Science Fair Project Idea
thumbnail Have you ever left your bike outside in the rain? If so, you might have discovered unpleasant surprises afterwards—reddish-brown patches, known as rust, and your wheels, brakes, and gears might have stopped working so smoothly. In this chemistry science fair project, you'll learn why rust, a type of corrosion, is a serious problem. You'll also discover that not all rains are the same! Find out which ones can speed up the rusting process. Read more

thumbnail Watching a spacecraft launch is an amazing experience. It is thrilling to see it lift off and escape Earth's gravity. Did you know that it takes a chemical reaction to get a spacecraft into space? Every time you see a one blast off, you are watching chemistry at work. In this chemistry science fair project, you will also get to blast an object into the air. You will not be using the same fuel that NASA uses for the rockets that launch their spacecrafts; instead, you will use two simple… Read more

thumbnail Hold onto your hats! In this science fair project, you will make a device that sends a film canister across the room with a small chemical explosion. The energy for the explosion is derived from the combustion of ethanol. You will determine the launch velocity of the canister, as well as devise ways to study changes in gas pressure and volume due to the explosion. This science fair project is sure to take your breath away! Read more

Science Fair Project Idea
You're at the high school football game and it's getting pretty chilly as the sun goes down. You're determined to keep cheering for your team, but your hands are freezing—have you ever tried hand warmers? The chemistry within these little packets is pretty cool. Hand warmers provide a unique and fun way to study the chemistry of crystal formation and heat generation. By pressing a button in a pouch, which contains a supercooled solution, you start a rapid exothermic (heat-producing)… Read more

Yeast contains an enzyme, called catalase, that acts as a catalyst for the reaction that breaks down hydrogen peroxide into oxygen and water (2H2O22H2O + O2). Safety note: oxygen is a highly reactive gas, adult supervision recommended for this project. For your background research, be sure that you understand substrate, catalyst, reaction rate, catalase, enzyme saturation and protein denaturation. Use a solution of 3% H2O2 for the substrate. Construct an apparatus that allows you to collect… Read more
