Shed Light on Electric Generators: Do More Coils Generate More Electricity?

Science Fair Project Idea

Scientific Method

The electricity in your home probably comes from a power plant, but did you know that you can actually generate your own electricity? Wondering what it would take to light up a small light? This is your chance! In this electronics science project, you will build your own electric generator and investigate how to light up not just one, but two lights. Read more

Solid Motor Rocket Propulsion

Science Fair Project Idea

Scientific Method

What does it take to launch a robot to Mars or for a satellite to explore our outer solar system? In this project you will explore the physics of a rocket as you predict its performance, launch it, and measure the actual results. This is rocket science! Read more

Stealthy Shapes: How to Make an Aircraft Invisible to Radar

Science Fair Project Idea

Scientific Method

Have you ever dreamed about becoming invisible? Or about making something else invisible, like the mess all over your room? Invisibility may sound like the stuff of science fiction (remember Star Trek's "Cloaking Device"?), but in reality, military vehicles, like planes and ships, can be made less observable, or even invisible, to different detection methods—like radar, sonar, or infrared sensors—by using stealth technology. In this engineering science fair project, you'll find out… Read more

Supercooling Water and Snap Freezing

Science Fair Project Idea

Scientific Method

Can water remain liquid below its normal freezing point? If it does, that water is supercool(-ed). This project shows you a method for supercooling water. You can test water from different sources to see whether or not it can be supercooled. Read more

Take a Musical Step Back in Time: Make Your Own Phonograph from Everyday Items

Science Fair Project Idea

Scientific Method

Don't you just love listening to music? In the 1980s, people listened to music on the Sony® Walkman®. Now, people listen to their favorite tunes on MP3 players and on their Apple® iPhonesTM. But listening to music on devices actually started in the late 1800s and early 1900s. In those days, people would gather around their phonograph to listen to their favorite tunes—people were just as amazed with the phonograph as you would be to handle an iPhone. In this physics science… Read more

Testing the Accuracy of Eyewitness Testimony

Science Fair Project Idea

Scientific Method

Think back to the last time you went to the grocery store. How well can you describe the person who was ahead of you in the check-out line? How many details do you remember about the person? How accurate do you think your memory is? Here is a project to investigate the accuracy of people's observations during everyday life. Read more

The Reasons for the Seasons

Science Fair Project Idea

Scientific Method

Do you live someplace where you get to experience the full glory of all four seasons? If so, you know well the heady blossoms and dramatic skies of spring; the long, sun-drenched days of summer; the trees shaking in crimson and gold in fall; and the sparkling, brittle snows of winter. But you might not know why we have these seasons, over and over again, in a cycle as predictable as the rising and setting of the Sun. The reasons for the seasons are surprising and have to do with Earth's tilt… Read more

The Science Behind Tsunamis: Study the Effect of Water Depth on Wave Velocity

Science Fair Project Idea

Scientific Method

A tsunami is a series of waves made in a body of water, like the ocean, that can cause serious destruction when they hit the coastline. In deep water, a wave can be just a few feet high and travel very fast. As it nears the coastline, and moves into shallower water, tsunamis usually slow down, but the wave height can grow to 100 feet! In this ocean science project, you will model a tsunami and investigate how wave velocity (speed) depends on water depth. Does it match the mathematical equation… Read more

Students simulate the spread of a virus such as HIV through a population by "sharing" (but not drinking) the water in a plastic cup with several classmates. Although invisible, the water in a few of the cups has already be tainted with the "virus" (sodium carbonate). After all the students have shared their liquids, the contents of the cups are tested for the virus with phenolphthalein, a chemical that causes a striking color change in the presence of sodium carbonate.… Read more
