'books fall out of desks,' we know we need something to hold books in place; if the problem is 'hard to carry multiple items without spilling,' we need something to keep items together and stable. In this scenario, finished papers pile up on desks, making it hard to keep them clean and organized until collection. Choice A is correct because it identifies the need for a storage place, which points to designing a bin or holder. Choice B represents rushing behavior, which happens when students blame speed instead of defining a problem for a tool solution. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (milk spills) and problems (need way to keep milk stable while carrying). Emphasize that good problem definitions are specific enough to guide solutions but don't jump to solutions yet—'need way to hold items' not 'need a tray with holes.' Have students observe situations and practice stating problems clearly. Connect to real engineering: engineers define problems before designing solutions. Watch for students who state solutions (we need a box) instead of problems (we need way to organize), or who are too vague (something is wrong) to guide solution development.

Question 2

Sofia noticed a problem during outdoor learning. The class watches bugs, but they crawl away fast. This makes it hard for students to see them closely. Sofia said, "We need a tool to look safely." Which statement best describes the problem?

  1. Students need a way to see bugs closely without them escaping. (correct answer)
  2. Bugs are too small for students to ever see outside.
  3. Students should run faster so they can catch the bugs.
  4. Students need to make a bug cage with a handle today.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool). Defining a problem means clearly stating what is difficult, not working well, or causing issues.

When we define problems in engineering, we focus on problems that can be solved by creating or improving an object or tool—something physical that can help. The problem definition guides our solution: if the problem is 'books fall out of desks,' we know we need something to hold books in place; if the problem is 'hard to carry multiple items without spilling,' we need something to keep items together and stable. In this scenario, the class is trying to observe bugs outdoors, but the bugs crawl away quickly, making it hard to see them up close. Choice A is correct because it identifies the specific problem of needing a way to view bugs safely without them escaping, which suggests designing a viewer or container. Choice B represents an exaggeration or impossibility, which happens when students make the problem seem unsolvable instead of defining it for a tool-based solution. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (milk spills) and problems (need way to keep milk stable while carrying). Emphasize that good problem definitions are specific enough to guide solutions but don't jump to solutions yet—'need way to hold items' not 'need a tray with holes.'

Question 3

Maya noticed a problem in the school garden. The hose is heavy and hard for kids to carry. Plants still need water each day for the class. Maya said, "We need an object to move water." Which best defines the problem?

  1. Students need a way to bring water to plants without a heavy hose. (correct answer)
  2. Students do not like watering plants after school.
  3. The garden has too many plants for the whole school.
  4. Students need to buy a longer hose for the garden.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool).

The problem definition guides our solution: if the problem is 'books fall out of desks,' we know we need something to hold books in place; if the problem is 'hard to carry multiple items without spilling,' we need something to keep items together and stable. In this scenario, the garden hose is too heavy for kids to carry, but plants need daily watering. Choice A is correct because it defines the problem of needing an easier way to transport water, suggesting a lighter carrier or tool. Choice B represents a preference issue, which happens when students misidentify dislike as the core problem instead of a tool-solvable challenge. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (milk spills) and problems (need way to keep milk stable while carrying).

Question 4

Keisha noticed a problem at the art table. Brushes fall when students bump them. This makes paint spots and slows the class. Keisha said, "We need an object to keep brushes in place." What is the problem Keisha identified?

  1. Students need a way to keep paint brushes from falling and making messes. (correct answer)
  2. Students need to paint only with crayons instead of brushes.
  3. Students are not listening well during art time today.
  4. The art table is too close to the classroom door.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool).

The problem definition guides our solution: if the problem is 'books fall out of desks,' we know we need something to hold books in place; if the problem is 'hard to carry multiple items without spilling,' we need something to keep items together and stable. In this scenario, brushes fall off the art table when bumped, causing paint messes and slowing the class. Choice A is correct because it clearly defines the problem of needing to secure brushes, which suggests designing a holder to prevent falls. Choice B represents suggesting an alternative material, which happens when students jump to a different method instead of defining the problem for a tool solution. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (milk spills) and problems (need way to keep milk stable while carrying). Emphasize that good problem definitions are specific enough to guide solutions but don't jump to solutions yet—'need way to hold items' not 'need a tray with holes.'

