Science Fair Project Idea
thumbnail Spicy fried tofu. It's a delicious and savory main dish at many Asian restaurants. Stab a golden-brown piece, bite into it, and the juice inside rushes out, filling your mouth with rich flavors. Continue eating and you find the texture is very chewy and meat-like. Did you ever wonder how those white blocks of tofu you see in grocery stores are transformed into the chewy little sponges packed with flavorful juices you see in Asian restaurants? Try this cooking and food science fair project to… Read more

Science Fair Project Idea
When you open a can of green beans, have you ever wondered why the beans are not mushy, or more like a puree? Canning requires boiling the beans for a long period of time to kill bacteria, so why don't the beans fall apart into small pieces? Some fruits and vegetables—like cherries, apples, potatoes, sweet potatoes, beets, carrots, beans, cauliflower, and tomatoes—have the ability to undergo hardening, or firming of their plant tissues. A special enzyme, called pectin methyl… Read more

Science Fair Project Idea
When you think of successful inventions from the 1900's that have dramatically changed how people live, what comes to mind? The car? Radio? TV? The computer? What about the microwave oven? You might not remember a time when microwave ovens were not a standard part of most kitchens, but your parents or grandparents probably do. They can remember when heating leftovers took a good 30 minutes in a traditional oven. Or thawing a food from the freezer meant leaving it in the refrigerator overnight.… Read more

Science Fair Project Idea
thumbnail Watching professional racing-car drivers compete can be thrilling. The high speeds that racing cars can reach — up to 200 miles per hour (mph) and more! — put some unique demands on the vehicles. For example, to withstand high temperatures, the tires must be inflated with nitrogen gas, instead of air as with normal car tires. This enables the drivers to have better control over steering their cars as they race around the track. In this sports science project, you will inflate… 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
