1. QuestionMultiple choice

In an experiment, a student changes the amount of fertilizer and measures plant height. What is the independent variable?

Please select an answer first.

Correct answer: A

The correct answer is The amount of fertilizer.

  1. Identify the task: Read the question and determine whether it asks for language, mathematics, reading evidence, science reasoning, or test strategy.
  2. Apply the skill: The independent variable is the factor deliberately changed by the researcher.
  3. Check the choice: Confirm that the selected answer addresses the question and is supported by the information provided.

The independent variable is the factor deliberately changed by the researcher.

2. QuestionMultiple choice

A graph shows temperature rising as sunlight exposure increases. What relationship is shown?

Please select an answer first.

Correct answer: B

The correct answer is A positive association.

  1. Identify the task: Read the question and determine whether it asks for language, mathematics, reading evidence, science reasoning, or test strategy.
  2. Apply the skill: Both variables increase together, indicating a positive association.
  3. Check the choice: Confirm that the selected answer addresses the question and is supported by the information provided.

Both variables increase together, indicating a positive association.

3. QuestionMultiple choice

Why should an experiment include repeated trials?

Please select an answer first.

Correct answer: C

The correct answer is Repeated trials improve confidence that the result is not caused by random variation.

  1. Identify the task: Read the question and determine whether it asks for language, mathematics, reading evidence, science reasoning, or test strategy.
  2. Apply the skill: Repeated measurements help reveal consistent patterns and reduce the effect of chance.
  3. Check the choice: Confirm that the selected answer addresses the question and is supported by the information provided.

Repeated measurements help reveal consistent patterns and reduce the effect of chance.

4. QuestionMultiple choice

A student concludes that a new light causes faster plant growth after testing only one plant. What is the main limitation?

Please select an answer first.

Correct answer: D

The correct answer is The sample size is too small to support a reliable conclusion.

  1. Identify the task: Read the question and determine whether it asks for language, mathematics, reading evidence, science reasoning, or test strategy.
  2. Apply the skill: One plant does not provide enough data to generalize the result confidently.
  3. Check the choice: Confirm that the selected answer addresses the question and is supported by the information provided.

One plant does not provide enough data to generalize the result confidently.

5. QuestionMultiple choice

Which statement describes a control group?

Please select an answer first.

Correct answer: A

The correct answer is A group kept under normal conditions for comparison.

  1. Identify the task: Read the question and determine whether it asks for language, mathematics, reading evidence, science reasoning, or test strategy.
  2. Apply the skill: The control group provides a baseline for judging the treatment effect.
  3. Check the choice: Confirm that the selected answer addresses the question and is supported by the information provided.

The control group provides a baseline for judging the treatment effect.

6. QuestionMultiple choice

If a model predicts that increasing pressure raises boiling temperature, which observation would support the model?

Please select an answer first.

Correct answer: B

The correct answer is Water boils at a higher temperature in the higher-pressure condition.

  1. Identify the task: Read the question and determine whether it asks for language, mathematics, reading evidence, science reasoning, or test strategy.
  2. Apply the skill: The observation matches the model's predicted relationship.
  3. Check the choice: Confirm that the selected answer addresses the question and is supported by the information provided.

The observation matches the model's predicted relationship.

7. QuestionMultiple choice

Which measurement is most useful for comparing the density of two samples?

Please select an answer first.

Correct answer: C

The correct answer is Mass divided by volume for each sample.

  1. Identify the task: Read the question and determine whether it asks for language, mathematics, reading evidence, science reasoning, or test strategy.
  2. Apply the skill: Density is calculated as mass per unit volume.
  3. Check the choice: Confirm that the selected answer addresses the question and is supported by the information provided.

Density is calculated as mass per unit volume.

8. QuestionMultiple choice

A food web loses most of its decomposers. What is the most likely effect?

Please select an answer first.

Correct answer: D

The correct answer is Nutrients would return to the ecosystem more slowly.

  1. Identify the task: Read the question and determine whether it asks for language, mathematics, reading evidence, science reasoning, or test strategy.
  2. Apply the skill: Decomposers break down material and return nutrients to the environment.
  3. Check the choice: Confirm that the selected answer addresses the question and is supported by the information provided.

Decomposers break down material and return nutrients to the environment.

9. QuestionMultiple choice

Which evidence best supports the claim that a region is becoming warmer over time?

Please select an answer first.

Correct answer: A

The correct answer is The long-term average temperature increases across multiple decades.

  1. Identify the task: Read the question and determine whether it asks for language, mathematics, reading evidence, science reasoning, or test strategy.
  2. Apply the skill: A long-term trend is stronger evidence than a single event.
  3. Check the choice: Confirm that the selected answer addresses the question and is supported by the information provided.

A long-term trend is stronger evidence than a single event.

10. QuestionMultiple choice

A researcher finds an unexpected data point far from the others. What should happen first?

Please select an answer first.

Correct answer: B

The correct answer is Check the measurement and recording process before deciding how to treat it.

  1. Identify the task: Read the question and determine whether it asks for language, mathematics, reading evidence, science reasoning, or test strategy.
  2. Apply the skill: An outlier may result from an error or a real condition, so it should be investigated.
  3. Check the choice: Confirm that the selected answer addresses the question and is supported by the information provided.

An outlier may result from an error or a real condition, so it should be investigated.
