Science experiments lesson 29: The scientific method and fair tests · Set 316 · 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.True or false: wiping up spills at once is a safe habit. (a) True (b) False
2. 2.⚖️ Fair test — which kind of ball bounces highest? Which of these is what we measure? (a) the drop height (b) bounce height (c) the person dropping (d) the floor surface
