Manipulating Magnets to Improve Generator Output

Science Fair Project Idea

Scientific Method

The electricity you use to power everyday devices is generated by electrical generators. These fascinating and powerful machines rely on magnets to function. Though they might seem extremely complicated, once you finish this science project, you will understand how, why, and when they generate electricity. You will build your own generator, make small changes in how exactly the magnets are placed, and test when moving magnets generate electricity. Read more

Build Your Own Super-sensitive Electric Field Detector

Science Fair Project Idea

Scientific Method

Wouldn't it be nice to avoid those nasty electric shocks you get after you have walked around on carpet and then touch a doorknob? These shocks are caused by static electricity. In this project, you will build a super-sensitive charge detector to investigate the electric fields created by static electricity. The detector can sense invisible electric fields before you touch something and get zapped, so try this project to avoid the shock of shocks! Read more

Build a Model Planetary Lander with micro:bit

Science Fair Project Idea

Engineering Design Process

How do you make a spacecraft land safely on the Moon or another planet like Mars? It probably helps to know how far away the ground is so you can deploy landing gear, activate a parachute, or fire thrusters to help slow down. In this project you will build your own "lander" vehicle with a sensor that can measure distance to the ground, allowing you to program outputs like blinking lights or an audible alarm. 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

Abracadabra! Levitating with Eddy Currents!

Science Fair Project Idea

Scientific Method

Did you know that not all trains run on tracks? Some of the world's fastest trains are magnetic levitation trains (maglev). This means that the carriage of the train is suspended over the rails with no support, but only with magnetic fields! There is a physical explanation for magnetic levitation, and if you would like to learn more about magnetism and current, this is a science fair project that you must try! Read more

Rubbing Up Against Static Electricity

Science Fair Project Idea

Scientific Method

A tried and true balloon activity is to rub a balloon on your head to make your hair stand up. How does the rubbing build up static electricity? Do this experiment to see if the number of rubs makes a difference. Read more

How to Make a Dimmer Switch with a Pencil

Science Fair Project Idea

Scientific Method

Dimmer switches let us control the brightness of a light, anywhere from completely off to full brightness. This can be nice when you want to set the brightness "just right," as opposed to a regular light switch that only lets you turn a light on or off. It turns out that you can make a dimmer switch out of an everyday object—a pencil! Try this project to find out how a dimmer switch can control the brightness of a light. Read more

Design Your Own Smart LED Lighting System

Science Fair Project Idea

Engineering Design Process

Have you ever had lights turn on automatically when you walked into a room? Have you turned on a light with your voice instead of a switch? Maybe you have even seen lights that change color depending on temperature, ambient sounds, or how close you are to something. In this project you will design and build your own smart LED lighting system that can change colors and react to various things in the room. The possibilities are endless! Check out this page for more LED science projects. Read more

Monitor Plant Health with a Color Sensor

Science Fair Project Idea

Engineering Design Process

Do you have a garden or houseplants? What about living on or a near a farm? How often do you check your plants' leaves for discoloration? What if you could build a robot to check for you, and warn you if your plants are getting sick? In this project you will learn to use a color sensor to identify different colors on leaves, which can give you a warning about problems like pests, diseases, or nutrient deficiency. Get ready to automate your gardening! Read more

Paper Circuits: Make Electrifying Art

Science Fair Project Idea

Scientific Method

"Paper circuits" are a fun way to mix electronics and art by adding lights directly to a painting or drawing. These lights need a battery to power them, and typically you would use wires to connect them. In paper circuits, though, many materials can be substituted as "wire," including special types of paint, ink, and even aluminum foil. There are also different options for what type of battery you can use. Which materials do you think will work best? Try this project to find out! Read more
