Science experiments lesson 29: The scientific method and fair tests · Set 897 · 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.

2. 2.⚖️ Fair test — which kind of ball bounces highest? What do we do with “the person dropping”? (a) we measure it (b) we change it (c) we keep it the same
3. 3.🔍 Which is the odd one out? (a) wiping up spills at once (b) putting things in mouth (c) tying back long hair (d) asking an adult first
