Science Fair Project Idea
Electric paint is a fun way to include a circuit with lights in an art project, but it presents a challenge not found in traditional electronic circuits. What happens if you change the length or width of your strokes of paint, such as by painting longer, curvier lines or using a thicker brush? Could this affect the electrical properties of your circuit? Try this project to find out! Read more

Science Fair Project Idea
Along with its many other interesting properties, water has the ability to absorb a lot of heat energy, while only experiencing a relatively small change in temperature. One way this property affects us directly is that our bodies don't change temperature rapidly on hot or cold days, since we are made up of mostly water. In this chemistry-with-an-electronics-flair science fair project, you will determine how the temperature of a small volume of water changes as you add precise amounts of heat… Read more

Science Fair Project Idea
In the animal kingdom, many different critters use whiskers to help them find their way around in the dark, through murky waters, or even to help them hunt prey. Whiskers can be very useful when the animals cannot rely on sight. Did you know that you can also build a robot that uses "whiskers" to find its way around? This project will show you how to build a simple robot that uses whiskers as "bump sensors" to help the robot detect when it is about to bump into an obstacle, so it can turn… Read more

Science Fair Project Idea
Global warming, climate change, melting ice caps—these are all big events that have an impact our environment. What can we do to help reduce the impact? We can reduce, reuse, and recycle. What can cities do to help? Cities can eliminate waste by saving energy. Cities around the world are switching from incandescent traffic signals to LED traffic signals to save energy and money. That's because LEDs are more efficient than incandescent lamps, which means that LEDs produce more light… Read more

Do not look directly at the LED when it is in operation and be sure to wear your sunglasses. Be sure to wear safety goggles when operating power tools.
Science Fair Project Idea
Objects that glow in the dark hold a special place in the imagination of both children and adults. The lights go out at night, but these odd things refuse to disappear. Where does the light come from? Do they work in any climate? In this science fair project, you will build an electronic device that measures the light given off by luminescent materials. The device will be used to study how temperature affects luminescence. Read more

Time Required Long (2-4 weeks)
Prerequisites A familiarity with basic chemistry is required. Also, some experience with electronics would be helpful. Although the circuit is fairly straightforward, especially if you use the kit, this is a DIY ("do-it-yourself") project that will call for some creative problem solving on your part.
Material Availability Any phosphorescent material will work for this project. If you want to use super-bright phosphorescent paints, they are available online. See the Materials & Equipment list for more information.
Cost High ($100 - $150)
Safety Use caution when using the drill or knife. Wear safety goggles when using the drill.
Science Fair Project Idea
Light interacts with matter in a variety of ways—it can be absorbed, reflected, refracted (bent), and scattered. The scattering of light explains why the sky is blue, why milk is white, and why the Mississippi River is called "The Big Muddy." In this biochemistry science fair project, you will make an electronic device to measure the amount of scattered light in milk. You will also use the device to track the activity of protease (a type of enzyme) in pineapple juice, based on its ability… Read more

Science Fair Project Idea
A nice hot cup of tea sure can wake and warm you up in the morning. In this science fair project, you will investigate the chemistry of tea. The longer you steep a tea bag in hot water, the stronger the tea will be. But how does the strength of the tea change with longer brewing time? In this food science project, you will make a very simple electronic device to measure the strength of tea. The device will determine how strong the tea is by measuring the amount of light the tea absorbs. Read more
