Science experiments lesson 29: The scientific method and fair tests · Set 221 · 40 questions

What you do (Ask, guess, test, see, say): 1. Ask a question that an experiment can test. 2. Make a hypothesis: “I think … because …”. 3. Plan a fair test — change one thing, keep the rest the same, decide what to measure — then do it with an adult. 4. Observe and record, then draw a conclusion and share it honestly.

25. 25.⚖️ Why do we change only one thing in a fair test? (a) to know what caused it (b) to make it fun (c) to finish faster (d) to use less paper
