Have you ever wondered why it is harder to keep your balance with a heavy backpack on? Or why it is difficult to make a toddler's sippy cup tip over? Maybe you are the kind of person who wonders about circus balancing acts and would like to learn how to ride a bike on a rope. Or perhaps you want to know how to make your toy car less prone to toppling over when racing through a sharp curve. In this science activity, you will get to investigate balance using marshmallows, skewers, and… Read more

Do you know where your drinking water is coming from? Sure, it comes out of your faucet, but how does it get there? Drinking water all over the world originates from either surface waters—such as lakes, reservoirs, and rivers—or from underground sources, such as groundwater. But would you want to drink water straight from a river or lake? Probably not; they can be really dirty and muddy! To become clean and safe, this water first has to undergo several treatment processes; the first… Read more

Extreme Sounds: Lessons in a Noisy World

Science Fair Project Idea

Scientific Method

Can you hear me now . . . ? Just how loud does a sound have to be for us to hear it? And how loud is too loud for our ears? Learn to measure levels of sound in this project, and discover the amazing auditory range your ears can detect in the noisy world around you. If you have a smartphone handy, you can even do this project without purchasing any additional materials, by using your phone's sound sensor and a sensor app. Read more

Football Punting: Distance vs. Hang-time

Science Fair Project Idea

Scientific Method

When the punter is trying to hit the "coffin corner" (within the opposing team's 10-yard line), out of bounds, what is the best angle to kick the ball for correct distance and maximum "hang time?" (For more information on the physics involved, see: Gay, 2004, Chapters 4 and 5.) Read more

HAMing It Up with the Astronauts

Science Fair Project Idea

Scientific Method

Have you ever wished you could talk to an astronaut on board the International Space Station? You're probably thinking "yeah, like NASA would ever let you do that!" Actually, they will! The International Space Station (ISS) is equipped with its own HAM radio station. The ISS HAM radio station allows astronauts, cosmonauts, and space mission specialists from different nations who are on board the space station to talk to people back home on Earth. Anyone with an amateur radio license is… Read more

High-Speed Magnets: Exploring Faraday's Law and Lenz's Law

Science Fair Project Idea

Scientific Method

Safety Notes about Neodymium Magnets: Neodymium magnets are very strong. Adult supervision is recommended when using them. Be careful not to drop the magnets, and do not let them slam together or fall. They may pinch your fingers, crack, or shatter. Keep magnets away from small children, pets, credit cards, and pacemakers. In the Science Buddies project Human-Powered Energy, you can learn about the basics of magnetic induction, or how moving magnets can be used to generate an… Read more

How long do you think you could survive without drinking any water? Only three to four days! Your body needs water to function properly. We also rely on water for cooking, cleaning and many other activities. You might not think about getting enough water if you can get it easily by turning on your faucet. But what about areas that don't have a reliable water supply? In this activity you will learn about one creative way to collect water—from the air! Read more

Have you ever wondered how water droplets form on a window on a rainy day, why some bugs can mysteriously walk on water, or why you use soap to wash your hands? All of these things are related to the phenomenon called surface tension. In this activity you will learn how you can use surface tension to make a fish cut from a piece of paper seemingly swim around on its own! Read more

A popular science demonstration shows that when you overlap the pages of two phone books, they are nearly impossible to pull apart. Since most people do not have two phone books sitting around, we will show you how you can do the same experiment with sticky notes. Sticky notes are much smaller than phone books, so they should be easy to pull apart, right? Try this activity to find out! Read more

Have you ever wondered why rubbing a balloon or a blanket—or even a winter hat—on your head makes your hair stand up? The effect is due to static electricity, but how is the static electricity made, and why does it make your hair stand on end? Static electricity is the buildup of electrical charge in an object. Sometimes static electricity can suddenly discharge, such as when a bolt of lightning flashes through the sky. Other times, static electricity can cause objects to cling… Read more
