The upward pattern shows a positive relationship between light exposure and measured growth for the tested plants.

3. QuestionMultiple choice

A class tests insulation using cups with equal amounts of water. Which factor should remain constant?

Please select an answer first.

Correct answer: C

The correct answer is The starting temperature and amount of water.

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
  2. Use evidence from the model or investigation: Keeping the starting temperature and water amount constant makes the insulation comparison fair.
  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.

Keeping the starting temperature and water amount constant makes the insulation comparison fair.

4. QuestionMultiple choice

Which statement is the best example of claim-evidence-reasoning?

Please select an answer first.

Correct answer: D

The correct answer is The metal cup kept water warmer because its measured temperature was higher after 20 minutes, showing less heat left the cup..

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
  2. Use evidence from the model or investigation: A scientific explanation connects a claim to measured evidence and explains why the evidence supports it.
  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.

A scientific explanation connects a claim to measured evidence and explains why the evidence supports it.

5. QuestionMultiple choice

Two identical bulbs are connected in series. One bulb is removed. What will most likely happen?

Please select an answer first.

Correct answer: A

The correct answer is The circuit opens and both bulbs go out..

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
  2. Use evidence from the model or investigation: Removing one bulb opens the series path, stopping current through both bulbs.
  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.

Removing one bulb opens the series path, stopping current through both bulbs.

6. QuestionMultiple choice

A food web shows algae eaten by small fish, small fish eaten by larger fish, and larger fish eaten by birds. If algae decrease, what may happen first?

Please select an answer first.

Correct answer: B

The correct answer is Small fish may have less food..

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
