1. QuestionMultiple choice

A student tests three temperatures and records reaction times of 12, 8, and 5 seconds. Which temperature produced the fastest reaction?

Please select an answer first.

Correct answer: A

The correct answer is The temperature associated with 5 seconds.

  1. Read the task: Identify the passage, sentence, equation, chart, or scientific claim that the question asks you to analyze.
  2. Apply the strategy: The smallest time represents the fastest reaction.
  3. Check the answer: Compare the choice with the evidence or calculation and confirm that it answers the question directly.

The smallest time represents the fastest reaction.

2. QuestionMultiple choice

A scientist changes light intensity and measures algae growth. What is the independent variable?

Please select an answer first.

Correct answer: B

The correct answer is Light intensity.

  1. Read the task: Identify the passage, sentence, equation, chart, or scientific claim that the question asks you to analyze.
  2. Apply the strategy: The independent variable is the factor deliberately changed by the scientist.
  3. Check the answer: Compare the choice with the evidence or calculation and confirm that it answers the question directly.

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

3. QuestionMultiple choice

Why is a control group useful in an experiment?

Please select an answer first.

Correct answer: C

The correct answer is It provides a comparison for evaluating the treatment..

  1. Read the task: Identify the passage, sentence, equation, chart, or scientific claim that the question asks you to analyze.
  2. Apply the strategy: A control group helps show what happens without the experimental treatment.
  3. Check the answer: Compare the choice with the evidence or calculation and confirm that it answers the question directly.

A control group helps show what happens without the experimental treatment.

4. QuestionMultiple choice

What is the role of enzymes in many biological reactions?

Please select an answer first.

Correct answer: D

The correct answer is They speed up reactions without being used up..

  1. Read the task: Identify the passage, sentence, equation, chart, or scientific claim that the question asks you to analyze.
  2. Apply the strategy: Enzymes are catalysts that help reactions occur more efficiently while remaining available.
  3. Check the answer: Compare the choice with the evidence or calculation and confirm that it answers the question directly.

Enzymes are catalysts that help reactions occur more efficiently while remaining available.

5. QuestionMultiple choice

Which process releases usable energy from glucose in cells?

Please select an answer first.

Correct answer: A

The correct answer is Cellular respiration.

  1. Read the task: Identify the passage, sentence, equation, chart, or scientific claim that the question asks you to analyze.
  2. Apply the strategy: Cellular respiration breaks down glucose and transfers energy to ATP.
  3. Check the answer: Compare the choice with the evidence or calculation and confirm that it answers the question directly.

Cellular respiration breaks down glucose and transfers energy to ATP.

6. QuestionMultiple choice

A car moving at constant speed travels around a curve. What changes?

Please select an answer first.

Correct answer: B

The correct answer is Its velocity changes because its direction changes..

  1. Read the task: Identify the passage, sentence, equation, chart, or scientific claim that the question asks you to analyze.
  2. Apply the strategy: Velocity includes direction, so turning changes velocity even when speed stays constant.
  3. Check the answer: Compare the choice with the evidence or calculation and confirm that it answers the question directly.

Velocity includes direction, so turning changes velocity even when speed stays constant.

7. QuestionMultiple choice

Which evidence supports conservation of energy in a roller coaster system?

Please select an answer first.

Correct answer: C

The correct answer is Potential energy decreases while kinetic energy increases as the car descends..

  1. Read the task: Identify the passage, sentence, equation, chart, or scientific claim that the question asks you to analyze.
  2. Apply the strategy: Energy can transfer between potential and kinetic forms while the total is conserved in an ideal system.
  3. Check the answer: Compare the choice with the evidence or calculation and confirm that it answers the question directly.

Energy can transfer between potential and kinetic forms while the total is conserved in an ideal system.

8. QuestionMultiple choice

Why can an increase in carbon dioxide affect ocean water?

Please select an answer first.

Correct answer: D

The correct answer is Carbon dioxide can dissolve and change ocean chemistry..

  1. Read the task: Identify the passage, sentence, equation, chart, or scientific claim that the question asks you to analyze.
  2. Apply the strategy: Dissolved carbon dioxide can form carbonic acid and alter ocean chemistry.
  3. Check the answer: Compare the choice with the evidence or calculation and confirm that it answers the question directly.

Dissolved carbon dioxide can form carbonic acid and alter ocean chemistry.

9. QuestionMultiple choice
