Multiple Choice

Science is a way of understanding the natural world through observation, experimentation, and evidence-based explanations. In this section, you'll explore how scientific ideas are developed and tested. Based on this, which of the following best describes science?

• A collection of facts that never change

• A way of understanding the natural world through observation and evidence

• A set of opinions about the world

• A list of rules to follow

Multiple Choice

Which of the following is NOT a step in the scientific method?

• Observation

• Hypothesis

• Experiment

• Prediction

Multiple Choice

What does each letter in the CER framework stand for, and what does each component mean?

• Claim: A statement that answers the question; Evidence: Observations, data, and research that support the claim; Reasoning: Scientific principle that shows how the evidence supports the claim.

• Claim: A hypothesis; Evidence: A guess; Reasoning: An opinion.

• Claim: A question; Evidence: An answer; Reasoning: A summary.

• Claim: A summary; Evidence: A conclusion; Reasoning: A prediction.

Multiple Choice

Why is it important to use the CER (Claim-Evidence-Reasoning) framework in science?

• It helps organize scientific explanations and communicate ideas clearly.

• It makes experiments more fun.

• It allows you to skip collecting data.

• It is required for all science tests.

Fill in the Blanks

A logical explanation that connects evidence to the claim using scientific principles is called

.

Multiple Select

Select all the statements that are examples of evidence in a scientific explanation.

• Plants in full sunlight grew an average of 10 cm taller than plants in the shade over 4 weeks.

• Sunlight provides energy for photosynthesis.

• Plants grow faster in sunlight than in the shade.

• Measurements show that plant height increased by 10 cm in sunlight.

Multiple Choice

Which of the following statements best represents reasoning in the CER framework?

• Sunlight provides the energy plants need for photosynthesis, which helps them grow. Therefore, the taller growth in sunlight supports the claim.

• Plants grow faster in sunlight than in the shade.

• In an experiment, plants in full sunlight grew an average of 10 cm taller than plants in the shade over 4 weeks.

• Plants are green because of chlorophyll.

Multiple Choice

What claim is made about Green Lakes State Park in relation to the study of early Earth conditions?

• It is a popular tourist destination.

• It is an ideal natural laboratory for studying early Earth conditions and the origins of life.

• It is the largest lake in the region.

• It is known for its recreational activities.

Multiple Choice

Which of the following best describes a controlled experiment?

• An experiment with multiple variables changed at once

• An experiment with no control group

• An experiment with one group under known conditions and another with one variable changed

• An experiment with random outcomes

Multiple Choice

What evidence supports the claim that Green Lakes State Park is an ideal place to study early Earth conditions?

• The lake is very shallow and mixes frequently.

• Fayetteville Green Lake is meromictic, creating a permanently anoxic bottom layer where unique microorganisms live.

• The park is located in a desert region.

• The lake is used for fishing competitions.

Multiple Choice

In Redi's experiment, what was the manipulated variable?
