Electric Play Dough Project 3: Light Up Your Sculptures!
Science Fair Project Idea
Scientific Method
Have you tried our first and second play dough circuits projects? Are you a master circuit artist, ready to try something even bigger and better? Try this project to see if you can build a three-dimensional light-up sculpture. Read more
Color Mixing with Red, Green, & Blue LEDs
Science Fair Project Idea
Scientific Method
This is a good project for someone who is interested in both electronics and color vision. The equipment needed is on the expensive side, but if you continue studying electronics, you can use it again and again. Read more
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
Where There Is Charge, There Can Be Sparks!
Science Fair Project Idea
Scientific Method
Have you ever gotten a shock touching a doorknob after walking across a carpet? Static charge is responsible for that shock. Wouldn't it be cool to save up and store all of that charge in a homemade jar? It would almost be like storing lightning. This science project will show you how to do that. Read more
Rock On! Recording Digital Data with Magnets
Science Fair Project Idea
Scientific Method
This is a straightforward project that shows you how data can be digitized and stored on magnetic recording media. You'll learn how alpha-numeric characters are digitized, and you'll use bar magnets to represent the individual data "bits." You'll also learn about how much information can be stored in a small space (recording density), and how magnetic data can be erased. 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
Upstairs, Downstairs: Turning on a Light from Two Places
Science Fair Project Idea
Scientific Method
Maybe somewhere in your home there's a long hallway or a stairway with a light that you can turn on from either end. It's a nice convenience, but did you ever wonder how it's wired up to work that way? The goal of this project is to build a similar circuit with switches, flashlight batteries and a flashlight bulb (obviously, household circuits are not safe to experiment with). You'll need to understand the difference between connections made in series and connections made in parallel in an… Read more
How Does LED Brightness Vary with Current?
Science Fair Project Idea
Scientific Method
LEDs (light-emitting diodes) are electronic components that convert a portion of the electrical energy flowing through them into light. How does the intensity of the light produced vary with the current flowing through the LED? To find out, you'll build some simple circuits to vary the current flowing an LED. You'll also build a simple light-to-voltage converter circuit to measure LED output. Read more
How Do You Know Where You Are Without GPS? Dead Reckoning and Inertial Navigation
Science Fair Project Idea
Engineering Design Process
Put a meter stick on the ground. Starting at one end of the stick, close your eyes and try to walk exactly one meter. Open your eyes. How close were you? Now try it again with five, ten, or twenty meters. Does it get harder as the distance gets bigger? Without an outside reference from your visual system, it's quite difficult to know exactly how far you've gone! Electronic navigation systems face the same problem. Without an external reference like the global positioning system (GPS), it's very… 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
