1. QuestionMultiple choice

In an experiment testing how pH affects enzyme activity, what should be measured as the dependent variable?

Please select an answer first.

Correct answer: A

The correct answer is The rate of the enzyme reaction.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: The dependent variable is the response measured after pH is changed.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

The dependent variable is the response measured after pH is changed.

2. QuestionMultiple choice

Why should a scientific investigation include a clear operational definition?

Please select an answer first.

Correct answer: B

The correct answer is It explains exactly how a variable will be measured.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: Operational definitions make measurements consistent and repeatable.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

Operational definitions make measurements consistent and repeatable.

3. QuestionMultiple choice

A graph shows two variables increasing together. What is the most accurate conclusion without a controlled experiment?

Please select an answer first.

Correct answer: C

The correct answer is The variables are associated, but causation is not established.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: A relationship in observational data does not alone prove cause and effect.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

A relationship in observational data does not alone prove cause and effect.

4. QuestionMultiple choice

What is the purpose of uncertainty in a measurement?

Please select an answer first.

Correct answer: D

The correct answer is To communicate the range in which the measured value may lie.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: Uncertainty acknowledges limits in instruments and measurement procedures.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

Uncertainty acknowledges limits in instruments and measurement procedures.

5. QuestionMultiple choice

Which result is most likely an outlier?

Please select an answer first.

Correct answer: A

The correct answer is A measurement far from the other repeated measurements.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: An outlier is unusually distant from the main pattern and should be investigated.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

An outlier is unusually distant from the main pattern and should be investigated.

6. QuestionMultiple choice

An engineering design must reduce water use while keeping crop yield stable. Which is a useful criterion?

Please select an answer first.

Correct answer: B

The correct answer is The design lowers measured water use without lowering yield below a target.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: A criterion should be measurable and tied directly to the engineering goal.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

A criterion should be measurable and tied directly to the engineering goal.

7. QuestionMultiple choice

Why is peer review valuable in science?

Please select an answer first.

Correct answer: C

The correct answer is Other scientists can evaluate methods, evidence, and reasoning.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: Peer review can identify weaknesses and improve the reliability of published work.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

Peer review can identify weaknesses and improve the reliability of published work.

8. QuestionMultiple choice

A model predicts a population decline, but later data show growth. What is the best response?

Please select an answer first.

Correct answer: D

The correct answer is Review assumptions, update the model, and compare it with new data.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: Models are revised when evidence reveals that assumptions or parameters need improvement.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

Models are revised when evidence reveals that assumptions or parameters need improvement.

9. QuestionMultiple choice

A battery provides 12 joules of energy in 3 seconds. What is its average power?

Please select an answer first.

Correct answer: A

The correct answer is 44 watts.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: Power equals energy divided by time: 12 / 3 = 4 watts.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

Power equals energy divided by time: 12 / 3 = 4 watts.

10. QuestionMultiple choice

Which response best uses claim, evidence, and reasoning?

Please select an answer first.

Correct answer: B

The correct answer is The claim states a conclusion, data support it, and reasoning explains the scientific connection.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: A strong CER response connects a conclusion to relevant evidence and scientific principles.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

A strong CER response connects a conclusion to relevant evidence and scientific principles.
