Science Fair Project Idea
thumbnail You've probably noticed the colorful patterns "reflecting" from the shiny surface of a CD disk. What you are seeing is actually diffraction of white light, and the rainbows of color are diffraction patterns. In this project you'll learn about how diffraction patterns are generated, and you'll find out how you can use a laser pointer and a protractor to measure the microscopic spacing of data tracks on a CD.

Science Fair Project Idea
thumbnail Can you imagine designing and building a space telescope the size of a tennis court? Believe it or not, that is someone's job! Engineers are hard at work on the James Webb Space Telescope, or JWST. This telescope has the potential to enable astronomers to see light from when the Universe was first formed. No one knows what amazing discoveries this might lead to. However, to make the telescope work properly, engineers have to overcome a lot of challenges. In this science project, you can… Read more

Do you love to listen to your MP3 player while you're exercising, or listen to songs on the Internet? The relatively recent development of MP3 technology has made it possible to take a stack of CD's and store them on a device no bigger than a deck of cards. How does the MP3 format squeeze all those CD's down so well, and can it go too far? Try this music science fair project to find out! Read more

Science Fair Project Idea
thumbnail Jumping discs can be a fun toy to play with, and with their sudden POP!, they can even be a good way to startle people who have never heard them before. Jumping discs use a neat trick to jump. They are made of two different types of metal, and these metals expand when they heat up (or shrink when they cool down), but not by exactly the same amount. In this science project you will explore how temperature affects the reactions of your jumping discs— and how to get the timing right if you… Read more

Time Required Average (6-10 days)
Prerequisites None
Material Availability This project requires buying bimetallic jumping discs. See the Materials and Equipment list for details.
Cost Very Low (under $20)
Safety Adult supervision is required during use of a hair dryer as a heat source. Hair dryers can cause burns or fires if used improperly and should not be operated by small children alone.

Do not use the jumping discs on surfaces that are fragile or can be easily scratched.

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

Science Fair Project Idea
thumbnail If you have ever been shot with a rubber band then you know it has energy in it, enough energy to smack you in the arm and cause a sting! But just how much energy does a rubber band have? In this experiment you will find out how the stretching of a rubber band affects the amount of energy that springs out of it. Read more

Science Fair Project Idea
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.

Safety Adult supervision is required. Use caution with the hot toaster. A hot toaster is a potential fire hazard.
Science Fair Project Idea
thumbnail You might know that we are able to get free energy from the Sun, the wind, and water, but did you know we can get free energy from Earth itself? The temperature inside of Earth can reach 9,000°F—that kind of heat can be used to make a lot of energy here on the surface! This source of energy is called geothermal energy and it is all about taking advantage of the heat within Earth. So try this science fair project out and find out how to use the heat that lies beneath your feet! Read more

Science Fair Project Idea
thumbnail The movement of satellites is intriguing, but how do they orbit the way they do? Aerospace engineers run calculations and set up computer models to help them predict how satellites move in space, but in this astronomy science project, you will create a physical model with marbles, clay, and a cookie sheet to help you study how satellites move in space and learn from your observations.

Can you remember all of your ABC's? Computers need to "remember" letters too. Every time we use a computer to write a story, the computer needs to "remember" the letters in the story by saving them to the computer's memory as a file. In this experiment find out how much memory it takes for the computer to "remember" a series of letters. Read more
