1. QuestionMultiple choice

An engineer designs a bridge that must hold a specific load and fit across a stream. The load and the space are examples of what?

Please select an answer first.

Correct answer: A

The correct answer is Criteria and constraints.

  1. Identify the scientific idea: Read the situation, evidence, model, or data and identify the scientific concept the question is testing.
  2. Use the evidence: Criteria describe what the design must do, while constraints are limits such as space, materials, time, or cost.
  3. Check the explanation: Compare the choice with the evidence. The best answer is Criteria and constraints.

Criteria describe what the design must do, while constraints are limits such as space, materials, time, or cost.

2. QuestionMultiple choice

Which design would best reduce soil erosion on a steep hill during heavy rain?

Please select an answer first.

Correct answer: B

The correct answer is Planting vegetation with roots that hold soil in place.

  1. Identify the scientific idea: Read the situation, evidence, model, or data and identify the scientific concept the question is testing.
  2. Use the evidence: Plant roots help hold soil together and vegetation slows the movement of rainwater across the surface.
  3. Check the explanation: Compare the choice with the evidence. The best answer is Planting vegetation with roots that hold soil in place.

Plant roots help hold soil together and vegetation slows the movement of rainwater across the surface.

3. QuestionMultiple choice

Why is sunlight considered a renewable energy resource?

Correct answer: C

The correct answer is It is naturally replenished and does not run out from one use..

  1. Identify the scientific idea: Read the situation, evidence, model, or data and identify the scientific concept the question is testing.
  2. Use the evidence: Sunlight is continuously supplied by the Sun, unlike finite fossil fuel deposits.
  3. Check the explanation: Compare the choice with the evidence. The best answer is It is naturally replenished and does not run out from one use..

Sunlight is continuously supplied by the Sun, unlike finite fossil fuel deposits.

4. QuestionMultiple choice

A forest is cleared to build roads and houses. Which environmental effect is most likely?

Please select an answer first.

Correct answer: D

The correct answer is Habitat for many organisms is reduced..

  1. Identify the scientific idea: Read the situation, evidence, model, or data and identify the scientific concept the question is testing.
  2. Use the evidence: Clearing a forest removes shelter and food sources, reducing or changing available habitat.
  3. Check the explanation: Compare the choice with the evidence. The best answer is Habitat for many organisms is reduced..

Clearing a forest removes shelter and food sources, reducing or changing available habitat.

5. QuestionMultiple choice

Which action best conserves freshwater at home?

Please select an answer first.

Correct answer: A

The correct answer is Fixing a leaking faucet and turning off water while brushing teeth.

  1. Identify the scientific idea: Read the situation, evidence, model, or data and identify the scientific concept the question is testing.
  2. Use the evidence: Repairing leaks and reducing unnecessary use conserve freshwater resources.
  3. Check the explanation: Compare the choice with the evidence. The best answer is Fixing a leaking faucet and turning off water while brushing teeth.

Repairing leaks and reducing unnecessary use conserve freshwater resources.

6. QuestionMultiple choice

Which action is safest before a severe thunderstorm arrives?

Please select an answer first.

Correct answer: B

The correct answer is Move indoors and follow trusted weather instructions..

  1. Identify the scientific idea: Read the situation, evidence, model, or data and identify the scientific concept the question is testing.
  2. Use the evidence: Moving indoors and following official instructions reduces exposure to lightning, strong wind, and hail.
  3. Check the explanation: Compare the choice with the evidence. The best answer is Move indoors and follow trusted weather instructions..

Moving indoors and following official instructions reduces exposure to lightning, strong wind, and hail.

7. QuestionMultiple choice
