Kitchen Chemistry Experiments Test Worksheet

Science experiments lesson 20: Part 2 test: kitchen chemistry and life · Set 511 · 40 questions

What you do (Find the experiment, use the idea): 1. Read the question and find its experiment. 2. Use that experiment’s idea — acid and base, indicator colours, chemical change, what seeds and yeast need, transpiration, crystals or filtering. 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.
