Alaska Science Assessment practice sets

This Alaska Science Assessment Practice Test page provides five short practice sets with 10 original multiple-choice questions each. The sets are designed for Grades 5, 8, and 10 review across physical science, life science, Earth and space science, engineering design, data interpretation, and Alaska-related phenomena.

Skills covered

  • Properties of matter, physical and chemical changes, forces, energy, waves, circuits, and density
  • Cells, photosynthesis, food webs, adaptations, populations, decomposers, genetics, and natural selection
  • Water cycle, seasons, rocks, plate tectonics, weather, climate, Moon phases, earthquakes, and greenhouse gases
  • Testable questions, variables, repeated trials, models, constraints, data displays, criteria, and evidence-based claims
  • Glaciers, permafrost, salmon ecosystems, Arctic daylight, volcanoes, snow data, invasive species, and field investigations

How to use this page

Complete one 10-question set at a time. Identify the evidence, connect it to the science idea, and check whether the conclusion is supported by the data. Review each explanation after responding.

This is supplemental State Test Practice, State Assessment Practice, and Standardized Test Practice. It does not replace current Alaska Department of Education and Early Development guidance, official assessment materials, accommodations, or testing schedules.

1. QuestionMultiple choice

What happens when water vapor cools and changes into tiny liquid droplets?

Please select an answer first.

Correct answer: A

The correct answer is Condensation occurs.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Condensation changes water vapor into liquid droplets, which can form clouds.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Condensation changes water vapor into liquid droplets, which can form clouds.

2. QuestionMultiple choice

What is the main cause of seasons on Earth?

Please select an answer first.

Correct answer: B

The correct answer is The tilt of Earth as it orbits the Sun.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Earth axis tilt changes the angle and duration of sunlight received by each hemisphere during its orbit.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Earth axis tilt changes the angle and duration of sunlight received by each hemisphere during its orbit.

3. QuestionMultiple choice

How does sedimentary rock commonly form?

Please select an answer first.

Correct answer: C

The correct answer is Sediments are compacted and cemented together.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Layers of sediment can be pressed together and cemented over time to form sedimentary rock.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Layers of sediment can be pressed together and cemented over time to form sedimentary rock.

4. QuestionMultiple choice

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

Please select an answer first.

Correct answer: D

The correct answer is A divergent boundary.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: At a divergent boundary, plates separate and new crust can form between them.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

At a divergent boundary, plates separate and new crust can form between them.

5. QuestionMultiple choice

Which statement correctly compares weather and climate?

Please select an answer first.

Correct answer: A

The correct answer is Weather is short-term atmospheric conditions, while climate is a long-term pattern.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Weather describes conditions over short periods, while climate summarizes patterns over much longer periods.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Weather describes conditions over short periods, while climate summarizes patterns over much longer periods.

6. QuestionMultiple choice

Why does the Moon appear to have different phases?

Please select an answer first.

Correct answer: B

The correct answer is We see different portions of its sunlit half as it orbits Earth.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: The Moon reflects sunlight, and its position relative to Earth and the Sun changes the visible lit portion.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

The Moon reflects sunlight, and its position relative to Earth and the Sun changes the visible lit portion.

7. QuestionMultiple choice

What is one cause of earthquakes in Alaska?

Please select an answer first.

Correct answer: C

The correct answer is Movement of tectonic plates along faults.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Plate movement can build stress along faults, and a sudden release of that stress causes an earthquake.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Plate movement can build stress along faults, and a sudden release of that stress causes an earthquake.

8. QuestionMultiple choice

How do greenhouse gases affect Earth system temperature?

Please select an answer first.

Correct answer: D

The correct answer is They absorb and re-radiate some outgoing heat.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Greenhouse gases interact with outgoing infrared energy and can increase heat retained in the atmosphere.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Greenhouse gases interact with outgoing infrared energy and can increase heat retained in the atmosphere.

9. QuestionMultiple choice

What process adds water vapor to the air when plants release water through their leaves?

Please select an answer first.

Correct answer: A

The correct answer is Transpiration.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Transpiration is the release of water vapor from plant leaves into the atmosphere.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Transpiration is the release of water vapor from plant leaves into the atmosphere.

10. QuestionMultiple choice

Why does the Sun appear to move across the sky each day?

Please select an answer first.

Correct answer: B

The correct answer is Earth rotates on its axis.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Earth rotation makes the Sun appear to travel across the sky from east to west.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Earth rotation makes the Sun appear to travel across the sky from east to west.