Question 5

Yuki noticed a problem after snowy recess. Wet boots drip water onto the classroom floor. This makes puddles and slippery spots for everyone. Yuki said, "We need an object to catch water." Which statement best describes the problem?

  1. Students need a way to keep water from wet boots off the classroom floor. (correct answer)
  2. Students should stop playing in snow so boots stay dry.
  3. The classroom floor is the wrong color for winter days.
  4. Students need to mop the floor every time they enter.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool).

The problem definition guides our solution: if the problem is 'books fall out of desks,' we know we need something to hold books in place; if the problem is 'hard to carry multiple items without spilling,' we need something to keep items together and stable. In this scenario, wet boots drip water on the floor after snowy recess, creating slippery puddles. Choice A is correct because it defines the problem of needing to contain water from boots, suggesting a mat or tray. Choice B represents blaming activity, which happens when students suggest avoiding the situation instead of solving it with a tool. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (milk spills) and problems (need way to keep milk stable while carrying).

Question 6

Jamal noticed a problem in the classroom. Books fall out of desks and are hard to find. This wastes time for students and the teacher. Jamal said, "We need an object to keep books neat." What is the problem they need to solve?

  1. Students need a way to keep desk books organized and easy to reach. (correct answer)
  2. Students should stop bringing so many books to school.
  3. The classroom has too many books for the whole class.
  4. Students need to build a shelf inside every desk today.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool). Defining a problem means clearly stating what is difficult, not working well, or causing issues.

When we define problems in engineering, we focus on problems that can be solved by creating or improving an object or tool—something physical that can help. The problem definition guides our solution: if the problem is 'books fall out of desks,' we know we need something to hold books in place; if the problem is 'hard to carry multiple items without spilling,' we need something to keep items together and stable. In this scenario, books keep falling out of desks, making it hard to find the right book and keeping desks messy, which wastes time. Choice A is correct because it states that students need a way to organize books in desks, which points to creating an organizer or divider. Choice B represents blaming people instead of defining a solvable problem, which happens when students suggest changing behavior rather than using a tool to address the issue. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (milk spills) and problems (need way to keep milk stable while carrying).

Question 7

Emma noticed a problem in the cafeteria. Students carry trays, but food slides and milk tips. This makes spills and messes for the class. Emma said, "We need an object that could keep lunch items steady." Which best defines the problem?

  1. Students need a way to carry lunch items without spilling. (correct answer)
  2. Students are being too careless with their lunch trays.
  3. The cafeteria is too noisy during lunchtime every day.
  4. Students need a new tray with taller sides and cup holes.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool).

The problem definition guides our solution: if the problem is 'books fall out of desks,' we know we need something to hold books in place; if the problem is 'hard to carry multiple items without spilling,' we need something to keep items together and stable. In this scenario, students are trying to carry lunch trays with multiple items, but food slides around and milk tips over, causing spills and messes. Choice A is correct because it identifies the specific problem of needing a way to carry items safely, which clearly suggests designing a holder or carrier. Choice B represents blaming people instead of defining a solvable problem, which happens when students focus on behavior rather than a situation that a tool can fix. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need?

Question 8

Amir noticed a problem on the playground. Kids argue about swings because turns are confusing. This makes recess unfair for many students. Amir said, "We need a tool to keep track." What is the problem to solve?

  1. Students need a way to know whose turn is next on swings. (correct answer)
  2. Students need to stop talking when they line up for swings.
  3. The playground is too big for teachers to watch everyone.
  4. Students need to build more swings for the playground.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool).

