1. QuestionMultiple choice

Which question is testable through an investigation?

Please select an answer first.

Correct answer: A

The correct answer is How does the amount of sunlight affect the height of a bean plant?.

  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: A testable question identifies variables that can be measured, such as sunlight and plant height.
  3. Check the explanation: Compare the choice with the evidence. The best answer is How does the amount of sunlight affect the height of a bean plant?.

A testable question identifies variables that can be measured, such as sunlight and plant height.

2. QuestionMultiple choice

In an investigation of how water temperature affects dissolving time, what is the independent variable?

Please select an answer first.

Correct answer: B

The correct answer is The temperature of the water.

  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 independent variable is the factor the investigator changes, which is water temperature.
  3. Check the explanation: Compare the choice with the evidence. The best answer is The temperature of the water.

The independent variable is the factor the investigator changes, which is water temperature.

3. QuestionMultiple choice

Students test three types of soil using the same seed, container, water amount, and light. Why keep these conditions the same?

Please select an answer first.

Correct answer: C

The correct answer is To make the comparison between soil types fair..

  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: Keeping other variables constant helps show whether differences in growth are related to soil type.
  3. Check the explanation: Compare the choice with the evidence. The best answer is To make the comparison between soil types fair..

Keeping other variables constant helps show whether differences in growth are related to soil type.

4. QuestionMultiple choice

Why should a scientist repeat trials in an investigation?

Please select an answer first.

Correct answer: D

The correct answer is Repeated trials can make results more reliable..

  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: Repeated trials help identify patterns and reduce the effect of an unusual result or random error.
  3. Check the explanation: Compare the choice with the evidence. The best answer is Repeated trials can make results more reliable..

Repeated trials help identify patterns and reduce the effect of an unusual result or random error.

5. QuestionMultiple choice

A graph shows that a plant grew taller each week after it received more hours of light. What trend does the graph show?

Please select an answer first.

Correct answer: A

The correct answer is Plant height increased as light exposure increased..

  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 two measured quantities increase together in the described data, showing a positive trend.
  3. Check the explanation: Compare the choice with the evidence. The best answer is Plant height increased as light exposure increased..

The two measured quantities increase together in the described data, showing a positive trend.

6. QuestionMultiple choice

A student predicts that a heavier paper airplane will travel farther. The results show that the lighter plane traveled farther in every trial. What should the student do?

Please select an answer first.

Correct answer: B

The correct answer is Use the results as evidence and revise the conclusion..

  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: Scientific conclusions should be based on recorded evidence, even when the evidence does not support the original prediction.
  3. Check the explanation: Compare the choice with the evidence. The best answer is Use the results as evidence and revise the conclusion..

Scientific conclusions should be based on recorded evidence, even when the evidence does not support the original prediction.

7. QuestionMultiple choice

Students investigate whether different amounts of water affect plant growth. Which setup is fairest?

Please select an answer first.

Correct answer: C

The correct answer is Use the same type and size of plant with the same soil and light, changing only the amount of water..

  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: A fair test changes one independent variable while keeping other important conditions the same.
  3. Check the explanation: Compare the choice with the evidence. The best answer is Use the same type and size of plant with the same soil and light, changing only the amount of water..

A fair test changes one independent variable while keeping other important conditions the same.
