CER is how scientists explain results. Claim: your answer to the question. Evidence: the data or observations that support it. Reasoning: the science that connects your evidence to your claim. Fill each box (tap a sentence starter to begin), then build your paragraph.

A clear, one-sentence answer to the question. No "because" yet.
