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

Which question can be tested to compare insulation materials?

Please select an answer first.

Correct answer: A

The correct answer is Which material keeps the same volume of water warmest for two hours?.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: A testable question identifies measurable variables and can be investigated with a controlled procedure.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

A testable question identifies measurable variables and can be investigated with a controlled procedure.

2. QuestionMultiple choice

A student tests three insulation materials. What is the independent variable?

Please select an answer first.

Correct answer: B

The correct answer is The type of insulation material.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: The independent variable is the factor intentionally changed by the investigator.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

The independent variable is the factor intentionally changed by the investigator.

3. QuestionMultiple choice

Why should an investigation include repeated trials?

Please select an answer first.

Correct answer: C

The correct answer is Repeated trials improve reliability by showing whether a result is consistent.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Repeating trials helps identify patterns and reduces the effect of an unusual result.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Repeating trials helps identify patterns and reduces the effect of an unusual result.

4. QuestionMultiple choice

What is a limitation of a model of a volcano made from clay?

Please select an answer first.

Correct answer: D

The correct answer is It may not show the full scale, pressure, or chemical composition of a real volcano.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Models represent selected features and may leave out scale, materials, or processes that matter in the real system.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Models represent selected features and may leave out scale, materials, or processes that matter in the real system.

5. QuestionMultiple choice

Which example is an engineering constraint?

Please select an answer first.

Correct answer: A

The correct answer is The design must use only the available materials and stay within the time limit.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Constraints are limits such as materials, cost, time, size, or safety requirements.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Constraints are limits such as materials, cost, time, size, or safety requirements.

6. QuestionMultiple choice

A table lists the temperature of four materials after heating. Which display best compares the final temperatures?

Please select an answer first.

Correct answer: B

The correct answer is A bar graph with one bar for each material.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: A bar graph makes it easy to compare measured values for separate categories.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

A bar graph makes it easy to compare measured values for separate categories.

7. QuestionMultiple choice

How can a student make a test of paper airplane designs fair?

Please select an answer first.

Correct answer: C

The correct answer is Change only the airplane design while keeping paper, launch method, and measuring method the same.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: A fair test changes one main variable and controls other conditions that could affect the result.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

A fair test changes one main variable and controls other conditions that could affect the result.

8. QuestionMultiple choice

A warming shelter design must be safe and reduce heat loss. These statements are examples of what?

Please select an answer first.

Correct answer: D

The correct answer is Criteria for evaluating the solution.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Criteria describe the features a successful engineering solution must meet.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Criteria describe the features a successful engineering solution must meet.

9. QuestionMultiple choice

A prototype does not hold the required weight. What should engineers do next?

Please select an answer first.

Correct answer: A

The correct answer is Use the test evidence to revise the design and test it again.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Engineering is iterative, so test results guide redesign and further testing.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Engineering is iterative, so test results guide redesign and further testing.

10. QuestionMultiple choice

Which claim is best supported by repeated measurements showing that filter A produces clearer water than filters B and C?

Please select an answer first.

Correct answer: B

The correct answer is Under the tested conditions, filter A removed more visible particles.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: A claim should match the evidence and remain limited to the conditions that were actually tested.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

A claim should match the evidence and remain limited to the conditions that were actually tested.
