Claim: What is the scientist claiming about how the seeds are dispersed?
Evidence: What observations support this claim?
Reasoning: Explain how the evidence supports the claim.
Scenario 2: Two identical plants were placed in different locations. Plant A was placed in a sunny window, and Plant B was placed in a dark closet. After a week, Plant A was taller and greener than Plant B.
Claim: What is a claim you can make about what plants need to grow?
Evidence: What observations support this claim?
Reasoning: Explain how the evidence supports the claim.
Scenario 3: A student heated a block of ice in a beaker. The ice melted into water, and then the water boiled and turned into steam.
Claim: What is a claim you can make about the effect of heat on the state of matter?
Evidence: What observations support this claim?
Reasoning: Explain how the evidence supports the claim.
