Please select an answer first.

Correct answer: A

The correct answer is Its motion changes..

  1. Identify the science idea: Determine whether the task asks about a system, pattern, model, cause and effect, evidence, or a design solution.
  2. Use the evidence: An unbalanced force can change an objects speed or direction.
  3. Check the model: Confirm that the selected answer is consistent with the observation, data, diagram, or scientific principle.

An unbalanced force can change an objects speed or direction.

2. QuestionMultiple choice

Which form of energy is stored in a stretched rubber band?

Please select an answer first.

Correct answer: B

The correct answer is Elastic potential energy.

  1. Identify the science idea: Determine whether the task asks about a system, pattern, model, cause and effect, evidence, or a design solution.
  2. Use the evidence: The stretched shape stores energy that can be released when the band moves.
  3. Check the model: Confirm that the selected answer is consistent with the observation, data, diagram, or scientific principle.

The stretched shape stores energy that can be released when the band moves.

3. QuestionMultiple choice

A metal spoon feels colder than a wooden spoon in the same room. What property best explains this?

Please select an answer first.

Correct answer: C

The correct answer is Metal transfers thermal energy more quickly..

  1. Identify the science idea: Determine whether the task asks about a system, pattern, model, cause and effect, evidence, or a design solution.
  2. Use the evidence: Metal is a better conductor, so it transfers thermal energy from the hand more quickly.
  3. Check the model: Confirm that the selected answer is consistent with the observation, data, diagram, or scientific principle.

Metal is a better conductor, so it transfers thermal energy from the hand more quickly.

4. QuestionMultiple choice

What is the main difference between a physical change and a chemical change?

Please select an answer first.

Correct answer: D

The correct answer is A chemical change produces new substances..

  1. Identify the science idea: Determine whether the task asks about a system, pattern, model, cause and effect, evidence, or a design solution.
  2. Use the evidence: Chemical changes rearrange matter into substances with different properties.
  3. Check the model: Confirm that the selected answer is consistent with the observation, data, diagram, or scientific principle.

Chemical changes rearrange matter into substances with different properties.

5. QuestionMultiple choice

Which statement describes conservation of matter in a closed system?

Please select an answer first.

Correct answer: A

The correct answer is The total amount of matter remains constant..

  1. Identify the science idea: Determine whether the task asks about a system, pattern, model, cause and effect, evidence, or a design solution.
  2. Use the evidence: Matter can change form, but the total amount remains constant in a closed system.
  3. Check the model: Confirm that the selected answer is consistent with the observation, data, diagram, or scientific principle.

Matter can change form, but the total amount remains constant in a closed system.

6. QuestionMultiple choice

Why does a circuit with an open switch not light the bulb?

Please select an answer first.

Correct answer: B

The correct answer is The path for electric current is incomplete..

  1. Identify the science idea: Determine whether the task asks about a system, pattern, model, cause and effect, evidence, or a design solution.
  2. Use the evidence: An open switch breaks the conducting path needed for current to flow.
  3. Check the model: Confirm that the selected answer is consistent with the observation, data, diagram, or scientific principle.

An open switch breaks the conducting path needed for current to flow.

7. QuestionMultiple choice

Which wave has the greatest frequency?

Please select an answer first.

Correct answer: C

The correct answer is The wave with the shortest period..

  1. Identify the science idea: Determine whether the task asks about a system, pattern, model, cause and effect, evidence, or a design solution.
  2. Use the evidence: Frequency is the number of cycles per unit time, so a shorter period means greater frequency.
  3. Check the model: Confirm that the selected answer is consistent with the observation, data, diagram, or scientific principle.

Frequency is the number of cycles per unit time, so a shorter period means greater frequency.

8. QuestionMultiple choice

A student pushes two boxes with the same force. Box A has less mass than Box B. Which box will have greater acceleration?

  3. Check the model: Confirm that the selected answer is consistent with the observation, data, diagram, or scientific principle.

For the same force, the object with less mass has greater acceleration.

9. QuestionMultiple choice

What happens to most substances when their temperature increases?

Please select an answer first.

Correct answer: A

The correct answer is Their particles move faster..

  1. Identify the science idea: Determine whether the task asks about a system, pattern, model, cause and effect, evidence, or a design solution.
  2. Use the evidence: Increasing temperature generally increases the average motion of particles.
  3. Check the model: Confirm that the selected answer is consistent with the observation, data, diagram, or scientific principle.
