Can You Change the Rate of a Chemical Reaction by Changing the Particle Size of the Reactants?

Science Fair Project Idea

Scientific Method

The ingredients in Alka-Seltzer® tablets undergo a chemical reaction that produces carbon dioxide gas as soon as the tablets hit water. Do you think you can cause the tablets to produce gas faster by breaking them into smaller pieces before dropping them in water? Find out for yourself with this project. Read more

Chemistry of Ice-Cream Making: Lowering the Freezing Point of Water

Science Fair Project Idea

Scientific Method

Have you ever made your own ice cream? If you have, you probably know that you need to get the ice cream mixture really cold to freeze it quickly. Ice cubes alone will not do the job, but if you add chemicals, such as salt or sugar, to the ice cubes that surround the ice cream container, the mixture gets cold enough to freeze. Why does that work? How does adding salt or sugar affect the freezing point of water? Find out with this ice-cold science project and use your results to make your own… Read more

Cold Pack Chemistry: Where Does the Heat Go?

Science Fair Project Idea

Scientific Method

Instant cold packs are popular with coaches and parents for treating minor bumps and bruises. The instant cold packs are not pre-cooled—you just squeeze the cold pack and its starts to get cold. So how does it work? In this chemistry science fair project, you will investigate the chemical reaction that occurs in instant cold packs. Read more

Colorful Chemistry Creations: Make Your Own Sun Print with Color and Sunlight!

Science Fair Project Idea

Scientific Method

You've probably heard of hand prints and fingerprints, but what about a Sunprint®?

Crazy Crystal Creations: How to Grow the Best and the Largest Crystals

Science Fair Project Idea

Scientific Method

Crystals come in all different shapes and sizes. However, the purest and cleanest crystals are usually also the ones that grow to be the largest in size. In this science fair project, you will compare the size and shape of crystals grown in three different temperature conditions: room temperature, in the refrigerator, and in an ice bath. With just water and borax, a household cleaning product, you can discover the best recrystallization method for growing large, pure crystals. Read more