In this scenario, kids argue about whose turn it is on the swings because tracking turns is confusing, making recess unfair. Choice A is correct because it identifies the need for a way to track turns, which suggests designing a timer or sign-up tool. Choice B represents an unrelated behavioral issue, which happens when students confuse the core problem with secondary distractions. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (milk spills) and problems (need way to keep milk stable while carrying).

Question 9

Chen noticed a problem at the art table. When students reach, paint brushes roll off. This makes a mess and wastes class time. Chen said, "We need an object to hold brushes." What problem could a new tool solve?

  1. Students need a way to keep paint brushes from falling off tables. (correct answer)
  2. Students keep making too many paintings during art time.
  3. The paint color is too bright for the classroom walls.
  4. Students should be more careful when they reach for brushes.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool).

In this scenario, paint brushes roll off the art table when students reach for them, causing messes and wasting time. Choice A is correct because it clearly defines the problem of needing a way to secure brushes, which points to designing a holder or stand. Choice D represents blaming people instead of defining a tool-solvable problem, which happens when students focus on carelessness rather than a physical solution. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (milk spills) and problems (need way to keep milk stable while carrying).

Question 10

Carlos noticed a problem in the cafeteria. Students carry trays, but forks slide and milk spills. This makes lunch hard for many kids. Carlos said, "We need a tool that helps trays stay steady." What does the tool need to do?

  1. It needs to keep lunch items from sliding and tipping on trays. (correct answer)
  2. It needs to make lunch taste better for every student.
  3. It needs to help students talk more quietly at lunch.
  4. It needs to give students extra time to eat lunch.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool). Defining a problem means clearly stating what is difficult, not working well, or causing issues. A good problem definition includes: what is happening (the situation), what makes it difficult (the challenge), who is affected, and what is needed (the goal). When we define problems in engineering, we focus on problems that can be solved by creating or improving an object or tool—something physical that can help. The problem definition guides our solution: if the problem is 'books fall out of desks,' we know we need something to hold books in place; if the problem is 'hard to carry multiple items without spilling,' we need something to keep items together and stable. In this scenario, students carry lunch trays, but items like forks slide and milk spills, making lunch difficult. Choice A is correct because it specifies what the tool needs to do—prevent sliding and tipping—which defines the problem for an improved tray design. Choice B represents an unrelated goal, which happens when students confuse the problem with subjective improvements like taste instead of physical stability. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (milk spills) and problems (need way to keep milk stable while carrying).

Question 11

Marcus helps water the garden, but the hose is too heavy. What problem needs solving?

  1. Students need a way to move water to plants without a heavy hose. (correct answer)
  2. The garden plants are dry and look droopy.
  3. Students should lift weights to get stronger arms.
  4. The school needs a bigger garden with more flowers.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool). Defining a problem means clearly stating what is difficult, not working well, or causing issues. A good problem definition includes: what is happening (the situation), what makes it difficult (the challenge), who is affected, and what is needed (the goal). When we define problems in engineering, we focus on problems that can be solved by creating or improving an object or tool—something physical that can help. In this scenario, students want to water the school garden, but the hose is too heavy for them to manage easily, making it difficult to care for the plants. Choice A is correct because it clearly defines the problem as needing a way to move water to plants without a heavy hose, which suggests designing a tool like a lightweight watering can, wheeled water carrier, or sprinkler system. Choice B represents stating the result rather than the problem, which happens when students describe what they see (plants are dry and droopy) instead of identifying what makes watering difficult and needs to be solved. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (plants look droopy) and problems (need lighter way to water). Emphasize that good problem definitions are specific enough to guide solutions but don't jump to solutions yet—'need way to move water without heavy hose' not 'need a watering can.' Have students observe situations and practice stating problems clearly.

Question 12

At recess, Maya sees kids argue about swing turns. What is the problem to solve?

