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 observation describes a physical property of a solid?

Please select an answer first.

Correct answer: A

The correct answer is It has a definite shape and volume.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: A definite shape and volume can be observed without changing the substance into a new substance.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

A definite shape and volume can be observed without changing the substance into a new substance.

2. QuestionMultiple choice

An ice cube melts in a warm room. What kind of change occurs?

Please select an answer first.

Correct answer: B

The correct answer is A physical change.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Melting changes the state of water from solid to liquid, but the substance remains water.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Melting changes the state of water from solid to liquid, but the substance remains water.

3. QuestionMultiple choice

Which force opposes motion between two surfaces that touch?

Please select an answer first.

Correct answer: C

The correct answer is Friction.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Friction acts between touching surfaces and resists their relative motion.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Friction acts between touching surfaces and resists their relative motion.

4. QuestionMultiple choice

When light enters water from air and changes direction, what is this effect called?

Please select an answer first.

Correct answer: D

The correct answer is Refraction.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Refraction is the bending of light as it moves between materials where its speed changes.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Refraction is the bending of light as it moves between materials where its speed changes.

5. QuestionMultiple choice

In which situation will a bulb in a simple circuit light?

Please select an answer first.

Correct answer: A

The correct answer is The switch is closed and the circuit is complete.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: A complete conducting path allows electric current to move through the bulb.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

A complete conducting path allows electric current to move through the bulb.

6. QuestionMultiple choice

A metal spoon is placed in hot soup. Which energy transfer occurs?

Please select an answer first.

Correct answer: B

The correct answer is Thermal energy moves from the hot soup to the cooler spoon.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Thermal energy transfers from a warmer object to a cooler object until temperatures become closer.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Thermal energy transfers from a warmer object to a cooler object until temperatures become closer.

7. QuestionMultiple choice

Which example is a chemical change?

Please select an answer first.

Correct answer: C

The correct answer is Iron rusting.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Rusting forms a new substance through a chemical reaction between iron, oxygen, and water.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Rusting forms a new substance through a chemical reaction between iron, oxygen, and water.

8. QuestionMultiple choice

A sound wave has a higher frequency than another sound wave. What property is higher?

Please select an answer first.

Correct answer: D

The correct answer is Pitch.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Frequency describes how often a wave repeats, and higher sound frequency is heard as higher pitch.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Frequency describes how often a wave repeats, and higher sound frequency is heard as higher pitch.

9. QuestionMultiple choice

What happens to an object when balanced forces act on it?

Please select an answer first.

Correct answer: A

The correct answer is It remains at rest or continues at constant speed in a straight line.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: Balanced forces produce no change in motion, so the object stays at rest or keeps its constant motion.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

Balanced forces produce no change in motion, so the object stays at rest or keeps its constant motion.

10. QuestionMultiple choice

Two objects have the same volume. Which object is more dense?

Please select an answer first.

Correct answer: B

The correct answer is The object with greater mass.

  1. Identify the evidence: Read the observation, model, data, or system described in the question.
  2. Apply the science idea: For equal volumes, the object with greater mass has more matter packed into the same space and is more dense.
  3. Check the conclusion: Confirm that the answer is supported by the evidence and fits the scientific relationship.

For equal volumes, the object with greater mass has more matter packed into the same space and is more dense.
