Grade 5 Scientific Investigation Practice Test

Build Grade 5 Science skills with five 10-question practice tests on questions, hypotheses, variables, controls, procedures, data, graphs, conclusions, models, and safety.

Scientific Investigation Practice Tests

These Grade 5 Science practice tests help students plan and evaluate investigations. Students ask testable questions, write hypotheses, identify variables and controls, follow procedures, collect and graph data, draw evidence-based conclusions, use models, and follow safety practices.

Skills covered

  • Writing focused and testable scientific questions
  • Making testable predictions or hypotheses
  • Identifying independent, dependent, and controlled variables
  • Planning fair tests, control groups, and repeated trials
  • Choosing tools, units, tables, and graphs
  • Connecting data to conclusions and recognizing limitations
  • Using models, communicating results, and following safety rules

How to use these practice tests

For each situation, identify what is changed, what is measured, and what is kept the same. Then decide whether the evidence supports the conclusion and whether the procedure is fair, repeatable, safe, and clearly recorded.

  1. Identify the investigation skill: Decide whether the question asks about a question, hypothesis, variable, control, data, conclusion, or safety practice.
  2. Use the evidence: The question includes a factor to change and a measurable result.
  3. Choose the best scientific practice: The correct choice is How does the amount of sunlight affect the height of bean plants?.

The question includes a factor to change and a measurable result.

3. QuestionMultiple choice

What is a hypothesis?

Please select an answer first.

Correct answer: C

The correct answer is A testable prediction about what may happen and why..

  1. Identify the investigation skill: Decide whether the question asks about a question, hypothesis, variable, control, data, conclusion, or safety practice.
  2. Use the evidence: A hypothesis predicts an outcome that evidence can support or fail to support.
  3. Choose the best scientific practice: The correct choice is A testable prediction about what may happen and why..

A hypothesis predicts an outcome that evidence can support or fail to support.

4. QuestionMultiple choice

Which is the best hypothesis for testing sunlight and plant growth?

Please select an answer first.

Correct answer: D

The correct answer is If a plant receives more sunlight within a safe range, then it may grow taller because light supports food production..

  1. Identify the investigation skill: Decide whether the question asks about a question, hypothesis, variable, control, data, conclusion, or safety practice.
  2. Use the evidence: The hypothesis states a relationship between the changed factor, result, and scientific reason.
  3. Choose the best scientific practice: The correct choice is If a plant receives more sunlight within a safe range, then it may grow taller because light supports food production..

The hypothesis states a relationship between the changed factor, result, and scientific reason.

5. QuestionMultiple choice

What should a student do after writing a hypothesis?

Please select an answer first.

Correct answer: A

The correct answer is Plan a fair test that collects evidence related to the prediction..

  1. Identify the investigation skill: Decide whether the question asks about a question, hypothesis, variable, control, data, conclusion, or safety practice.
  2. Use the evidence: The hypothesis must be tested with an organized procedure and evidence.
  3. Choose the best scientific practice: The correct choice is Plan a fair test that collects evidence related to the prediction..

The hypothesis must be tested with an organized procedure and evidence.

6. QuestionMultiple choice

Why should a scientific question be focused?

Please select an answer first.

Correct answer: B

The correct answer is A focused question is easier to test and answer with available time and materials..

  1. Identify the investigation skill: Decide whether the question asks about a question, hypothesis, variable, control, data, conclusion, or safety practice.
  2. Use the evidence: A manageable question leads to a clear procedure and relevant data.
  3. Choose the best scientific practice: The correct choice is A focused question is easier to test and answer with available time and materials..

A manageable question leads to a clear procedure and relevant data.

7. QuestionMultiple choice

Which observation can be used as evidence in a plant investigation?

Please select an answer first.

Correct answer: C

The correct answer is The plant grew 4 centimeters in two weeks..

  1. Identify the investigation skill: Decide whether the question asks about a question, hypothesis, variable, control, data, conclusion, or safety practice.
  2. Use the evidence: A measured change in height is evidence that can be recorded and compared.
  3. Choose the best scientific practice: The correct choice is The plant grew 4 centimeters in two weeks..

A measured change in height is evidence that can be recorded and compared.

8. QuestionMultiple choice

Which statement about a hypothesis is accurate?

Please select an answer first.

Correct answer: D

The correct answer is Evidence may support or fail to support a hypothesis; either result can teach the investigator something..

  1. Identify the investigation skill: Decide whether the question asks about a question, hypothesis, variable, control, data, conclusion, or safety practice.
  2. Use the evidence: Scientific investigations use evidence to evaluate predictions rather than guarantee them.
  3. Choose the best scientific practice: The correct choice is Evidence may support or fail to support a hypothesis; either result can teach the investigator something..

Scientific investigations use evidence to evaluate predictions rather than guarantee them.
