Science Fair Project Idea
thumbnail 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 (or e-textiles for short) 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 clothing so it can do… Read more

- Less Details
Time Required Average (6-10 days)
Prerequisites Familiarity with basic electronics concepts like positive and negative terminals as well as open and closed circuits will be helpful for this science project. Students with no experience building circuits may want to try the simpler but thematically simlar project: [# ProjectIdea Name="Elec_p077" Value="HtmlAnchor" #].
Material Availability This science project requires special LEDs designed for use with e-textiles, and it will be much easier to do with a soldering iron. See the Materials and Equipment list for details.
Cost Average ($40 - $80)
Safety Soldering irons can get extremely hot and burn your skin if you touch them accidentally. They can also cause fires if left unattended. Adult supervision is required when using a soldering iron, especially if you are not familiar with using one. Science Buddies recommends using lead-free solder, especially in homes with pets and small children.
Science Fair Project Idea
thumbnail Have you ever tried to ride your bike up a flight of stairs? Vehicles with wheels are great at traveling on paved roads or flat ground, but when it comes to stairs or uneven ground in the woods, wheels are not always such a great option. Inspired by real-life all-terrain robots, in this engineering project you will design and build a LEGO® robot that can travel over bumpy ground, through your yard, or even up a stack of textbooks — and almost anything else you can think of!

Science Fair Project Idea
If you like playing electric guitar, this could be a cool project for you. Have you ever wondered how an electric guitar works? In this project you'll wind one or more of your own electric guitar pickups and test them out in an inexpensive electric guitar. How will the sound change with the number of turns you use in the coil? Or with the strength of the magnets you use? Read more

Time Required Average (6-10 days)
Prerequisites To do this project, you'll need an inexpensive electric guitar in which to install and test the pickup(s) you make. You'll also need a guitar amplifier.
Material Availability Readily available
Cost Very High (over $150)
Safety Adult supervision required when potting (melted wax-coating) the pickup
Science Fair Project Idea
thumbnail Do you like making things with play dough or modeling clay? Wouldn't it be cool if you could add a bunch of lights to your creations? In this science project, you will make play dough that conducts electricity, and we will introduce you to some new types of circuits so you can add more lights to your artistic creations. This science project is the second in a three-part series on "squishy circuits," which can all be done with the same materials. We recommend doing the science projects in order. Read more
Elec_p074
+ More Details
- Less Details
Time Required Average (6-10 days)
Prerequisites You should understand the Introduction material in Make Your Play Dough Light Up, Buzz, & Move!—the first science project in the "Electric Play Dough" series—before doing this science project.
Material Availability This science project requires a Squishy Circuits Kit and ingredients to make conductive and insulating play dough. See the Materials and Equipment list for details.
Cost Low ($20 - $50)
Safety Ask for an adult's help when using the stove to make the conductive play dough. Never connect the battery pack's terminals directly to each other; this is called a short circuit and can make the batteries and wires get very hot. Do not connect the LEDs directly to the battery pack without using play dough; this will burn out the LEDs.

thumbnail Are you an artist, or do you enjoy the process of making art? What kind of art do you create? Do only humans make art? Not all the time. Robots can create art, too. Robots can be programmed and "taught" to do all kinds of things, such as delivering medications to hospital patients or putting together a car on an assembly line. The Vangobot™, shown in the video below, paints pictures with brushes and paint, and in a distinct, unique style - just like a human artist. Watch… Read more

Time Required Long (2-4 weeks)
Prerequisites Programming experience is needed to do this project.
Material Availability

This robotics engineering project requires that you purchase VEX® robotics materials. See the Materials tab for a suggestion of some VEX® parts to use. With a little problem-solving, you may be able to substitute another robotics platform.

The RobotC software needed to program the VEX system is Windows based. If you are using an Apple computer you will need to use visualization software such as VirtualBox or VMware®.

Cost Very High (over $150)
Safety Use caution with tools when assembling the robot. Minor injury is possible.
Science Fair Project Idea
thumbnail 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

thumbnail 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.

thumbnail Have you ever seen clothing with built-in lights? This might sound like something out of a science-fiction movie, but electronic textiles (or e-textiles for short) 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 up, respond to sound, or even serve medical purposes… Read more

thumbnail Have you ever seen butterflies fluttering around outside, gliding through the air and landing on flowers? While they are delicate and fragile, butterflies are actually excellent flyers. They are so good, in fact, that scientists at Harvard University studied butterfly wing shapes as an inspiration for building a miniature flying robot. In this science project, you will do your own version of the Harvard scientists' experiment to measure the flight performance of butterfly wings. Read more
