1. QuestionMultiple choice

What happens to the particles of a substance when it is heated?

Please select an answer first.

Correct answer: A

The correct answer is They generally move faster..

  1. Read the ISA science task: Identify the system, evidence, variables, or model described in the question.
  2. Use the evidence: Heating usually increases particle motion and can change the state of matter.
  3. Check the claim: Confirm that the answer is supported by the information in the question and matches the scientific concept.

Heating usually increases particle motion and can change the state of matter.

2. QuestionMultiple choice

Which example shows a chemical change?

Please select an answer first.

Correct answer: B

The correct answer is Iron forms rust..

  1. Read the ISA science task: Identify the system, evidence, variables, or model described in the question.
  2. Use the evidence: Rust forms a new substance when iron reacts with oxygen and water.
  3. Check the claim: Confirm that the answer is supported by the information in the question and matches the scientific concept.

Rust forms a new substance when iron reacts with oxygen and water.

3. QuestionMultiple choice

A ball rolls down a ramp. Which force pulls the ball toward the ground?

Please select an answer first.

Correct answer: C

The correct answer is Gravity.

  1. Read the ISA science task: Identify the system, evidence, variables, or model described in the question.
  2. Use the evidence: Gravity pulls objects toward Earth and contributes to the ball moving down the ramp.
  3. Check the claim: Confirm that the answer is supported by the information in the question and matches the scientific concept.

Gravity pulls objects toward Earth and contributes to the ball moving down the ramp.

4. QuestionMultiple choice

Which material is the best conductor of electrical energy?

Please select an answer first.

Correct answer: D

The correct answer is Copper.

  1. Read the ISA science task: Identify the system, evidence, variables, or model described in the question.
  2. Use the evidence: Copper allows electric charge to move easily and is commonly used in wires.
  3. Check the claim: Confirm that the answer is supported by the information in the question and matches the scientific concept.

Copper allows electric charge to move easily and is commonly used in wires.

5. QuestionMultiple choice

What type of energy is stored in a stretched rubber band?

Please select an answer first.

Correct answer: A

The correct answer is Elastic potential energy.

  1. Read the ISA science task: Identify the system, evidence, variables, or model described in the question.
  2. Use the evidence: A stretched rubber band stores energy because of its position and deformation.
  3. Check the claim: Confirm that the answer is supported by the information in the question and matches the scientific concept.

A stretched rubber band stores energy because of its position and deformation.

6. QuestionMultiple choice

A student pushes a box, but it does not move. Which statement is best?

Please select an answer first.

Correct answer: B

The correct answer is The forces may be balanced..

  1. Read the ISA science task: Identify the system, evidence, variables, or model described in the question.
  2. Use the evidence: If the box does not accelerate, the push may be balanced by friction or another force.
  3. Check the claim: Confirm that the answer is supported by the information in the question and matches the scientific concept.

If the box does not accelerate, the push may be balanced by friction or another force.

7. QuestionMultiple choice

Which property can be measured without changing what a substance is?

Please select an answer first.

Correct answer: C

The correct answer is Mass.

  1. Read the ISA science task: Identify the system, evidence, variables, or model described in the question.
  2. Use the evidence: Mass is a physical property that can be measured without creating a new substance.
  3. Check the claim: Confirm that the answer is supported by the information in the question and matches the scientific concept.

Mass is a physical property that can be measured without creating a new substance.

8. QuestionMultiple choice

Why does a metal spoon feel colder than a wooden spoon in the same room?

Please select an answer first.

Correct answer: D

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

  1. Read the ISA science task: Identify the system, evidence, variables, or model described in the question.
  2. Use the evidence: Metal is a better thermal conductor, so it draws heat from your hand faster.
  3. Check the claim: Confirm that the answer is supported by the information in the question and matches the scientific concept.

Metal is a better thermal conductor, so it draws heat from your hand faster.

9. QuestionMultiple choice

A ramp is made steeper while the same object is released from the same height. What should the student do to make a fair test?

Please select an answer first.

Correct answer: A

The correct answer is Keep the object and measurement method the same..

  1. Read the ISA science task: Identify the system, evidence, variables, or model described in the question.
  2. Use the evidence: Keeping other conditions constant makes the ramp angle the main variable being tested.
  3. Check the claim: Confirm that the answer is supported by the information in the question and matches the scientific concept.

Keeping other conditions constant makes the ramp angle the main variable being tested.

10. QuestionMultiple choice

What happens when two magnets have the same pole facing each other?

Please select an answer first.

Correct answer: B

The correct answer is They repel..

  1. Read the ISA science task: Identify the system, evidence, variables, or model described in the question.
