Science Fair Project Idea
Antibiotics work by destabilizing the metabolism or cellular structure of bacteria, preventing growth, and causing bacteria to die. Some strains of bacteria have mutated and found a way to resist the actions of antibiotics. These are called resistant strains because they resist the actions of available antibiotic treatments. There are many different types of antibiotics that are continually being developed to combat new strains of resistant bacteria. Some antibiotics work better on different… Read more

Disinfectants are products that kill harmful bacteria that inhabit surfaces. Disinfectants can be in household and personal cleaning products. Which products work best? Compare different household cleaning products, like bleach or Lysol, to see which ones kill the most bacteria. Compare different brands of antibacterial hand soap or dish soap to see which brand is the most effective. How do hand sanitizers work? Compare rub-on hand sanitizers to see if they work better than alcohol, or compare… Read more

thumbnail Topsoil is packed with bacteria that generate electricity when placed in a microbial fuel cell (MFC). Because such bacteria-laden soil is found almost everywhere on Earth, microbial fuel cells can make clean, renewable electricity nearly anyplace around the globe. As natural resources are being depleted, scientists' attention has shifted to pursuing alternative energy sources, such as MFCs, even more than before. A microbial fuel cell, also known as a biological fuel cell, is a device that can… Read more

Time Required Very Long (1+ months)
Prerequisites Previous experience using a voltmeter/multimeter is helpful, but not required. A basic knowledge of how to work with bacteria is also needed 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 A microbial fuel cell and other specialty items are needed. See the Materials tab for more details.
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 [# ProjectGuide Name="Advanced.MicroorganismsSafetyGuide" Value="HtmlAnchor" HtmlShortTitle="true" #] before starting any experiments. [# ProjectGuide Name="Advanced.ScientificReviewCommitteeSRC" Value="HtmlAnchor" HtmlText="SRC approval" #] may be necessary. Adult supervision is recommended.

Our metabolism changes as we get older, a sad fact of life that we cannot change. Old age affects our bodies in many ways. Changes in musculature, bone strength, energy, diet and breathing are some of the many ways we change as we age. You might notice that people often get out of breath when they are older and doing a physical activity. Why do some people feel out of breath, while others do not? Does this change correlate with age? Could this reflect a difference in lung capacity between… Read more

Most of the energy and fuel that we use in the United States is derived from burning fossil fuels. Fossil fuels are the remains of plants and animals that lived hundreds of millions of years ago. Examples of fossil fuels include coal, petroleum oil, and natural gas. Burning coal releases 21.3 gigatons of carbon dioxide— a greenhouse gas that may be responsible for global warming and climate change—into the air in one year. About half of this amount is absorbed by natural processes… Read more

Does listening to classical music help or hinder concentration and performance on cognitive tasks? You'll need help from a teacher to design two short, age-appropriate worksheet tests for this experiment. The tests should be of equal difficulty. You'll also need the cooperation of several additional classroom teachers in order to test enough students (at least 50-100, see the Science Buddies resource: ). Half the students will take test A while listening to classical music and test B with no… Read more

[[ Image [] [] Image ]] The Falkirk Wheel is a rotating boat lift connecting the Forth and Clyde Canal with the Union Canal near Falkirk in central Scotland. It consists of two diametrically opposed caissons which rotate to lift boats between the two canals through a height of 35 meters. The wheel is always perfectly balanced and, despite its enormous mass, rotates through 180° in less than four minutes, using just 1.5 kilowatt-hours (Wikipedia contributors, 2006).

What do pneumonia, ear infections and strep throat have in common? When they are caused by bacteria (instead of viruses) they are treated by antibiotics. That sounds simple enough, right? You have probably had antibiotics several times in your life. You go to the doctor because you feel lousy, if he or she determines you have a bacterial infection you get a prescription for antibiotics, and within the first day or so you often start feeling much better. Unfortunately, there is a large… Read more

Coal, gas, and oil are energy resources that are not renewable, meaning that once we use up the world's supply of these natural resources there will not be any left. There is a lot of debate about how long these resources will last. One way to ensure that we will not find ourselves in an energy crisis is to develop energy resources that are renewable. Renewable energy is a resource that cannot be used up. Investigate the many uses of renewable energy: solar energy, wind energy,… Read more

Beats are a pattern of oscillating sound intensity (i.e., the volume of the pattern grows and fades with a regular cycle). They occur when two tones of almost equal frequency interfere. People can perceive beat frequencies below about 7 Hz. Figure out how to create sound files to play pure tones on your computer. Create files with a pure tone of one frequency in the left channel, and a pure tone of a different frequency in the right channel. Systematically explore different frequency… Read more
