Science Fair Project Idea
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

Time Required Very Long (1+ months)
Prerequisites Previous experience using a multimeter and being familiar with the physics of electricity is helpful, but not required.
Material Availability The microbial fuel cell kit needs to be special-ordered from the .
Cost Average ($50 - $100)

What is the first thing you do when you wake up on a cold, frosty morning? Snuggle down deeper under the covers? Animals, like puppies and piglets, do not like being cold either, but they do not have hands or blankets to wrap themselves up. So when animals get chilled, they change their behavior and do things like huddle—they curl up close to other animals. In this mammalian biology science fair project, you will see just how much huddling can help reduce heat loss. Read more

How do you feel when you ride your bike into a strong wind? Do your legs feel like lead? How about when the wind is at your back? Does that make you feel ready for the Tour de France? In this science fair project, you will investigate how wind-powered devices, like pinwheels, also react in different ways to the direction of the wind. Read more

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

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.

Have you ever made your own ice cream? If you have, you probably know that you need to get the ice cream mixture really cold to freeze it quickly. Ice cubes alone will not do the job, but if you add chemicals, such as salt or sugar, to the ice cubes that surround the ice cream container, the mixture gets cold enough to freeze. Why does that work? How does adding salt or sugar affect the freezing point of water? Find out with this ice-cold science project and use your results to make your own… Read more

Safety Be careful when handling the glass test tubes. Exposing them to very cold temperatures or rapid temperature changes makes them more vulnerable to breakage, especially when they get bumped or handled roughly.
Science Fair Project Idea
Bacteria are powerful little creatures. They can dispose of contaminants, make us sick and did you know they can even generate electricity? In devices, called microbial fuel cells (MFC) they can extract electrons from their food sources such as organic materials and feed them into an electrical circuit to generate power. This way they can even turn plain soil into a source of energy! Does it matter though what kind of food the bacteria "eat"? Find out how bacteria grow in a microbial fuel cell… Read more

If you had to choose between having your favorite dessert, going to a movie, or spending the night at a friend's house, which would you choose? This science project shows you how you can "ask" a sowbug (or pillbug) a similar question in order to learn about their preferences. Give it a try to find out what types of microenvironments these tiny crustaceans prefer. Read more

Science Fair Project Idea
If you have ever tried to hit a target (such as a trash can) with a wad of paper, you know that aim is everything. But it is not always easy to get it right every time! Missing is not that big a deal with a wad of paper, but what if you were in an invading army in the Middle Ages, using a catapult to hurl huge stones and knock down castle walls? For a successful invasion, it would be important to know exactly how far, and how reliably, a catapult could launch a projectile. In this project you… Read more

You are right next to the basket and someone passes you the ball. Will you go for a direct shot or will you use the backboard and take a bank shot at the basket? Would different positions on the court give you a higher chance of making a shot using the backboard than others, even when keeping the distance from the hoop the same? In this science project, you will build a scale model and test different positions on the court to determine if one results in a better chance of making a bank shot… Read more
