Kitchen Chemistry for Families
Four famous kitchen experiments, done properly: a homemade lava lamp, oobleck, a baking soda volcano and invisible ink. Each one starts with a real question, works with things from your cupboard, and leaves your child able to explain what happened.
Grades K–2Science
Test It, Choose It: Materials
What is a spoon made of, and why isn't it made of paper? Children sort objects by material, test which materials keep the rain out and which keep the sun off, and choose the right material for a job. Kitchen, stationery and recycling-bin materials, no weather needed.
