Ball Launcher Challenge

Science Fair Project Idea

Engineering Design Process

Try your hand at this engineering challenge. Can you build a "launcher" device to launch a ball as far as possible and a "receiver" to catch it? Building a receiver provides an extra twist to a traditional catapult project. Add to the challenge by using a limited set of materials to build your machine and calculate a score based on your throw distance and materials used. Read more

How Does Speed Affect Orbiting Altitude of Satellites?

Science Fair Project Idea

Scientific Method

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.

The Strength of an Electromagnet

Science Fair Project Idea

Scientific Method

You may be familiar with permanent magnets—the kind that hang on a refrigerator. But did you know that other magnets, called electromagnets, can be turned on and off? When turned on, electromagnets act just like permanent magnets, but if you turn them off, their magnetic properties disappear. Electromagnets are an important part of many electronic devices, like motors and loudspeakers. You can create an electromagnet with a simple coil of wire and a battery. In this project, you will… Read more

Squishy Robot Simulator

Science Fair Project Idea

Scientific Method

What do an octopus, an elephant's trunk, and an earthworm have in common? They are all squishy, bendable and flexible because they do not have any bones inside. You might not typically think of robots as "squishy," but scientists are increasingly trying to create soft robots that look and move like animals. In this project you will use a "soft robot simulator" to design and race your own squishy robots. Can you come up with the fastest design? Read more

Why Winglets?

Science Fair Project Idea

Scientific Method

Have you ever noticed how some jet planes have small, vertical projections as the tips of the wings? They're called winglets. What are they there for? Read more

Bottled-up Buoyancy

Science Fair Project Idea

Scientific Method

Do you dream about making deep, undersea voyages? Let this project take you 20,000 leagues under the sea! Investigate how submarines dive and surface by changing their buoyancy in this fun project. Read more

How the Strength of a Magnet Varies with Temperature

Science Fair Project Idea

Scientific Method

Physicists sometimes study matter under extreme conditions. For example, think of the emptiness of interstellar space vs. the unimaginable crush of pressure at the center of a neutron star, or an object dipped in liquid nitrogen vs. the tiles on the space shuttle during re-entry. Here's an experiment on permanent magnets in "extreme kitchen" conditions that you can try at home. Read more

Build a Solar-Powered Car

Science Fair Project Idea

Scientific Method

Do you want to build a solar-powered car? How about enter it in a competition and race it against other people's designs? If so, this is the project for you! These instructions will show you how to get started building a solar-powered car that you can enter in a science or engineering fair. No experience needed. If you want, you can even compete in the Junior Solar Sprint, a regional competition for solar-powered cars. Get more information about your regional competition. Are you a… Read more

The Effect of Bridge Design on Weight Bearing Capacity

Science Fair Project Idea

Scientific Method

Build model bridges and then deliberately destroy them? Who'd be crazy enough to try that? Read more

The Chills and Thrills of Roller-Coaster Hills

Science Fair Project Idea

Scientific Method

Think it's a good idea to stream music, watch videos, or check social media while doing homework? Are you a thrill-seeker? Well, this is the science fair project for you! What makes a ride so thrilling that people want to ride it over and over again even though it scares them? Is it the speed, the twists and turns, the vertical drops? In this science fair project, you will build and use an accelerometer to figure out what makes a roller-coaster ride worth standing in line for. Oh, and if Mom… Read more
