Alabama ACAP Science Practice sets

This Alabama ACAP Science Practice page provides five short practice sets with 10 multiple-choice questions each. The original scenarios help students in the tested Grades 4, 6, and 8 pathways review scientific ideas, evidence, models, data, and problem solving.

Science skills covered

  • Life science, ecosystems, food chains, cells, traits, adaptations, and population resources
  • Water cycle, weather and climate, erosion, seasons, Moon phases, plate movement, and fossils
  • States of matter, mixtures, forces, energy, circuits, density, magnetism, and sound
  • Testable questions, variables, fair tests, repeated trials, models, data tables, and conclusions
  • Engineering criteria and constraints, conservation, environmental impacts, safety, and system design

How to use this page

Complete one 10-question set at a time. Use the evidence in each scenario, diagram description, or data statement before choosing an answer. Review the explanation to connect the observation to the scientific concept.

This is supplemental State Test Practice, State Assessment Practice, and Standardized Test Practice. It does not replace current Alabama State Department of Education guidance, official blueprints, accommodations, or testing schedules.

1. QuestionMultiple choice

Which process allows green plants to use sunlight to make food?

Please select an answer first.

Correct answer: A

The correct answer is Photosynthesis.

  1. Identify the scientific idea: Read the situation, evidence, model, or data and identify the scientific concept the question is testing.
  2. Use the evidence: During photosynthesis, plants use sunlight, water, and carbon dioxide to make food and release oxygen.
  3. Check the explanation: Compare the choice with the evidence. The best answer is Photosynthesis.

During photosynthesis, plants use sunlight, water, and carbon dioxide to make food and release oxygen.

2. QuestionMultiple choice

In the food chain grass → grasshopper → frog → snake, what is the original source of most of the energy?

Please select an answer first.

Correct answer: B

The correct answer is The Sun.

  1. Identify the scientific idea: Read the situation, evidence, model, or data and identify the scientific concept the question is testing.
  2. Use the evidence: Plants capture energy from the Sun. That energy moves through the food chain when organisms eat one another.
  3. Check the explanation: Compare the choice with the evidence. The best answer is The Sun.

Plants capture energy from the Sun. That energy moves through the food chain when organisms eat one another.

3. QuestionMultiple choice

Which trait is most likely inherited rather than learned?

Please select an answer first.

Correct answer: C

The correct answer is Eye color.

  1. Identify the scientific idea: Read the situation, evidence, model, or data and identify the scientific concept the question is testing.
  2. Use the evidence: Eye color is influenced by genes passed from parents. The other choices are learned behaviors or preferences.
  3. Check the explanation: Compare the choice with the evidence. The best answer is Eye color.

Eye color is influenced by genes passed from parents. The other choices are learned behaviors or preferences.

4. QuestionMultiple choice

What role do decomposers such as fungi and many bacteria play in an ecosystem?

Please select an answer first.

Correct answer: D

The correct answer is They break down dead matter and return nutrients to the environment..

  1. Identify the scientific idea: Read the situation, evidence, model, or data and identify the scientific concept the question is testing.
  2. Use the evidence: Decomposers break down dead organisms and waste, helping nutrients return to soil and other parts of the ecosystem.
  3. Check the explanation: Compare the choice with the evidence. The best answer is They break down dead matter and return nutrients to the environment..

Decomposers break down dead organisms and waste, helping nutrients return to soil and other parts of the ecosystem.

5. QuestionMultiple choice

Which cell structure contains genetic material and helps direct many cell activities?

Please select an answer first.

Correct answer: A

The correct answer is The nucleus.

  1. Identify the scientific idea: Read the situation, evidence, model, or data and identify the scientific concept the question is testing.
  2. Use the evidence: The nucleus contains DNA and helps control the activities of a eukaryotic cell.
  3. Check the explanation: Compare the choice with the evidence. The best answer is The nucleus.

The nucleus contains DNA and helps control the activities of a eukaryotic cell.

6. QuestionMultiple choice

A rabbit population increases quickly in a field. Later, the population decreases because there is less food and space. What limited the population?

Please select an answer first.

Correct answer: B

The correct answer is Available resources.

  1. Identify the scientific idea: Read the situation, evidence, model, or data and identify the scientific concept the question is testing.
  2. Use the evidence: Food and space are resources. When they become limited, they can restrict the size of a population.
  3. Check the explanation: Compare the choice with the evidence. The best answer is Available resources.

Food and space are resources. When they become limited, they can restrict the size of a population.

7. QuestionMultiple choice

Why do ducks have webbed feet?

Please select an answer first.

Correct answer: C

The correct answer is Webbed feet help ducks push against water when swimming..

  1. Identify the scientific idea: Read the situation, evidence, model, or data and identify the scientific concept the question is testing.
  2. Use the evidence: The webbing increases the surface area of the feet, helping ducks move through water.
  3. Check the explanation: Compare the choice with the evidence. The best answer is Webbed feet help ducks push against water when swimming..

The webbing increases the surface area of the feet, helping ducks move through water.

8. QuestionMultiple choice

A person walks from a dark room into bright sunlight. The pupils of the eyes become smaller. What does this show?

Please select an answer first.

Correct answer: D

The correct answer is An organism can respond to a change in its environment..

  1. Identify the scientific idea: Read the situation, evidence, model, or data and identify the scientific concept the question is testing.
  2. Use the evidence: Bright light is an environmental stimulus, and the pupils change size as a response.
  3. Check the explanation: Compare the choice with the evidence. The best answer is An organism can respond to a change in its environment..

Bright light is an environmental stimulus, and the pupils change size as a response.

9. QuestionMultiple choice

Bees collect nectar from flowers while carrying pollen between flowers. The flowers are pollinated, and the bees receive food. What type of relationship is this?

Please select an answer first.

Correct answer: A

The correct answer is Mutualism.

  1. Identify the scientific idea: Read the situation, evidence, model, or data and identify the scientific concept the question is testing.
