Looking for ideas for a science experiments? Here are several ideas that use materials easily found in your house. A couple of them might require a trip to the grocery store or pharmacy, but mostly you can just raid the garage, kitchen or medicine chest for the ingredients. Many experiments you will want to do OUTSIDE. Each one will give you directions as well as suggest websites and books to help you understand what science is at work during the experiment.
