Science Fair Project Idea

Engineering Design Process

Do you like winter sports like sledding or skiing? Check out this winter-themed engineering project to build your own miniature "ski lift." Use it to transport small objects from one place to another, just like a real ski lift transports skiers from the bottom of a mountain to the top. Read more

Have you ever played with your own shadow? It is fascinating how it follows your every move. But why do you not see your shadow every day? Why is your shadow very long sometimes, and other times very short? In this activity, you will make your own shadow puppet and explore how you can change the shape or size of its shadow. If you like, you can even create your own shadow play! Read more

Measure the Frequency Response of a Paper Speaker

Science Fair Project Idea

Scientific Method

Can you build a working speaker out of paper? How does a speaker's ability to play low or high-pitched notes depend on its size? Explore the science of sound in this project as you build and test your own speakers in order to answer these questions! Read more

Rocket Science: How High Can You Send a Payload?

Science Fair Project Idea

Scientific Method

Rockets are definitively an engineering challenge. These amazing gravity-defying machines have lifted test material, people, and even animals into space. Feel like building one yourself? In this science project, you will transform a water bottle into an aerodynamic bottle rocket with two compartments, one for the fuel and one for a payload. You will then test how well it performs when lifting mass vertically up into the air. Ready, set, soar! 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

Using a Laser to Measure the Speed of Light in Gelatin

Science Fair Project Idea

Scientific Method

Think it takes expensive, sophisticated equipment to measure the speed of light? Think again! Outfit yourself with a simple handheld laser pointer, a protractor, and gelatin, and you're ready to get started. Read more

Have you seen a rainbow in the sky after a rain shower? How many colors were there? A rainbow is often described as having seven colors: red, orange, yellow, green, blue, indigo and violet, but you might spot a rainbow and see fewer colors. Or you might see more than seven! It can be tricky to count the colors in a rainbow, because they all blend together so seamlessly. Want to see for yourself? In this activity you will explore the physics of light and create your own mini-rainbows. How many… Read more

Investigate the Motion of a Pendulum

Science Fair Project Idea

Scientific Method

"Swing me higher, Mommy, higher!" 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, also called an oscillating motion. You can even use your phone and a sensor app to record your pendulum's movement and determine its period of oscillation. Read more

Do you remember your last parade, party, or fair? You might have been surrounded by sounds of all kinds: fireworks, music, and, maybe even the famous (or infamous) sound of kazoos. A kazoo is a very simple musical instrument, made up of a hollow pipe with a hole in it. They may be simple, but these little noisemakers are a great way to explore sound. In this activity you'll be investigating how kazoos work by building your own! Read more

Measuring the Speed of 'Light' with a Microwave Oven

Science Fair Project Idea

Scientific Method

Did you know that you can measure the speed of light using a microwave oven, some egg white, and a ruler? Find out how with this cool kitchen science project thanks to Mr. Nick Hood, a science teacher in Fife, Scotland. Read more
