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. QuestionMultiple choice

Which step should usually come first in an investigation?

Please select an answer first.

Correct answer: A

The correct answer is Ask a focused question about what will be investigated..

  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 clear question gives the investigation a purpose.
  3. Choose the best scientific practice: The correct choice is Ask a focused question about what will be investigated..

A clear question gives the investigation a purpose.

2. QuestionMultiple choice

What should a procedure include?

Please select an answer first.

Correct answer: B

The correct answer is Ordered steps that explain how to carry out the test safely and consistently..

  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 procedure tells another investigator what to do and how to collect data.
  3. Choose the best scientific practice: The correct choice is Ordered steps that explain how to carry out the test safely and consistently..

A procedure tells another investigator what to do and how to collect data.

3. QuestionMultiple choice

Why should procedures be detailed enough for another student to repeat?

Please select an answer first.

Correct answer: C

The correct answer is Repeatability helps check whether the results are consistent..

  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: Clear procedures support reliable repetition and comparison.
  3. Choose the best scientific practice: The correct choice is Repeatability helps check whether the results are consistent..

Clear procedures support reliable repetition and comparison.

4. QuestionMultiple choice

Which action improves the fairness of a ramp and toy-car investigation?

Please select an answer first.

Correct answer: D

The correct answer is Use the same car and ramp, changing only the ramp height being tested..

  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: Controlling the car and surface isolates the effect of ramp height.
  3. Choose the best scientific practice: The correct choice is Use the same car and ramp, changing only the ramp height being tested..

Controlling the car and surface isolates the effect of ramp height.

5. QuestionMultiple choice

What should a conclusion do?

Please select an answer first.

Correct answer: A

The correct answer is Answer the research question using evidence from the data..

  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 conclusion connects the question to observations and measurements.
  3. Choose the best scientific practice: The correct choice is Answer the research question using evidence from the data..

A conclusion connects the question to observations and measurements.

6. QuestionMultiple choice

Which conclusion is evidence-based?

Please select an answer first.

Correct answer: B

The correct answer is The warmer water dissolved sugar faster in three trials, so the results support the prediction under these conditions..

  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 conclusion cites repeated data and limits the claim to the tested conditions.
  3. Choose the best scientific practice: The correct choice is The warmer water dissolved sugar faster in three trials, so the results support the prediction under these conditions..

The conclusion cites repeated data and limits the claim to the tested conditions.

7. QuestionMultiple choice

What should an investigator do if results do not support the hypothesis?

Please select an answer first.

Correct answer: C

The correct answer is Report the results honestly and consider a revised question or additional test..

  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: Unexpected results are useful evidence and may lead to new questions.
  3. Choose the best scientific practice: The correct choice is Report the results honestly and consider a revised question or additional test..

Unexpected results are useful evidence and may lead to new questions.

8. QuestionMultiple choice

Which part of a report explains how the data were collected?

Please select an answer first.

Correct answer: D

The correct answer is The methods or procedure section..

  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: Methods describe the materials, steps, conditions, and measurements.
  3. Choose the best scientific practice: The correct choice is The methods or procedure section..

Methods describe the materials, steps, conditions, and measurements.

9. QuestionMultiple choice

Which communication method can show a pattern in numerical data?

Please select an answer first.

Correct answer: A

The correct answer is A labeled table or graph..

  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: Tables and graphs organize numerical evidence so patterns are easier to see.
  3. Choose the best scientific practice: The correct choice is A labeled table or graph..