  1. The class needs a way to keep track of whose swing turn is next. (correct answer)
  2. Kids argue loudly and the playground feels crowded.
  3. Students should be nicer and stop talking on swings.
  4. The playground needs a new slide and more swings.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool). Defining a problem means clearly stating what is difficult, not working well, or causing issues. A good problem definition includes: what is happening (the situation), what makes it difficult (the challenge), who is affected, and what is needed (the goal). When we define problems in engineering, we focus on problems that can be solved by creating or improving an object or tool—something physical that can help. In this scenario, children at recess argue about whose turn it is to use the swings because there's no clear system for tracking turns. Choice A is correct because it identifies the specific problem of needing a way to keep track of whose swing turn is next, which clearly suggests designing a tool like a turn-taking board, timer, or number system. Choice B represents describing the symptoms and setting rather than defining the problem, which happens when students state what they observe (kids argue, playground feels crowded) instead of identifying what system or tool could solve the issue. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (kids argue) and problems (need way to track turns). Emphasize that good problem definitions are specific enough to guide solutions but don't jump to solutions yet—'need way to track turns' not 'need a sign-up sheet.' Have students observe situations and practice stating problems clearly.

Question 13

Maya saw swing arguments. What problem could a tool help solve?

  1. Kids need a way to remember whose turn is next. (correct answer)
  2. Kids need to swing higher and go faster each turn.
  3. Kids need to stop arguing and just share nicely.
  4. Kids need new swings because the swings are old.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool). Defining a problem means clearly stating what is difficult, not working well, or causing issues. A good problem definition includes: what is happening (the situation), what makes it difficult (the challenge), who is affected, and what is needed (the goal). When we define problems in engineering, we focus on problems that can be solved by creating or improving an object or tool—something physical that can help. In this scenario, Maya saw arguments over swings, where kids forget whose turn is next, leading to disputes during playtime. Choice A is correct because it identifies the specific problem of needing a way to remember whose turn is next, which clearly suggests designing a timer or sign-up tool. Choice C represents a common error of behavioral instruction, which happens when students suggest just sharing nicely instead of defining a problem solvable by a tool. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (arguments happen) and problems (need way to track turns). Emphasize that good problem definitions are specific enough to guide solutions but don't jump to solutions yet—'need way to remember turns' not 'need a timer.' Have students observe situations and practice stating problems clearly. Connect to real engineering: engineers define problems before designing solutions. Watch for students who state solutions (we need a list) instead of problems (we need way to remember), or who are too vague (kids fight) to guide solution development.

Question 14

Emma saw messy desks. What problem could a tool help solve?

  1. Students need a bigger classroom with more shelves.
  2. Books fall out and are hard to find in desks. (correct answer)
  3. Students need to buy new books for every subject.
  4. Students should stop putting papers inside their desks.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool). Defining a problem means clearly stating what is difficult, not working well, or causing issues. A good problem definition includes: what is happening (the situation), what makes it difficult (the challenge), who is affected, and what is needed (the goal). When we define problems in engineering, we focus on problems that can be solved by creating or improving an object or tool—something physical that can help. In this scenario, Emma observed messy desks, where books keep falling out of desks, making it hard to find the right book and keeping desks disorganized. Choice B is correct because it states that books fall out and are hard to find in desks, which points to creating an organizer or divider. Choice A represents a common error of proposing a broad solution, which happens when students suggest changes like a bigger classroom instead of defining the specific organizational issue. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (desks are messy) and problems (need way to organize books). Emphasize that good problem definitions are specific enough to guide solutions but don't jump to solutions yet—'books fall out' not 'need more shelves.' Have students observe situations and practice stating problems clearly. Connect to real engineering: engineers define problems before designing solutions. Watch for students who state solutions (we need bigger desks) instead of problems (we need way to keep books in place), or who are too vague (desks are bad) to guide solution development.

Question 15

Amir saw desks overflow. Which statement best describes the problem?

