What you do (Find the experiment, use the idea): 1. Read the question and find its experiment. 2. Use that experiment’s idea — density, dissolving, capillary action, light bending, air pressure, push-back, air resistance or condensation. 3. For a fair-test question, find what is changed, kept the same and measured. 4. For a safety question, choose what keeps everyone safe.
