Engineer an LED Night-Light

Science Fair Project Idea

Engineering Design Process

Night-lights can be found in many homes; you might even have one in your bedroom! Using a night-light is a great way to avoid stubbing your toe on furniture during a midnight trip to the bathroom. In this fun engineering project, you will design and build your own night-light. You will need to build the circuit, but you will also need to think about the physical design of the product. Most people probably do not want an ugly, bare circuit board sitting around their house. Can you make a… Read more

LED Traffic Glove: Build a Safety Device to Direct Traffic

Science Fair Project Idea

Scientific Method

From traffic safety lights to neon signs, lights have a way of getting peoples' attention. So it makes sense that if a person wants to get attention, wearing clothing with built-in lights might help. These types of clothing, called electronic textiles (e-textiles for short), or wearable electronics, already exist. Instead of using hard surfaces for circuits (like inside your computer or cell phone), e-textiles weave electrical parts like batteries, wires, and lights directly into wearable… Read more

Dance Mania: Build Your Own Dance Pad!

Science Fair Project Idea

Scientific Method

It's fun to host and attend parties. You can meet your friends, watch movies, and eat party food. Another thing that people like to do at parties is dance to music. Dancing is great exercise and just makes people happy. What if at the next party you attend, you could do your science fair project? Doesn't sound like a good idea? Well, in this electricity and electronics science fair project, you will make a dance pad that flashes lights when you step on it. Have your friends test it out for you.… 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

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

Build a Wearable Device Using an Arduino to Keep Astronauts Safe on Mars

Science Fair Project Idea

Engineering Design Process

Astronauts on Mars missions must be protected from hazardous environments, like steep cliffs, rocky terrain, and extreme temperature variations. How can geofencing help? In this project, you will design a system that uses geofencing technology coupled with biosensors to ensure astronaut safety. The system will create a virtual boundary around astronauts, providing alerts if they approach dangerous areas or leave designated safe zones, or if their vital signs fall below a certain threshold. Can… Read more

Water Drops and Sparks! Experimenting with a Kelvin Electrostatic Generator

Science Fair Project Idea

Scientific Method

Water is an interesting thing. We drink it, swim in it, and wash ourselves with it. We can get energy from water by damming it and sending it through a turbine. But did you know that we can use the natural electrical charges present in water and a Kelvin electrostatic generator to create sparks? You can even use a Kelvin electrostatic generator to temporarily light a bulb! Now that is one bright idea! 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

Wire Wilt: How Light-Emitting Diodes Fade As Temperature Increases

Science Fair Project Idea

Scientific Method

What's your favorite thing to do on the hottest day of the year? Dip your toes in an icy river? Hang out by the pool? Retreat to a cool basement? Lie motionless in the shade? You're probably not too eager to move around and put out a lot of energy, like mowing the lawn in the mid-afternoon sun. Well, you're not the only one. In this electronics science fair project, you'll find out that some semiconductor devices, like light-emitting diodes (or LEDs), act the same way. As their internal… Read more

Smart Medicine Cabinet: Build a Sensor That Reminds Patients When to Take Medication

Science Fair Project Idea

Scientific Method

Have you ever had to take prescription medicine to get over an illness? To get better, it is important to take the medication in the proper manner and at the proper time. Wouldn't it be cool if there were a tool or piece of automated equipment that held your medicine and reminded you to take it? A tool that would know when you picked up the bottle and took your medicine? Building a smart medicine cabinet is what this science project is all about! Read more
