Homework Help: Science Experiments


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.

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


GaleScience [65] Science in Context [65]: 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 [66]?)
science-fair-discoverer-logo [67] Science Fair Discoverer: [67] This is a great way to find experiments that use common around-the-house items.  Search by asking where you want to begin:  In the recycling bin?  In the junk drawer?  In the yard? In the Kitchen? In the Bathroom?   When an experiment is selected, you will see a list of needed items and directions. (What’s my PIN [66]?)
