Science Fair Project Idea
Do you hate shots? Do you complain about paper cuts? Imagine if you had to give yourself shots a couple of times a day, as well as prick your finger, on purpose, even more frequently. Of course, if you have diabetes you do not have to imagine this; it is your reality. People who have diabetes usually need to keep close track of how much sugar is in their blood (called their blood glucose levels) by testing a drop of blood from a finger prick. If there is too much sugar in their blood, some… Read more

Time Required Average (6-10 days)
Prerequisites Some familiarity with electronic circuits and using breadboards would be helpful, though it is not required for this project. Completion of a basic chemistry class is also recommended before trying this project.
Material Availability A pump and other electronics parts must be specially ordered to do this project. See the Materials list for details. Estimated project time includes shipping of specialty components.
Cost Average ($40 - $80)
Safety Some parts of the circuit can get warm during normal operation. Do not leave the circuit operating when unattended. Be very careful with your wiring to prevent short circuits from happening; short circuits can get very hot and cause plastic parts of the circuit to melt.
Science Fair Project Idea
Generating power from mud sounds like science fiction, but it is actually real science, and a promising source of alternative energy. Topsoil is packed with bacteria that generate electricity when placed in a microbial fuel cell. Because such bacteria-laden soil is found almost everywhere on Earth, microbial fuel cells can make clean, renewable electricity nearly anyplace around the globe. They are an up-and-coming technology that scientists and engineers are working to make even more… Read more

Time Required Very Long (1+ months)
Prerequisites We recommended that you have a basic knowledge in physics of electricity and familiarity with the concepts of conductivity, electric current, resistance and electrical power. Having used a multimeter before 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, power plugs, or have their fibers dispersed in the air. The fibers will cause electrical shortages when in contact with electronics.
Science Fair Project Idea
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

Don't you hate it if you want to pour yourself a cup of milk and all you get is milk clumps? What happened to the milk is called coagulation, which is the mechanism that occurs when proteins in the milk clump together. Without coagulation, or curdling, there wouldn't be any cheese or yogurt which is why it is a very important process in the food industry. But what makes milk curdle? In this science project you will use pineapple juice to curdle milk and measure the coagulation process over time… Read more

A simple circuit and a servo motor are all you need to turn any work of art into an interactive moving creation that is happy to see you. Light sensors see your shadow as you walk past your artwork and make a servo motor move back and forth. Waving arms? Turning heads? It is all up to you! Read more

What can you do with a bucket of soil? You could use it to grow some beautiful plants and vegetables—or you could use it to produce electricity! Surprised about that? You actually can power electric devices with just mud! Are you curious about how this works? You need some little helpers in the soil—bacteria—that are able to turn their food sources within the soil into electricity in a device called a microbial fuel cell. But is this possible with any soil and does the soil… Read more

Strike a key on the piano, and you hear the string vibrating. Just about any object vibrates when it's knocked, but how much and how fast? What properties of the material affect the way it vibrates? This project helps you find out. You'll build a simple light-sensing circuit for measuring the frequency of vibrating springs. Read more

Solar cells are an alternative method for generating electricity directly from sunlight. With this project, you can get down to the atomic level and learn about the world of solid-state electronics as you investigate how solar cells work. Your experiment will measure the effect of changing light intensity on power output from the solar cell. A possible variation would be to investigate the effect of changing the color of the light.

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
