Science experiments lesson 29: The scientific method and fair tests · Set 564 · 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.

1. 1.⚖️ Fair test — which kind of ball bounces highest? Which of these is the one thing we change? (a) the drop height (b) the kind of ball (c) bounce height (d) the floor surface
