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 is a glacier?

Please select an answer first.

Correct answer: A

The correct answer is A large, slow-moving mass of ice on land.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: A glacier is a persistent mass of land ice that flows slowly under its own weight.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

A glacier is a persistent mass of land ice that flows slowly under its own weight.

2. QuestionMultiple choice

What does permafrost describe?

Please select an answer first.

Correct answer: B

The correct answer is Ground that remains frozen for at least two consecutive years.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Permafrost is ground that stays at or below freezing for at least two years in a row.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Permafrost is ground that stays at or below freezing for at least two years in a row.

3. QuestionMultiple choice

Which sequence is a reasonable simplified food chain in an Alaska stream ecosystem?

Please select an answer first.

Correct answer: C

The correct answer is Algae → aquatic insects → salmon.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Algae can capture energy, aquatic insects can feed on algae, and salmon can feed on aquatic insects.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Algae can capture energy, aquatic insects can feed on algae, and salmon can feed on aquatic insects.

4. QuestionMultiple choice

Why can Arctic regions experience very long periods of daylight or darkness?

Please select an answer first.

Correct answer: D

The correct answer is Earth axis tilt changes the angle and duration of sunlight during its orbit.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Earth tilt causes the polar regions to face toward or away from the Sun for extended parts of the year.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Earth tilt causes the polar regions to face toward or away from the Sun for extended parts of the year.

5. QuestionMultiple choice

What happens when magma reaches Earth surface during a volcanic eruption?

Please select an answer first.

Correct answer: A

The correct answer is It is called lava.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Magma is molten rock below the surface; once it reaches the surface, it is called lava.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Magma is molten rock below the surface; once it reaches the surface, it is called lava.

6. QuestionMultiple choice

A snow data set lists 12, 15, 18, 18, and 21 inches. What is the mode?

Please select an answer first.

Correct answer: B

The correct answer is 18 inches.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: The mode is the value that occurs most often, and 18 appears twice.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

The mode is the value that occurs most often, and 18 appears twice.

7. QuestionMultiple choice

Why can a layer of fur help an animal survive in cold Alaska conditions?

Please select an answer first.

Correct answer: C

The correct answer is Trapped air in the fur slows the transfer of thermal energy.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Fur can trap insulating air and reduce the rate at which body heat transfers to the surroundings.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Fur can trap insulating air and reduce the rate at which body heat transfers to the surroundings.

8. QuestionMultiple choice

How might an invasive species affect a native Alaska ecosystem?

Please select an answer first.

Correct answer: D

The correct answer is It may compete with native organisms for food, space, or other resources.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: An invasive species can change food webs and resource availability by competing with native organisms.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

An invasive species can change food webs and resource availability by competing with native organisms.

9. QuestionMultiple choice

A glacier monitoring record shows faster melting during years with warmer average temperatures. What conclusion is supported?

Please select an answer first.

Correct answer: A

The correct answer is Warmer conditions may increase the glacier melting rate.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: The observed pattern supports a relationship between warmer conditions and increased melting in this record, without claiming more than the data show.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

The observed pattern supports a relationship between warmer conditions and increased melting in this record, without claiming more than the data show.

10. QuestionMultiple choice

A remote camp wants to compare two water filters. Which procedure is most useful?

Please select an answer first.

Correct answer: B

The correct answer is Pass the same volume of the same source water through each filter and compare turbidity.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Using the same water volume and source controls conditions, while turbidity provides a measurable comparison.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Using the same water volume and source controls conditions, while turbidity provides a measurable comparison.
