Have you ever wondered how to create art with moving parts using nothing but cardboard, a few skewers, and some craft supplies? In this fun STEM activity, you will build an automaton, a machine that makes parts appear and disappear, move up and down, spin in circles, or all of these together. The instructions will show you how to build a moving caterpillar, but you can use your imagination to build any other animal or object you want! Read more

The Physics of Catapult Projectile Motion

Science Fair Project Idea

Scientific Method

In physics class, you have probably rolled your eyes at some point after being assigned a "projectile motion" homework problem where you use equations to predict how a ball will move through the air. This experiment will show you just how fun that problem can be by using a real catapult to launch a ball and videotaping it as it flies along its path. Then, you will analyze the video and compare it to what the equations predicted. If you have ever wondered if those equations in your physics… Read more

Build a Remotely Operated Vehicle (ROV) for Underwater Exploration

Science Fair Project Idea

Engineering Design Process

Have you ever wanted to explore cold or murky water? What about places where it could be dangerous or difficult for humans to swim? Remotely operated vehicles (ROVs) allow humans to take pictures, videos, and scientific samples of underwater life and habitats while safely operating the vehicle from a boat or from shore. In this project you will design and build your own small ROV that you can test in a bathtub, pool, or nearby body of water. Read more

What if you could take a single liquid, and change it into a rainbow of colors without using food dye. You can! In this activity you will use red cabbage to make what is called an indicator solution. Indicator solutions can change colors depending on what you add to them. In this case adding something acidic (like lemon juice) will change it to one color while adding something basic (like bleach) will change it to another. Try and see how many colors you can make using different household… Read more

Build an RC Boat

Science Fair Project Idea

Engineering Design Process

Do you like playing with radio-controlled (RC) toys like cars, planes, and boats? What if you could build and customize your own? In this engineering project, you will learn how to build your own RC boat using an Arduino and a plastic food storage container. Read more

How to Build an X-ray Machine

Science Fair Project Idea

Scientific Method

When you have your X-rays taken at the dentist's or doctor's office, do you ever wonder how the X-ray machine works? Or better yet, how you could make one yourself to use for experiments? This how-to guide provides detailed instructions for high school students and adult do-it-yourself (DIY) enthusiasts to construct and use a homemade X-ray machine safely. Read more

The egg-drop project is a classic and time-honored tradition in many science classes. The goal is usually to build a device that can protect an egg when dropped from a high location. This activity puts a twist on the classic project, motivated by real-world advances in space exploration. Can you build a reusable egg-drop lander that can survive repeated falls from the same height? Try this activity and find out Read more

Build an Ultrasonic Levitator

Science Fair Project Idea

Engineering Design Process

It's not magic; it's science! Build your own acoustic levitator to make objects float in midair using invisible sound waves. Read more

Have you ever watched a fireworks show and wondered how all the different colors — amazing reds, yellows, oranges, blues, purples, greens, and more — are made? The color, or colors, that a firework makes depends on what color-producing chemicals are in the firework. These chemicals are various metal salts that burn when the firework goes off, and burning the metals is what makes the colors. Different metals give off different, specific colors. In this science activity, you will get… Read more

Marble Roller Coaster: Converting Potential Energy to Kinetic Energy

Science Fair Project Idea

Scientific Method

If you'd like to investigate the physics of amusement park rides, then this project is for you. You'll build a roller coaster track for marbles using foam pipe insulation and masking tape, and see how much the marble's potential energy at the beginning of the track is converted to kinetic energy at various points along the track.
