1. QuestionMultiple choice

What is the first step in solving an engineering problem?

Please select an answer first.

Correct answer: A

The correct answer is Identify the problem and the goal.

  1. Identify the science idea: Decide whether the question is about living things, matter, Earth systems, design, or evidence.
  2. Use the evidence: Engineers first define what needs to be solved and what the design should do.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

Engineers first define what needs to be solved and what the design should do.

2. QuestionMultiple choice

A team needs to build a bridge over a small gap. Which property is important for the bridge material?

Please select an answer first.

Correct answer: B

The correct answer is Strength.

  1. Identify the science idea: Decide whether the question is about living things, matter, Earth systems, design, or evidence.
  2. Use the evidence: A strong material can support the bridge and the load placed on it.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

A strong material can support the bridge and the load placed on it.

3. QuestionMultiple choice

Why should a team test a design after building it?

Please select an answer first.

Correct answer: C

The correct answer is Testing shows what works and what needs improvement.

  1. Identify the science idea: Decide whether the question is about living things, matter, Earth systems, design, or evidence.
  2. Use the evidence: Test results help engineers improve a design.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

Test results help engineers improve a design.

4. QuestionMultiple choice

Which test is fairest when comparing two paper airplane designs?

Please select an answer first.

Correct answer: D

The correct answer is Use the same launch place and measure both flights.

  1. Identify the science idea: Decide whether the question is about living things, matter, Earth systems, design, or evidence.
  2. Use the evidence: Keeping conditions similar makes the comparison more meaningful.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

Keeping conditions similar makes the comparison more meaningful.

5. QuestionMultiple choice

A cup made of dark paper becomes warmer in sunlight than a cup made of white paper. What could a student investigate next?

Please select an answer first.

Correct answer: A

The correct answer is Whether paper color affects how much the cup warms.

  1. Identify the science idea: Decide whether the question is about living things, matter, Earth systems, design, or evidence.
  2. Use the evidence: The observation suggests a testable question about color and temperature.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

The observation suggests a testable question about color and temperature.

6. QuestionMultiple choice

A team records how much weight each bridge design holds. How can the data help?

Please select an answer first.

Correct answer: B

The correct answer is It can show which design holds the greatest load.

  1. Identify the science idea: Decide whether the question is about living things, matter, Earth systems, design, or evidence.
  2. Use the evidence: Recorded load data allows the team to compare designs.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

Recorded load data allows the team to compare designs.

7. QuestionMultiple choice

Which material would be best for keeping an ice cube from melting quickly?

Please select an answer first.

Correct answer: C

The correct answer is Foam.

  1. Identify the science idea: Decide whether the question is about living things, matter, Earth systems, design, or evidence.
  2. Use the evidence: Foam is a good insulator and slows heat transfer.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

Foam is a good insulator and slows heat transfer.

8. QuestionMultiple choice

Why do scientists and engineers use models?

Please select an answer first.

Correct answer: D

The correct answer is Models help them represent and study things that may be large, small, distant, or complex.

  1. Identify the science idea: Decide whether the question is about living things, matter, Earth systems, design, or evidence.
  2. Use the evidence: A model is a useful representation for studying a system or design.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

A model is a useful representation for studying a system or design.

9. QuestionMultiple choice

What is a design constraint?

Please select an answer first.

Correct answer: A

The correct answer is A limit or requirement the design must meet.

  1. Identify the science idea: Decide whether the question is about living things, matter, Earth systems, design, or evidence.
  2. Use the evidence: Constraints include limits such as size, materials, cost, or safety.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

Constraints include limits such as size, materials, cost, or safety.

10. QuestionMultiple choice

Why is it useful to test a design more than once?

Please select an answer first.

Correct answer: B

The correct answer is Repeated tests help show whether the result is consistent.

  1. Identify the science idea: Decide whether the question is about living things, matter, Earth systems, design, or evidence.
  2. Use the evidence: Repeated trials help identify patterns and reduce the effect of chance.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

Repeated trials help identify patterns and reduce the effect of chance.
