Have you ever wondered how your cell phone or laptop keeps running once you unplug it? Sure, it is the battery that makes your portable electronics work, but how exactly does a battery do that, and from where does the electricity come? Generally, in a battery chemical energy is converted into electrical energy. In fact, many different types of batteries exist that are all based on a different set of chemical reactions. In this science project, you will explore a special battery variant called… Read more

You probably know that turning off the lights and the water, and not wasting paper are all ways to help the environment and conserve our resources. Did you know that another way is to use fuel cells? A fuel cell is a device that converts the energy in chemicals to electricity and it creates no pollution. The starting chemical does not have to be something complex — in fact you it can even be water! In this science fair project try your own hand at converting water to electricity with the… 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

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.

Imagine telling your friends about your latest science project: using a battery to make a light turn on. You might get some blank stares...sounds a little boring and basic, right? Now tell them you will do it with a potato! Yes, you can actually use fruits and vegetables as part of an electric power source! Batteries power many things around you, including cell phones, wireless video game controllers, and smoke detectors. In this science project, you will learn about the basics of battery… Read more

Your drinking water probably started out brown and muddy. Are you surprised? Maybe you were picturing it flowing from a clean mountain spring instead? All over the world, including in 68% of American homes, people get their drinking water from rivers, lakes, and other surface waters. This water is filled with dirt, debris, and other contaminants as it travels hundreds of miles. So, how does your drinking water go from brown and muddy to crystal clear? Often, flocculants—substances that… Read more

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 make a very simple electronic device to measure the light given off by luminescent materials. The device will be used to study how temperature affects luminescence. Read more

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

The makers of sports drinks spend tens to hundreds of millions of dollars advertising their products each year. Among the benefits often featured in these ads are the beverages' high level of electrolytes, which your body loses as you sweat. In this science project, you will compare the amount of electrolytes in a sports drink with those in orange juice to find out which has more electrolytes to replenish the ones you lose as you work out or play sports. When you are finished, you might even… Read more

Have you ever wondered how nutritionists know how many Calories a certain food contains? In this project you will learn a method for measuring how many Calories (how much chemical energy) is available in different types of food. You will build your own calorimeter to capture the energy released by burning a small food item, like a nut or a piece of popcorn. This project gives a new meaning to the phrase "burning calories!"
