1. QuestionMultiple choice

Ice melts into liquid water. What type of change is this?

Please select an answer first.

Correct answer: A

The correct answer is A physical change.

  1. Read the task: Identify the claim, quantity, relationship, or scientific idea the question is testing.
  2. Use the evidence: The substance remains water; only its state changes, so the change is physical.
  3. Check the answer: Choose the option that is best supported by the passage, calculation, data, or model.

The substance remains water; only its state changes, so the change is physical.

2. QuestionMultiple choice

What is the main source of energy for most ecosystems?

Please select an answer first.

Correct answer: B

The correct answer is The Moon.

  1. Read the task: Identify the claim, quantity, relationship, or scientific idea the question is testing.
  2. Use the evidence: Producers capture light energy from the Sun and use it to make food.
  3. Check the answer: Choose the option that is best supported by the passage, calculation, data, or model.

Producers capture light energy from the Sun and use it to make food.

3. QuestionMultiple choice

What net force acts on a 2-kilogram object accelerating at 4 meters per second squared?

Please select an answer first.

Correct answer: C

The correct answer is 2 newtons.

  1. Read the task: Identify the claim, quantity, relationship, or scientific idea the question is testing.
  2. Use the evidence: Newton’s second law gives force equals mass times acceleration: 2 × 4 = 8 newtons.
  3. Check the answer: Choose the option that is best supported by the passage, calculation, data, or model.

Newton’s second law gives force equals mass times acceleration: 2 × 4 = 8 newtons.

4. QuestionMultiple choice

A wave has a frequency of 2 hertz. What is its period?

Please select an answer first.

Correct answer: D

The correct answer is 2 seconds.

  1. Read the task: Identify the claim, quantity, relationship, or scientific idea the question is testing.
  2. Use the evidence: Period is the reciprocal of frequency: 1 divided by 2 equals 0.5 seconds.
  3. Check the answer: Choose the option that is best supported by the passage, calculation, data, or model.

Period is the reciprocal of frequency: 1 divided by 2 equals 0.5 seconds.

5. QuestionMultiple choice

If the number of hawks in an ecosystem increases greatly, what may happen to the mouse population?

Please select an answer first.

Correct answer: A

The correct answer is It may decrease because more mice are eaten..

  1. Read the task: Identify the claim, quantity, relationship, or scientific idea the question is testing.
  2. Use the evidence: More predators can increase predation and reduce the number of prey.
  3. Check the answer: Choose the option that is best supported by the passage, calculation, data, or model.

More predators can increase predation and reduce the number of prey.

6. QuestionMultiple choice

What type of plate boundary forms where two tectonic plates move apart?

Please select an answer first.

Correct answer: B

The correct answer is Convergent.

  1. Read the task: Identify the claim, quantity, relationship, or scientific idea the question is testing.
  2. Use the evidence: A divergent boundary occurs where plates move away from each other.
  3. Check the answer: Choose the option that is best supported by the passage, calculation, data, or model.

A divergent boundary occurs where plates move away from each other.

7. QuestionMultiple choice

What process changes water vapor into liquid water?

Please select an answer first.

Correct answer: C

The correct answer is Evaporation.

  1. Read the task: Identify the claim, quantity, relationship, or scientific idea the question is testing.
  2. Use the evidence: Condensation occurs when water vapor cools and becomes liquid.
  3. Check the answer: Choose the option that is best supported by the passage, calculation, data, or model.

Condensation occurs when water vapor cools and becomes liquid.

8. QuestionMultiple choice

A population of bacteria becomes less affected by an antibiotic over many generations. Which explanation is most consistent with natural selection?

Please select an answer first.

Correct answer: D

The correct answer is Every bacterium chooses to change when it sees the medicine..

  1. Read the task: Identify the claim, quantity, relationship, or scientific idea the question is testing.
  2. Use the evidence: Bacteria with heritable resistance are more likely to survive and reproduce in the presence of the antibiotic.
  3. Check the answer: Choose the option that is best supported by the passage, calculation, data, or model.

Bacteria with heritable resistance are more likely to survive and reproduce in the presence of the antibiotic.

9. QuestionMultiple choice
