LED Dance Glove: Get the Party Started with Your Own Interactive Light Show

Science Fair Project Idea

Scientific Method

Have you ever seen clothing with built-in lights? This might sound like something out of a science-fiction movie, but electronic textiles (>e-textiles for short, also called wearable electronics or sewable circuits) really exist. Instead of using hard surfaces for circuits (like what goes inside your computer or cell phone), e-textiles weave electrical parts like batteries, wires, and lights directly into clothing that you can wear to make the clothing do fun, interesting things like light… Read more

Make a Pomodoro Study Clock

Science Fair Project Idea

Engineering Design Process

The Pomodoro technique is a popular study method consisting of alternating study sessions and breaks. In this engineering project you will build your own customized Pomodoro timer or clock using an Arduino. In addition to displaying the time, you can use your clock to display messages or get the user's attention using lights, sound, or even moving parts. Can you work more efficiently with a Pomodoro timer at your side? Build one and find out! Read more

Make Your Own Wireless Alarm System

Science Fair Project Idea

Engineering Design Process

Have you ever wished you could have an alarm to prevent your little brother or sister from sneaking into your room? How about an alarm to prevent someone from stealing your favorite toy or from taking cookies out of the cookie jar? In this project you will learn how to program your own customized, wireless alarm systems to send you alerts about whatever you want! Read more

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

Use Super-strong Magnets to Make a Simple Motor

Science Fair Project Idea

Scientific Method

In this science project, you will build what might be the world's simplest motor. It has just four basic parts: magnets, a battery, a screwdriver, and a short piece of wire. It takes only minutes to assemble, but it provides a wonderful device to explore how electricity and magnetism combine to produce a fast-spinning motor. Read more

Build a Reed Switch Motor

Science Fair Project Idea

Scientific Method

Motors are used in many things you find around your house, like your refrigerator, coffee maker, and even a lawn mower. In this electronics science fair project, you will get to build a simple motor, using a kit, and then test how the number of batteries (amount of voltage) used to power the motor affects its performance.

Build an Arduino Strobe Light for the Stroboscopic Effect

Science Fair Project Idea

Engineering Design Process

The Science Buddies project Build a Levitating Water Fountain with the Stroboscopic Effect shows you how to illuminate a dripping stream of water with a strobe light to make it look like the drops are hovering in mid-air. If you have not already, read the background section of that project and watch the following two videos. Make sure you understand frequency, period, and duty cycle before you proceed with this project. The project has you use a strobe light app on your phone. The advantage… Read more

Does Your Mobile Phone Radiate? Measuring Cell Phone Electromagnetic Radiation

Science Fair Project Idea

Scientific Method

Every day, no matter where you are, you will see people using their cell phones. People use their cell phones for more than just making calls though. They use them for texting and searching the Internet, too. But some health groups are concerned that using your cell phone too much can be hazardous to your health as it exposes your body to electromagnetic radiation. In this electricity and electronics science project, you will investigate how much radiation your cell phone emits when used… Read more
