Science Fair Project Idea
thumbnail 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

thumbnail Have you ever looked up into the sky and seen not a bird, not a plane, but a hot-air balloon? They are definitely amazing and fun to watch! Do you think they are all the same size? Does size affect how long the hot-air balloon can fly? In this science fair project, you will launch hot-air balloons, powered by a toaster, and see how the size of the balloon affects its flight.

Science Fair Project Idea
thumbnail Advertisements for high-tech sports gear or the latest and greatest outdoor material promise lighter and stronger products every season. Is it a scam? How can engineers keep creating materials that are both lighter and stronger than anything known so far? The answer is in the nanoscale! Using nanotechnology, scientists can play around with the detailed structure of matter, leading to a whole new range of materials, some with amazing qualities. In this science project, you will get a glimpse… Read more

Science Fair Project Idea
thumbnail When your parents were kids, they probably wore polyester. Static cling was a major household issue! Now everybody wears cotton, which does not get static cling nearly as much. Why are some materials more susceptible to static cling than others? Investigate how well different materials produce static electricity by making a homemade electroscope and testing it out in this science project. Read more

Science Fair Project Idea
thumbnail How do astronomers collect stardust? They design and build satellites that are launched into space to collect particles on specially designed panels. Satellites can be sent to orbit around an object of interest: a planet, moon, or comet. In this experiment, you can build your own mini satellite and use it to collect some pretend stellar debris. If you simulate an asteroid impact, how much stellar dust will your satellite collect? Will placing your satellite at different "orbital" distances from… Read more

Science Fair Project Idea
thumbnail Where do you get your best ideas? At school with your friends? When you are out for a bike ride? Over 2,200 years ago, a scientist named Archimedes got one of his best ideas when he sat down in his bath. Eureka! He went running through the streets without even bothering with his clothes. What was he so excited about? He had discovered that when objects, like his body, are placed in water, water is pushed out of the way. Have you noticed that, too? The weight of the water that is pushed out of… Read more
