Science experiments lesson 29: The scientific method and fair tests · Set 91 · 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.

21. 21.🔁 Why should we repeat an experiment a few times? (a) to waste time (b) to get tired (c) to check results agree (d) to change answers
22. 22.🔬 In the scientific method, which step number is “make a hypothesis”?
23. 23.⚖️ Why do we change only one thing in a fair test? (a) to use less paper (b) to make it fun (c) to know what caused it (d) to finish faster
