Does your skin get dry? Or do you know someone with dry skin? Dry skin can be a real medical problem for some people. You may have seen many kinds of lotions, creams, and ointments advertised as restorative for dry skin, especially dry hands. But how well do they work? And which ingredients are most important in making them work? In this science project, you will create a model of human skin using JELL-O® and test how well skin moisturizing products with different ingredients keep the… Read more

Do you know that many consumer products, such as sports clothes, cosmetics, and even food containers contain tiny silver particles? These so-called nanoparticles—usually 1–100 nanometers (a billionth of a meter) in size—are toxic to bacteria and fungi and therefore, are used to prevent them from growing on everyday items you use. But what happens if the silver nanoparticles get into the water; for example, when you wash off your makeup or clean your clothes? Do they… Read more

Have you ever experienced heartburn after eating a large, greasy meal? Or have you heard of someone complaining about heartburn pains? It's very common; over 60 million people in the U.S. have heartburn at least once every month. Heartburn pain usually results from stomach acids escaping from the stomach and irritating the esophagus above it. Luckily, there are medical drugs, called antacids, which can help relieve heartburn pain. But how do antacids work, and how effective are they? In this… 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

Time Required Very Long (1+ months)
Prerequisites Previous experience using a multimeter and familiarity with the physics of electricity is helpful, but not required. A basic knowledge of how to work with bacteria is also recommended to complete this science fair project. Consult the [# ProjectGuide Name="Advanced.MicrobiologyTechniquesampTroubleshooting" Value="HtmlAnchor" HtmlText="Microbiology Techniques and Troubleshooting" #] guide for information on how to conduct microbiology experiments.
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. Use sterile technique when growing the bacteria. Read the before starting any experiments. may be necessary. Adult supervision is recommended.
