1. QuestionMultiple choice

What should an engineer identify before designing a solution to a problem?

Please select an answer first.

Correct answer: A

The correct answer is The problem, criteria, and constraints.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Criteria define success and constraints define limits on the design.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Criteria define success and constraints define limits on the design.

2. QuestionMultiple choice

In an experiment testing how light affects plant growth, what is the independent variable?

Please select an answer first.

Correct answer: B

The correct answer is The amount of light.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: The independent variable is the factor deliberately changed by the investigator.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

The independent variable is the factor deliberately changed by the investigator.

3. QuestionMultiple choice

Why should scientists repeat trials in an investigation?

Please select an answer first.

Correct answer: C

The correct answer is Repeated trials increase confidence in a pattern.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Repeated trials help distinguish a consistent pattern from a random result.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Repeated trials help distinguish a consistent pattern from a random result.

4. QuestionMultiple choice

A graph shows that plant growth rises as fertilizer amount increases, then levels off. What does the graph suggest?

Please select an answer first.

Correct answer: D

The correct answer is More fertilizer helps only up to a point.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: The leveling off indicates that another factor may limit growth after a certain amount.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

The leveling off indicates that another factor may limit growth after a certain amount.

5. QuestionMultiple choice

In a test of different paper towel brands, why should the amount of water be kept the same?

Please select an answer first.

Correct answer: A

The correct answer is It is a controlled variable that makes the comparison fair.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Keeping water amount constant ensures the brand is the main factor being compared.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Keeping water amount constant ensures the brand is the main factor being compared.

6. QuestionMultiple choice

What is a limitation of a model of a volcano made from clay?

Please select an answer first.

Correct answer: B

The correct answer is It may not represent the exact materials and forces inside a real volcano.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Models simplify systems, so they cannot capture every real-world property.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Models simplify systems, so they cannot capture every real-world property.

7. QuestionMultiple choice

Which feature is a useful design criterion for a water filter?

Please select an answer first.

Correct answer: C

The correct answer is The filter removes a specified amount of particles.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: A measurable removal requirement tells engineers whether the design works.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

A measurable removal requirement tells engineers whether the design works.

8. QuestionMultiple choice

A prototype fails a safety test. What is the best next step?

Please select an answer first.

Correct answer: D

The correct answer is Use the test data to revise the design and test it again.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Engineering uses evidence from testing to improve a design iteratively.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Engineering uses evidence from testing to improve a design iteratively.

9. QuestionMultiple choice

A school wants to reduce stormwater runoff. Which design is most directly related to the goal?

Please select an answer first.

Correct answer: A

The correct answer is A rain garden that allows water to soak into the soil.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: A rain garden captures runoff and increases infiltration into the ground.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

A rain garden captures runoff and increases infiltration into the ground.

10. QuestionMultiple choice

Which statement is a scientific claim that can be tested?

Please select an answer first.

Correct answer: B

The correct answer is Salt dissolves faster in warm water than in cold water.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: The claim makes a measurable comparison that can be tested experimentally.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

The claim makes a measurable comparison that can be tested experimentally.
