1. QuestionMultiple choice

A data table shows that seedlings given more light grew taller. What claim is supported?

Please select an answer first.

Correct answer: A

The correct answer is The amount of light affected seedling growth in this test.

  1. Identify the science idea: Decide whether the question is about matter, energy, living systems, Earth systems, design, or evidence.
  2. Use the evidence: The data support a claim about the relationship between light and growth in this investigation.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

The data support a claim about the relationship between light and growth in this investigation.

2. QuestionMultiple choice

Which graph is best for showing temperature changes over seven days?

Please select an answer first.

Correct answer: B

The correct answer is A line graph.

  1. Identify the science idea: Decide whether the question is about matter, energy, living systems, Earth systems, design, or evidence.
  2. Use the evidence: A line graph shows how a measured quantity changes across an ordered period of time.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

A line graph shows how a measured quantity changes across an ordered period of time.

3. QuestionMultiple choice

What is evidence?

Please select an answer first.

Correct answer: C

The correct answer is Observations or data used to support a claim.

  1. Identify the science idea: Decide whether the question is about matter, energy, living systems, Earth systems, design, or evidence.
  2. Use the evidence: Evidence comes from observations, measurements, or other information that supports a conclusion.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

Evidence comes from observations, measurements, or other information that supports a conclusion.

4. QuestionMultiple choice

Which observation is most useful when comparing two habitats?

Please select an answer first.

Correct answer: D

The correct answer is The number and types of organisms found in each habitat.

  1. Identify the science idea: Decide whether the question is about matter, energy, living systems, Earth systems, design, or evidence.
  2. Use the evidence: Recording organisms and their types provides relevant evidence about habitat differences.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

Recording organisms and their types provides relevant evidence about habitat differences.

5. QuestionMultiple choice

How can people help protect a local ecosystem?

Please select an answer first.

Correct answer: A

The correct answer is Reduce pollution and protect native habitats.

  1. Identify the science idea: Decide whether the question is about matter, energy, living systems, Earth systems, design, or evidence.
  2. Use the evidence: Reducing pollution and preserving habitats supports healthy ecosystems.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

Reducing pollution and preserving habitats supports healthy ecosystems.

6. QuestionMultiple choice

What may happen when too much fertilizer enters a pond?

Please select an answer first.

Correct answer: B

The correct answer is Excess nutrients can cause algae to grow and reduce oxygen.

  1. Identify the science idea: Decide whether the question is about matter, energy, living systems, Earth systems, design, or evidence.
  2. Use the evidence: Excess nutrients can cause algal growth that changes water conditions and lowers available oxygen.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

Excess nutrients can cause algal growth that changes water conditions and lowers available oxygen.

7. QuestionMultiple choice

Why are decomposers important to a food web?

Please select an answer first.

Correct answer: C

The correct answer is They return nutrients to soil and water.

  1. Identify the science idea: Decide whether the question is about matter, energy, living systems, Earth systems, design, or evidence.
  2. Use the evidence: Decomposers recycle matter so nutrients can be used again by producers.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

Decomposers recycle matter so nutrients can be used again by producers.

8. QuestionMultiple choice

A town replaces a grassy field with pavement. Which change is most likely during heavy rain?

Please select an answer first.

Correct answer: D

The correct answer is More water runs over the surface instead of soaking into soil.

  1. Identify the science idea: Decide whether the question is about matter, energy, living systems, Earth systems, design, or evidence.
  2. Use the evidence: Pavement reduces infiltration and can increase surface runoff.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

Pavement reduces infiltration and can increase surface runoff.

9. QuestionMultiple choice

Which conclusion is supported by repeated observations of birds visiting the same tree each morning?

Please select an answer first.

Correct answer: A

The correct answer is The tree may provide a useful food or shelter resource.

  1. Identify the science idea: Decide whether the question is about matter, energy, living systems, Earth systems, design, or evidence.
  2. Use the evidence: Repeated visits suggest the tree provides a resource, although more evidence may be needed to identify which one.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

Repeated visits suggest the tree provides a resource, although more evidence may be needed to identify which one.

10. QuestionMultiple choice

Why should a scientific conclusion match the data collected?

Please select an answer first.

Correct answer: B

The correct answer is The conclusion should be supported by the evidence.

  1. Identify the science idea: Decide whether the question is about matter, energy, living systems, Earth systems, design, or evidence.
  2. Use the evidence: A conclusion is stronger when it directly explains the pattern shown by the collected evidence.
  3. Check the claim: Make sure the answer matches the observation, model, data, or situation described.

A conclusion is stronger when it directly explains the pattern shown by the collected evidence.
