If you're looking for science fair project ideas you came to the right place! On this page you will find several ideas for cool science fair projects, for kids of all ages. These projects are particularly interesting because they have practical relevance in real life, and you can use common everyday materials to create them. These project ideas are mostly physics based. For the most part I have worked on these projects myself, and have included pictures for your benefit.
Make sure you have adult supervision and assistance, where required, when working on these projects.
Science Fair Project Ideas — Insulation Testing
This is one of the more practical science fair project ideas since it relates to insulation, which is a common material in home construction. I tested the insulation value of some common materials to see which one worked best. The pictures below show pictures of the basic set up I used.
The figure below shows three large yogurt containers with smaller cups inserted inside. In the space between cup and container (including the space underneath the cups) I placed insulation material. The first cup on the left has sawdust as insulation. The cup in the middle has leaves as insulation. The cup on the right has no insulation — this is the control which serves as a base reference used to compare the effectiveness of the insulation materials.

Inside the cups you place equal amounts of ice, by weight, from the same freezer. The goal is to see which cup slows down the melting of the ice the most. This tells you which insulation material works best.
After you have placed the ice inside the cups you can seal them. What I did was place a cardboard lid on the cups, and on top of the lids I placed insulation material (for those two cups where insulation material was used) — this way you have insulation all around. This set up allows you to easily check
