Others Like “Put Your Water to Work: Using Hydropower to Lift a Load”

Science Fair Project Idea
thumbnail Renewable energy is the energy that is extracted from natural sources, such the Sun (solar), earth (geothermal), wind, and water (hydropower). These sources are renewable because they can be replenished by the same natural sources within a short period of time. Hydropower energy is extracted from moving water, like ocean wave energy and tidal energy. In this energy science fair project, you will make a model of a tidal barrage (also known as a dam) and investigate how emptying the tidal barrage… Read more

thumbnail It's hard to believe that the same water that you use every day to quench your thirst, cook with, bathe in, swim in, and wash your clothes and dishes, is capable of another trick—it can make electricity! Electricity can be generated through the flow or through the fall of water. A big, fast-flowing river, for instance, contains a lot of moving energy that provides enough pressure to turn the blades of a turbine and run an electric generator. This same pressure can also be created though… Read more

thumbnail 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
thumbnail People often call cardiovascular disease a "silent killer." This disease sneaks up and causes damage, but patients don't realize it—until serious symptoms start. That is why physicians recommend keeping your cardiovascular system healthy. A healthy cardiovascular system gives us the energy and the stamina to do all of the things that we want to accomplish, such as do our best in school and perform well in sports. But what makes a cardiovascular system unhealthy, and what are the… Read more

Science Fair Project Idea
thumbnail "Gross! What is that in the toilet?" But maybe it's not just gross. Did you know there are bacteria that digest organic waste and create electrons? What if there was a way to collect those electrons to power a circuit? In this science fair project, you will make a microbial fuel cell to collect the electrons that the bacteria—anaerobic bacteria—create...only, you'll be using mud, which is much safer to handle than wastewater. If you would like to learn how to reuse and recycle an… Read more

Time Required Very Long (1+ months)
Prerequisites You will need to be familiar with the procedures for handling biologically hazardous material. Read the [# ProjectGuide Name="Advanced.MicroorganismsSafetyGuide" Value="HtmlAnchor" HtmlShortTitle="true" #] from the Science Buddies Project Guide to learn more about handling biologically hazardous materials. You also need to have access to a lower-order stream of water or a creek. See the Introduction for an explanation of this type of stream. Try to avoid streams in which the bed is rocky. The benthic mud sample should be from an area that has a thick, rich mud bed.
Material Availability Specialty items required
Cost High ($100 - $150)
Safety Adult supervision is recommended. Be careful when using a hot stove and a drill. Remember to always wear safety goggles when drilling. Exercise caution when working near a stream or creek. Water currents can be stronger than they look.
Science Fair Project Idea
thumbnail Water is an interesting thing. We drink it, swim in it, and wash ourselves with it. We can get energy from water by damming it and sending it through a turbine. But did you know that we can use the natural electrical charges present in water and a Kelvin electrostatic generator to create sparks? You can even use a Kelvin electrostatic generator to temporarily light a bulb! Now that is one bright idea! Read more
