Grade 6 · Science · Lesson 6

Write Claims Supported by Evidence

After you run a fair test and collect reliable data, the next job is to say what the data means. Scientists do not just shout an opinion. They write a claim, then they back it up with evidence, then they explain the science rule that links the two together. This three-part structure — Claim, Evidence, Reasoning — is how every real scientific argument is built. Learn it once and you can write a strong conclusion for any experiment.

1Write a clear claim that answers a science question in one sentence
