Are you good at tossing a Frisbee? Have you ever wondered how a Frisbee is able to fly through the air so well? If you can throw a perfect, arcing curve, right on target, you have already trained your arm on the aerodynamics of Frisbee flight! In this science activity, you will investigate how the angle at which you throw the Frisbee affects its flight's direction and distance. Next time you are out tossing a Frisbee, this little lesson in aerodynamics may help make your throws be even… Read more

The Birthday Paradox

Science Fair Project Idea

Scientific Method

This project shows how mathematical probability sometimes contradicts our intuition. Despite the fact that there are 365 days in a year, if you survey a random group of just 23 people there is a 50:50 chance that two of them will have the same birthday. Don't believe it? Try this project and see for yourself. Read more

The Taylor Swift Challenge

Science Fair Project Idea

Scientific Method

Taylor Swift famously got in shape for her three-hour-long Eras Tour concerts by singing all 40+ songs...while running on a treadmill! Have you ever tried running while singing at the top of your lungs? How hard do you think it is? In this science project you will measure the impact talking and singing have on a group of volunteer runners. Is anyone in better shape than Taylor Swift? Read more

Have you ever wondered what keeps you in your seat when you are riding a giant loop-de-loop roller coaster? Surprisingly, it is not the seat belt! You are kept in your seat because of something called centripetal force. Centripetal force actually does much more than make a ride on a roller coaster's loop possible — it keeps a satellite in orbit and you in your bicycle when taking a tight curve! In this science activity, you will use marbles and Jell-O® to investigate centripetal… Read more

Think Fast!

Science Fair Project Idea

Scientific Method

Are you a piano player or a video gamer? Then you might have a quick reaction time that can come in handy while playing sports. Find out how to measure your reaction time and compare it to your friends and family with this fun experiment. Read more

Tornadoes

Science Fair Project Idea

Scientific Method

Tornadoes are a very destructive weather phenomenon that is very hard to predict. Certain weather conditions can indicate if a tornado is likely to occur, but the path that the tornado will take is completely unpredictable. Storm chasers are people who chase tornadoes and try to capture them on film or video. They often have a sense of predicting where and when a tornado will strike, but the best images are also due to a bit of luck and survival instinct. Even though tornadoes are… Read more

Tough Beans: Which Cooking Liquids Slow Softening the Most?

Science Fair Project Idea

Scientific Method

OK, spill the beans, what's your favorite bean-rich food? Burritos? Chili? Or maybe you prefer the spicy Indian stew of lentils, known as dal? But what about fried tofu? Soymilk? Or peanut butter and jelly sandwiches? Did you know those foods come from beans as well? Beans are important to the diets of many people, and in this cooking and food science fair project, you'll learn how the liquid that beans are cooked in affects how quickly or slowly they soften.
