Grade 6 Scientific Method and Data Practice Test

Build Grade 6 Science skills with five 10-question practice tests on scientific questions, hypotheses, variables, controls, data tables, graphs, evidence, conclusions, reliability, and safety.

Scientific Method and Data Practice Tests

These Grade 6 Science practice tests help students plan fair investigations, collect useful evidence, organize data, and explain results. Students practice questions, hypotheses, independent and dependent variables, controls, procedures, qualitative and quantitative data, tables, graphs, averages, claims, reasoning, reliability, accuracy, limitations, and laboratory safety.

Skills covered

  • Writing testable questions and hypotheses
  • Identifying independent, dependent, and controlled variables
  • Designing fair procedures and comparison conditions
  • Distinguishing qualitative and quantitative data
  • Choosing tables and graphs for different data sets
  • Interpreting evidence, averages, patterns, reliability, accuracy, conclusions, and limitations

How to use these practice tests

Start by identifying the question and the variable being changed. Then find what is measured and which conditions must stay the same. When analyzing results, use the data rather than the prediction, look for patterns across trials, and write a conclusion that matches the evidence without making a claim broader than the investigation.

1. QuestionMultiple choice

What is the independent variable?

Please select an answer first.

Correct answer: A

The correct answer is The factor a scientist changes on purpose.

  1. Identify the investigation skill: Determine whether the question asks about a question, hypothesis, variable, data display, conclusion, or safety practice.
  2. Use the evidence: The independent variable is deliberately changed to test its effect.
  3. Check the design: Confirm that the procedure is fair, measurements are recorded clearly, and the conclusion matches the evidence.

The independent variable is deliberately changed to test its effect.

2. QuestionMultiple choice

What is the dependent variable?

Please select an answer first.

Correct answer: B

The correct answer is The factor that is measured or observed as a result.

  1. Identify the investigation skill: Determine whether the question asks about a question, hypothesis, variable, data display, conclusion, or safety practice.
  2. Use the evidence: The dependent variable responds to changes in the independent variable and is measured.
  3. Check the design: Confirm that the procedure is fair, measurements are recorded clearly, and the conclusion matches the evidence.

The dependent variable responds to changes in the independent variable and is measured.

3. QuestionMultiple choice

What is a controlled variable?

Please select an answer first.

Correct answer: C

The correct answer is A factor kept the same in all groups or trials.

  1. Identify the investigation skill: Determine whether the question asks about a question, hypothesis, variable, data display, conclusion, or safety practice.
  2. Use the evidence: Keeping other conditions the same makes it easier to identify the effect of the independent variable.
  3. Check the design: Confirm that the procedure is fair, measurements are recorded clearly, and the conclusion matches the evidence.

Keeping other conditions the same makes it easier to identify the effect of the independent variable.

4. QuestionMultiple choice

In an investigation of fertilizer and plant height, what is the dependent variable?

Please select an answer first.

Correct answer: D

The correct answer is The height or growth of the plants.

  1. Identify the investigation skill: Determine whether the question asks about a question, hypothesis, variable, data display, conclusion, or safety practice.
  2. Use the evidence: Plant height is the outcome measured to see whether fertilizer has an effect.
  3. Check the design: Confirm that the procedure is fair, measurements are recorded clearly, and the conclusion matches the evidence.

Plant height is the outcome measured to see whether fertilizer has an effect.

5. QuestionMultiple choice

In an investigation of ramp height and cart speed, what is the independent variable?

Please select an answer first.

Correct answer: A

The correct answer is The height of the ramp.

  1. Identify the investigation skill: Determine whether the question asks about a question, hypothesis, variable, data display, conclusion, or safety practice.
  2. Use the evidence: Ramp height is the factor deliberately changed.
  3. Check the design: Confirm that the procedure is fair, measurements are recorded clearly, and the conclusion matches the evidence.

Ramp height is the factor deliberately changed.

6. QuestionMultiple choice

Why should a fair test change only one main variable at a time?

Please select an answer first.

Correct answer: B

The correct answer is It helps show which variable caused a change in the results..

  1. Identify the investigation skill: Determine whether the question asks about a question, hypothesis, variable, data display, conclusion, or safety practice.
  2. Use the evidence: Changing one variable makes the relationship between cause and outcome clearer.
  3. Check the design: Confirm that the procedure is fair, measurements are recorded clearly, and the conclusion matches the evidence.

Changing one variable makes the relationship between cause and outcome clearer.

7. QuestionMultiple choice

What is a control group or control condition?

Please select an answer first.

Correct answer: C

The correct answer is A comparison condition that does not receive the experimental change.

  1. Identify the investigation skill: Determine whether the question asks about a question, hypothesis, variable, data display, conclusion, or safety practice.
  2. Use the evidence: A control provides a baseline for comparing the effect of the independent variable.
  3. Check the design: Confirm that the procedure is fair, measurements are recorded clearly, and the conclusion matches the evidence.

A control provides a baseline for comparing the effect of the independent variable.

8. QuestionMultiple choice

Why should experimental groups be as similar as possible at the beginning?

Please select an answer first.

Correct answer: D

The correct answer is Similar starting conditions make the comparison more fair..

  1. Identify the investigation skill: Determine whether the question asks about a question, hypothesis, variable, data display, conclusion, or safety practice.
  2. Use the evidence: A fair comparison reduces other explanations for differences in the results.
  3. Check the design: Confirm that the procedure is fair, measurements are recorded clearly, and the conclusion matches the evidence.

A fair comparison reduces other explanations for differences in the results.

9. QuestionMultiple choice

A student tests paper towel absorbency using different sheet sizes. What should the student control?

Please select an answer first.

Correct answer: A

The correct answer is Use the same sheet size for each brand..

  1. Identify the investigation skill: Determine whether the question asks about a question, hypothesis, variable, data display, conclusion, or safety practice.
  2. Use the evidence: Keeping sheet size the same prevents it from becoming an alternative cause of the result.
  3. Check the design: Confirm that the procedure is fair, measurements are recorded clearly, and the conclusion matches the evidence.

Keeping sheet size the same prevents it from becoming an alternative cause of the result.

10. QuestionMultiple choice

What can happen if a scientist changes two variables at once?

Please select an answer first.

Correct answer: B

The correct answer is It may be difficult to tell which variable caused the result..

  1. Identify the investigation skill: Determine whether the question asks about a question, hypothesis, variable, data display, conclusion, or safety practice.
  2. Use the evidence: Multiple changes make it harder to identify the cause of an observed effect.
  3. Check the design: Confirm that the procedure is fair, measurements are recorded clearly, and the conclusion matches the evidence.

Multiple changes make it harder to identify the cause of an observed effect.
