Science experiments lesson 29: The scientific method and fair tests · Set 235 · 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) give up science (b) report it honestly (c) hide the result (d) change the numbers
2. 2.🛟 Which of these is a safe habit? (a) putting things in mouth (b) running with glassware (c) asking an adult first (d) touching a hot iron