  1. Students need to read more books at home each night.
  2. Students need a tool to keep desk books neat and easy. (correct answer)
  3. Students need to build a new desk with extra drawers.
  4. Students are messy and should try harder to be neat.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool). Defining a problem means clearly stating what is difficult, not working well, or causing issues. A good problem definition includes: what is happening (the situation), what makes it difficult (the challenge), who is affected, and what is needed (the goal). When we define problems in engineering, we focus on problems that can be solved by creating or improving an object or tool—something physical that can help. In this scenario, Amir saw desks overflow, where books and materials overflow from desks, making them hard to keep neat and accessible. Choice B is correct because it states that students need a tool to keep desk books neat and easy, which points to creating an organizer while defining the need. Choice C represents a common error of jumping to a major solution, which happens when students propose building a new desk instead of defining the organizational problem. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (desks overflow) and problems (need way to keep books neat). Emphasize that good problem definitions are specific enough to guide solutions but don't jump to solutions yet—'need tool for neat books' not 'need extra drawers.' Have students observe situations and practice stating problems clearly. Connect to real engineering: engineers define problems before designing solutions. Watch for students who state solutions (we need new desks) instead of problems (we need way to organize), or who are too vague (desks are full) to guide solution development.

Question 16

In the cafeteria, Jamal carries a tray, but milk tips over. What is the problem?

  1. Students need a way to carry lunch items without spills. (correct answer)
  2. Milk spills make the cafeteria noisy and busy.
  3. Students should hold the tray with two hands.
  4. The cafeteria needs to serve different drinks at lunch.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool). Defining a problem means clearly stating what is difficult, not working well, or causing issues. A good problem definition includes: what is happening (the situation), what makes it difficult (the challenge), who is affected, and what is needed (the goal). When we define problems in engineering, we focus on problems that can be solved by creating or improving an object or tool—something physical that can help. In this scenario, students are carrying lunch trays in the cafeteria, but items like milk cartons tip over easily, causing spills and messes. Choice A is correct because it identifies the specific problem of needing a way to carry lunch items without spills, which clearly suggests designing a tool like a tray with compartments, holders, or barriers to keep items stable. Choice C represents jumping to a behavioral solution instead of defining a problem that needs a tool, which happens when students suggest what people should do differently (hold with two hands) rather than identifying what physical tool could help. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (milk spills) and problems (need way to keep milk stable while carrying). Emphasize that good problem definitions are specific enough to guide solutions but don't jump to solutions yet—'need way to hold items' not 'need a tray with holes.' Have students observe situations and practice stating problems clearly.

Question 17

Outside, Chen tries to watch bugs, but they crawl away fast. What problem is this?

  1. Students need a way to look at bugs closely without them escaping. (correct answer)
  2. Bugs move quickly and students laugh a lot outside.
  3. Students should run faster to catch the bugs.
  4. The class needs to learn every bug name this week.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool). Defining a problem means clearly stating what is difficult, not working well, or causing issues. A good problem definition includes: what is happening (the situation), what makes it difficult (the challenge), who is affected, and what is needed (the goal). When we define problems in engineering, we focus on problems that can be solved by creating or improving an object or tool—something physical that can help. In this scenario, students are trying to observe bugs for science learning, but the bugs crawl away quickly before students can study them closely. Choice A is correct because it identifies the specific problem of needing a way to look at bugs closely without them escaping, which clearly suggests designing a tool like a bug viewer, observation container, or magnifying box with a lid. Choice B represents describing what happens without defining the problem, which happens when students state observations (bugs move quickly, students laugh) instead of identifying what needs to be solved to achieve their goal. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (bugs crawl away) and problems (need way to observe bugs without them escaping). Emphasize that good problem definitions are specific enough to guide solutions but don't jump to solutions yet—'need way to observe' not 'need a jar.' Have students observe situations and practice stating problems clearly.

Question 18

Jamal saw brushes fall. Which best defines the problem in art class?

