Gravity attracts objects toward Earth.

5. QuestionMultiple choice

A toy car travels farther when pushed harder on the same floor. What variable was changed?

Please select an answer first.

Correct answer: A

The correct answer is The force of the push.

  1. Read the Idaho science task: Identify the system, evidence, variable, model, or scientific pattern the question asks you to examine.
  2. Use scientific evidence: The strength of the push is the factor changed in the comparison.
  3. Check the conclusion: Confirm that the answer matches the evidence, uses the correct relationship, and does not claim more than the data show.

The strength of the push is the factor changed in the comparison.

6. QuestionMultiple choice

Why does a ramp make it easier to move a heavy box to a higher place?

Please select an answer first.

Correct answer: B

The correct answer is It spreads the work over a longer distance..

  1. Read the Idaho science task: Identify the system, evidence, variable, model, or scientific pattern the question asks you to examine.
  2. Use scientific evidence: A ramp reduces the force needed at one time by increasing the distance over which the box moves.
  3. Check the conclusion: Confirm that the answer matches the evidence, uses the correct relationship, and does not claim more than the data show.

A ramp reduces the force needed at one time by increasing the distance over which the box moves.

7. QuestionMultiple choice

A circuit contains a battery, wires, and a bulb. What must be true for the bulb to light?

Please select an answer first.

Correct answer: C

The correct answer is The circuit must be closed..

  1. Read the Idaho science task: Identify the system, evidence, variable, model, or scientific pattern the question asks you to examine.
  2. Use scientific evidence: A closed conducting path allows electric current to reach the bulb.
  3. Check the conclusion: Confirm that the answer matches the evidence, uses the correct relationship, and does not claim more than the data show.

A closed conducting path allows electric current to reach the bulb.

8. QuestionMultiple choice
