Science Fair Project Idea
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

Science Fair Project Idea
How easy is it for you to walk along and follow a line that is painted on the ground? Simple, right? You might be able to follow a line without giving it much thought, but how could a robot do that? In this project, you will build your own automatic line-following robot that can race around a track that you create. This technology has plenty of real-world applications—maybe one day you could help design self-driving cars! Read more

Science Fair Project Idea
Every day, we produce a lot of sewage (wastewater full of feces and urine). In fact, it adds up to 6.4 trillion liters of urine alone produced worldwide each year! The sewage is collected and then treated or disposed of. But what if, along the way, there were a way to make that sewage do something useful? It turns out that human urine is rich in nutrients, and some bacteria actually thrive on eating those nutrients. There are also devices called microbial fuel cells that can generate electrical… Read more

Time Required Very Long (1+ months)
Prerequisites Previous experience using a multimeter is helpful, but not required.
Material Availability The microbial fuel cell kit needs to be special ordered from the .
Cost Average ($50 - $100)
Safety Be sure to wear the gloves supplied with the kit when handling the microbial fuel cell's electrodes (its cathode and anode). The electrodes are made of a conductive material called graphite fiber and should not be placed near electronics or power plugs, or have their fibers dispersed in the air. The fibers will cause electrical shortages when they come in contact with electronics. Wear gloves when working with human urine. Adult supervision is recommended.
Science Fair Project Idea
If you want to get your friend's attention at a crowded sporting event with lots of people cheering, you need to shout. If you're trying to do the same thing in a quiet library, a whisper works. The detection limit for each of our senses depends on the amount of "background" stimulation that is already present. This project uses an LED control circuit to investigate detection of changes in light levels. Read more

Time Required Short (2-5 days)
Prerequisites Understanding of Ohm's Law and an understanding of logarithms. Note: the biggest expense is a powered, solderless breadboard, which can be used for future explorations in electronics.

Safety No issues
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

Safety Adult supervision is recommended.
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

Time Required Long (2-4 weeks)
Prerequisites A familiarity with basic chemistry is required. Experience with simple electronics would be helpful, but is not absolutely required. Although the procedure provides step-by-step instructions, this is a DIY (do-it-yourself) science fair project that may call for some creative problem solving on your part.
Material Availability Electronic components are required. See the Materials & Equipment list for details.

Safety Use caution when working with laser pointers. Wear safety goggles when using the drill.
Science Fair Project Idea
Do you read the list of ingredients in foods and drinks before you buy them at the grocery store? If you do, you may have noticed that many of the items that are blue in color have the same dye, called FD&C blue 1. In this chemistry science fair project, you will build a simple colorimeter, a device that measures the concentration of colored chemicals in solutions. You will use the colorimeter to measure the concentration of blue dye #1 in sports drinks, and to track the rate at which the… Read more

Do you ever wish you could hire someone to guard your favorite toys, or keep certain people from coming into your room? What if you could make a robot to do it for you? This project will show you how to build a simple security robot controlled by a motion-detecting sensor. When someone comes near your valuables or enters the room, the robot will spring to life and (hopefully) scare them away! Read more

Sometimes engineers get ideas to build robots from animals in nature. There are robot dogs, robot snakes, robot birds, robot cheetahs, and even tiny robotic insects! In this science project, you will build a robot insect of your own. The robot will automatically drive toward a light source, mimicking a behavior called phototaxis, seen in some insects. You will build your own robot and then make adjustments so it can reliably drive toward a light. Read more
