Science Fair Project Idea
thumbnail Has your dog ever barked, seemingly for no reason at all? Or has your cat ever stopped and carefully smelled a spot that looked perfectly clean to you? Pets, like people, have senses that they use to learn about and to react to their world, but their senses can be stronger or weaker than people's. In this mammalian biology science fair project, you'll study your pet's sense of taste by conducting taste tests and watching how your pet acts to determine his or her favorite type, flavor, or brand… Read more

Science Fair Project Idea
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

thumbnail We are all familiar with the nursery rhyme, "Rain, rain, go away, come again some other day...", or the song "Singin' in the Rain." Numerous songs and stories describe our feelings about rain. Why so many? Because we humans understand how important rain is to our well-being. Rainfall, as part of the water cycle, brings water back to Earth that had previously evaporated or transpired from the surface. When water vapor in the atmosphere condenses into clouds and falls back to Earth as rain,… Read more

Science Fair Project Idea
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

Science Fair Project Idea
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

thumbnail French fries, hash browns, mashed potatoes with gravy, potato latkes, there are so many things to make with the humble potato. The potato is a tuber from the perennial plant Solanum Tuberosum of the Solanaceae family. There are actually about 5,000 varieties of potatoes, but most of them can be traced back to the original potato from southern Peru. This single ancestor originated more than 10,000 years ago. In addition to being high in vitamins and minerals, potatoes have a varying amount of… Read more

If you've ever been on a long hike, you probably already know how hungry all that walking can make you. But if you're going a long distance, the last thing you want is a heavy pack of snacks on your back. So what can you bring along for a healthy, hunger-satisfying, lightweight snack? How about dried foods, like banana chips or beef jerky? Many foods have high water content. The drying process removes much of the water from the food, leaving behind a lighter, but equally nutritious snack. Just… Read more