  1. Students need more paint colors for their pictures.
  2. Paint brushes fall off tables and make a mess. (correct answer)
  3. Students need to build a brush holder with many holes.
  4. The art room is too loud when students are painting.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool). Defining a problem means clearly stating what is difficult, not working well, or causing issues. A good problem definition includes: what is happening (the situation), what makes it difficult (the challenge), who is affected, and what is needed (the goal). When we define problems in engineering, we focus on problems that can be solved by creating or improving an object or tool—something physical that can help. In this scenario, Jamal saw brushes fall, where paint brushes fall off tables during art class, creating messes and interrupting activities. Choice B is correct because it identifies that paint brushes fall off tables and make a mess, which points to creating a holder or stand. Choice C represents a common error of jumping to a solution, which happens when students propose a specific design like building a brush holder instead of defining the underlying stability issue. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (brushes fall) and problems (need way to keep brushes stable). Emphasize that good problem definitions are specific enough to guide solutions but don't jump to solutions yet—'brushes fall off' not 'need a holder with holes.' Have students observe situations and practice stating problems clearly. Connect to real engineering: engineers define problems before designing solutions. Watch for students who state solutions (we need a stand) instead of problems (we need way to prevent falling), or who are too vague (art is messy) to guide solution development.

Question 19

During art, Amir reaches for brushes and they roll off tables. What problem needs solving?

  1. Students need a way to keep paint brushes from falling off tables. (correct answer)
  2. Paint gets on the floor and looks messy.
  3. Students should paint only with crayons today.
  4. The art room needs more colors of paint for projects.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool). Defining a problem means clearly stating what is difficult, not working well, or causing issues. A good problem definition includes: what is happening (the situation), what makes it difficult (the challenge), who is affected, and what is needed (the goal). When we define problems in engineering, we focus on problems that can be solved by creating or improving an object or tool—something physical that can help. In this scenario, during art class, paint brushes roll off tables when students reach for them, causing paint to get on the floor and disrupting the art activity. Choice A is correct because it clearly defines the problem as needing a way to keep paint brushes from falling off tables, which suggests designing a tool like a brush holder, tray with edges, or clip to secure brushes. Choice B represents stating the result or symptom rather than the problem, which happens when students describe what they see (paint on floor, looks messy) instead of identifying what needs to be prevented or solved. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (paint on floor) and problems (need way to keep brushes from rolling). Emphasize that good problem definitions are specific enough to guide solutions but don't jump to solutions yet—'need way to keep brushes in place' not 'need a holder.' Have students observe situations and practice stating problems clearly.

Question 20

Keisha saw papers pile up. What is the problem to solve?

  1. Students need to do less work so desks stay clean.
  2. Finished papers have no place to go on desks. (correct answer)
  3. Students need a new box for finished papers right now.
  4. The teacher should collect papers every two minutes.
Explanation: This question tests 2nd grade ability to define simple problems that could be solved by objects or tools (NGSS K-2-ETS1-1: Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool). Defining a problem means clearly stating what is difficult, not working well, or causing issues. A good problem definition includes: what is happening (the situation), what makes it difficult (the challenge), who is affected, and what is needed (the goal). When we define problems in engineering, we focus on problems that can be solved by creating or improving an object or tool—something physical that can help. In this scenario, Keisha saw papers pile up, where finished papers have no designated place on desks, leading to clutter and disorganization. Choice B is correct because it states that finished papers have no place to go on desks, which points to creating a bin or organizer. Choice C represents a common error of jumping to a solution, which happens when students propose a specific item like a new box instead of defining the storage issue. To help students define problems: Use a problem definition template with questions: (1) What is happening? (2) What makes it difficult? (3) Who is affected? (4) What do we need? Practice with real classroom situations. Model the difference between symptoms (papers pile up) and problems (need place for finished papers). Emphasize that good problem definitions are specific enough to guide solutions but don't jump to solutions yet—'no place for papers' not 'need a box.' Have students observe situations and practice stating problems clearly. Connect to real engineering: engineers define problems before designing solutions. Watch for students who state solutions (we need a tray) instead of problems (we need way to store papers), or who are too vague (desks are cluttered) to guide solution development.
