In this science fair project, paint color pie slices onto a wheel and spin the wheel on an electric drill. See how colors add together to make new colors. The Science Buddies project ideas are set up consistently beginning with an...

Heart rates can be determined by the amount of physical activity your body is engaging in. The more physically active you are, the faster your heart beats. You can measure the rate your heart is beating by taking your pulse. This science...

The majority of video games are sedentary, meaning done in one position, but there is an increasing trend toward video games where the players are physically active. Whether or not these type of video games can be considered exercise is...

Thinking about improving your sports performance? Want to help friends and family make the most of their physical fitness activities? One factor to consider is food. Whether you realize it or not, what you eat does change your body. It...

Yo-yo's are a fun toy and there is nothing simpler than a string wrapped between two connected disks. But there's a lot of physics that makes a yo-yo work. In this science fair project, learn more about how and why a yo-yo works. You...

If you have ever had to adjust to a new time zone, you have noticed that it takes a while before you start to feel normal again. By shifting your sleep and activity schedule, you have altered the pattern of your body's circadian rhythms....

A great Science Fair project that involves analyzing your cat's behavior and designing toys that will be stimulating both physically and mentally. The Science Buddies project ideas are set up consistently beginning with an abstract,...

When you are craving an ice cold drink of soda, the last thing you want is to be stuck with a bunch of soda cans at room temperature. This fun science experiment sends you on a discovery to find the fastest way to cool soda with...

Hold onto your hats. In this science fair project, you will make a device that sends a film canister across the room with a small chemical explosion. The energy for the explosion is derived from the combustion of ethanol. You will...

In this science fair project, use an infrared thermometer to measure the temperature of differently colored paper exposed to sunlight, and calculate energy emission using the Stefan-Boltzmann equation. Find discussion questions, a list...

Check out this fun science fair project about the physics of musical sound production. Here you will make musical instruments with drinking straws, one for each note on a one-octave major scale. You will figure out the right lengths for...

Has anyone ever told you that you have a magnetic personality? Have you ever heard that opposites attract? These common phrases are both based on the properties of magnets and magnetic electricity. In this science fair project, learn how...

In this science fair project, measure the "lift" of a set of balloons and track how it changes over time as the helium escapes from the balloons. The Science Buddies project ideas are set up consistently beginning with an abstract,...

Physical activity is needed for maintaining normal bone strength and mass. But whether physical stress on finger bones during development leads to an increase in finger length, is something you will discover in this project not by...

If the discipline, precision, and power of martial arts is your bag, try this project out for size. You won't be sparring with any opponent other than a swinging kick bag, but you'll learn a few powerful lessons about the physics of...

If you ever seen a magician float an object in the air, you might think that levitation is just a magic trick, but the truth is you can use an invisible physical force to levitate a magnet. Try this simple, week-long science project to...

Kids love to ride the swings at the playground. The back-and-forth motion of a swing demonstrates the physics of a pendulum. In this experiment, you will investigate the factors that affect the speed and duration of a pendulum's swing.

This project is an experiment in classical physics. You'll be following in Galileo's footsteps, and investigating Newton's laws of motion, using a metronome as your timing device. This resource will help you get a firm understanding of...

This project is an experiment in classical physics. You'll be following in Galileo's footsteps, and investigating Newton's laws of motion, but you'll be taking advantage of modern video recording technology to make your measurements. The...
