Science Fair Project Idea
Cake, cookies, pie, ice cream, hot chocolate, lemonade... Yum! What do all these delicious treats have in common? Sugar. In addition to providing sweetness, sugar adds bulk, flavor, and structure to foods. But is it necessary to add sugar to achieve sweetness? Can the same sweetness be achieved using sugar substitutes like artificial or natural sweeteners? In this project, you will test sugar and sugar substitutes and compare the sweetness of each in relation to sugar. In the end, your day will… Read more

Have you ever made your own ice cream? If you have, you probably surrounded the ice cream container with ice and rock salt to get the mixture cold enough to freeze. But why does that work? How does adding salt (or other substances) affect the freezing point of water? Find out with this ice-cold science project. Read more

Did you know that your body needs a certain amount of iron in order to stay healthy? Iron can be found in much of what you consume each day. Almond meal—frequently used in cookies—is just one example of an iron-rich food. However, only a small fraction of the iron in food gets absorbed by the body, partially because the body can only absorb dissolved iron. In this project, you will study whether the acidic environment in your stomach helps dissolve iron. You will use a color-based… Read more

The enormous task of cleaning up oil spills in oceans and seas has burdened industry, government, and environmentalists for decades. The cleanup is almost always difficult. It involves great amounts of time, resources, and money to remove the oil from the water, and the cleanup is often only partially successful. Today, however, scientists are coming to the rescue, developing a new technique that combines nanotechnology and magnetism. In this science project, you will test the proposed… Read more

Safety Neodymium magnets are very strong. Some have the capacity to interfere or reset pacemakers. Never put a neodymium magnet in your mouth. Always keep them away from computers, credit cards, and other magnetized objects.

Ferrofluids create stains on skin and other materials, so take appropriate measures to keep the fluid contained to the working area.

Science Fair Project Idea
You have probably heard about using renewable energy sources like wind and solar power to provide electricity to homes and buildings, as well as hybrid or fully electric cars that use less (or zero) gasoline. But what about solar-powered robots? As robots become more common, it is increasingly important to use "green" energy sources to power them. In this project, you will build and test a popular robot called a bristlebot — a tiny robot made using toothbrushes—that can operate on… Read more

Maple syrup is deliciously gooey and great on breakfast foods like pancakes and waffles. But it has another amazing property. It can be turned into maple candies with a range of textures, like sticky maple taffy or molded maple sugar candy. In this science fair project, you will investigate how the temperature that maple syrup is heated up to affects what type of maple syrup-based candies can be made. Read more

In baseball, coaches use hit charts to track the results of every hit each player makes, giving a measure of the player's performance. Have you ever wondered what things affect where a baseball goes when a player hits it with a bat? In this project you will set up an experiment to hit a ping pong ball in a controlled manner using a toy catapult, then learn about the physics of baseball by making your own hit chart. Read more
