Science experiments lesson 29: The scientific method and fair tests · Set 779 · 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) report it honestly (b) change the numbers (c) hide the result (d) give up science
