Looking for an idea for a science project? Here are several science experiment 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 experiment will give you directions as well as suggest websites and books that will help you explain what science is at work during the experiment.

Websites:

Here are some websites that have great step-by-step directions and photographs for planning a great science project.

Databases:

GaleScience Science in Context: This is a database you can look at with your IndyPL Library Card Number and PIN to get Science Experiment ideas and to do background research once you choose a subject. (What’s my PIN?)
ExperimentCentral Experiment Central is a set of experiment encyclopedias you can look at in the Gale Virtual Library. You will need your IndyPL Library Card Number and PIN to open these. (What’s my PIN?) A great resource for tracking down a science experiment idea!
