  3. Check the explanation: Make sure the selected answer fits the observation, model, data, or scientific principle in the question.

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

4. QuestionMultiple choice

Why should a student repeat trials in an investigation?

Please select an answer first.

Correct answer: D

The correct answer is Repeated trials help show a reliable pattern..

  1. Identify the science idea: Determine whether the question asks about matter, energy, life systems, Earth systems, data, evidence, or engineering.
  2. Use the evidence: Multiple trials can reduce the effect of unusual results and improve confidence in a pattern.
  3. Check the explanation: Make sure the selected answer fits the observation, model, data, or scientific principle in the question.

Multiple trials can reduce the effect of unusual results and improve confidence in a pattern.

5. QuestionMultiple choice

A data table shows that plants receiving more sunlight grew taller. Which graph is best for showing the pattern?

Please select an answer first.

Correct answer: A

The correct answer is A graph with sunlight amount on one axis and plant height on the other.

  1. Identify the science idea: Determine whether the question asks about matter, energy, life systems, Earth systems, data, evidence, or engineering.
  2. Use the evidence: A graph should compare the changed amount of sunlight with the measured plant height.
  3. Check the explanation: Make sure the selected answer fits the observation, model, data, or scientific principle in the question.

A graph should compare the changed amount of sunlight with the measured plant height.

6. QuestionMultiple choice

What is the purpose of a scientific model?

Please select an answer first.

Correct answer: B

The correct answer is To represent a system or process so it can be studied..

  1. Identify the science idea: Determine whether the question asks about matter, energy, life systems, Earth systems, data, evidence, or engineering.
  2. Use the evidence: A model represents important parts of a system and helps explain or predict behavior.
  3. Check the explanation: Make sure the selected answer fits the observation, model, data, or scientific principle in the question.

A model represents important parts of a system and helps explain or predict behavior.

7. QuestionMultiple choice

A team designs a bridge that must hold 20 books and use only 30 craft sticks. The limits are examples of what?

Please select an answer first.

Correct answer: C

The correct answer is Constraints.

  1. Identify the science idea: Determine whether the question asks about matter, energy, life systems, Earth systems, data, evidence, or engineering.
  2. Use the evidence: Constraints are limits that a design must meet.
