Science experiments lesson 29: The scientific method and fair tests · Set 202 · 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.🔬 In the scientific method, which step number is “draw a conclusion”?

3. 3.🛟 Which of these is a safe habit? (a) mixing random liquids (b) putting things in mouth (c) tying back long hair (d) working with no adult
