Science experiments lesson 29: The scientific method and fair tests · Set 725 · 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.📝 What should you do if the result does not match your hypothesis? (a) change the numbers (b) hide the result (c) report it honestly (d) give up science
2. 2.⚖️ Fair test — which kind of ball bounces highest? True or false: the person dropping is kept the same. (a) True (b) False
3. 3.🔍 Which is the odd one out? (a) mixing random liquids (b) touching a hot iron (c) washing hands afterwards (d) working with no adult
4. 4.🛟 What should you do with leftover materials at the end? (a) clean up safely (b) taste them (c) hide them (d) leave them out
