Daniel tested how the angle of a ramp affects the distance a toy car travels after rolling down. He adjusted the ramp to different angles (10°, 20°, 30°) and measured how far the car traveled on a flat surface.

CER

Claim: A clear and concise statement that answers the question or problem.Evidence: Data and observations that support the claim, gathered from experiments or research. Reasoning: An explanation that connects the evidence to the claim, showing why the evidence supports the claim using scientific principles and knowledge.

Write a Claim, Evidence, Reasoning (CER) response for the question below.

How does the ramp angle affect the distance a toy car travels?

Emma investigates how different materials conduct heat by placing identical metal, glass, and plastic spoons in hot water and measuring the temperature at the end of each spoon after 5 minutes.

Reasoning: An explanation that connects the evidence to the claim, showing why the evidence supports the claim using scientific principles and knowledge.

Write a Claim, Evidence, Reasoning (CER) response for the question below.

Which material conducts heat most effectively?

Sofia tested how light bends when passing through different materials. She shined a laser beam at a 30° angle into glass, water, and air, measuring the angle of refraction (the angle at which the light exited each material).
