Science Fair Project Idea
thumbnail Isn't it nice to take a nice, hot shower or bath after a long day of playing outside? But have you really thought about how the hot water in your shower or bath gets hot? Sure, the water heater in your house gets it hot, but what makes the water heater work? Water heaters are powered by natural gas or electricity. But are there any other ways to heat water? What about using the Sun? In this science fair project, you'll give it a try by capturing energy from the Sun to heat water. Read more

Time Required Average (6-10 days)
Prerequisites You should have the patience and dexterity to coil several layers of wire neatly (or find someone who can help you). You will also need to hook up a basic circuit. Understanding electric circuits is not a prerequisite for this science project, though it will enable a deeper understanding of the electric generator.
Material Availability A kit containing all the specialty items needed for this project is available from the [# Link Name="Elec_p051.6" Value="HtmlAnchor" #].
Cost Low ($20 - $50)
Safety Neodymium magnets are very strong. Follow the safety guidelines in the Procedure for working with these magnets.
Science Fair Project Idea
thumbnail The electricity you use to power everyday devices is generated by electrical generators. These fascinating and powerful machines rely on magnets to function. Though they might seem extremely complicated, once you finish this science project, you will understand how, why, and when they generate electricity. You will build your own generator, make small changes in how exactly the magnets are placed, and test when moving magnets generate electricity. Read more

Science Fair Project Idea
thumbnail How can seawater from the oceans be turned into fresh water that is suitable for people to drink? Through a process called solar desalination! In this science project, you will make a solar desalination apparatus using readily available materials, and a power source that is free. How much water can the device produce, and is it still salty at all? What factors affect how effectively saltwater is turned into fresh water? Read more

Science Fair Project Idea
thumbnail Can you imagine designing and building a space telescope the size of a tennis court? Believe it or not, that is someone's job! Engineers are hard at work on the James Webb Space Telescope, or JWST. This telescope has the potential to enable astronomers to see light from when the Universe was first formed. No one knows what amazing discoveries this might lead to. However, to make the telescope work properly, engineers have to overcome a lot of challenges. In this science project, you can… Read more

Science Fair Project Idea
thumbnail Do you like getting something for nothing? Everybody likes getting things for free. How about getting energy and power for free? The Sun sends us free energy every second and all we have to do is collect it. Taking advantage of free energy can reduce our dependence on fossil fuels, which are harmful to our environment. In this science fair project, you will work with a solar panel, which is a collector of free energy, and investigate how varying the angle of the solar panel, and thus the amount… Read more

Science Fair Project Idea
Solar cells are devices that can be used as a source of power when there is light shining on them, but they stop producing energy when they are not in the light. One way to store the solar energy for later use is to use a solar cell to charge something called a capacitor. The capacitor stores the energy as an electric field, which can be tapped into at any time, in or out of light. In this electronics science project, you will use parts of a solar car to experiment with the energy storage… Read more

thumbnail Have you ever wondered what a wildlife biologist does? Ronnie and Denise from DragonflyTV found out firsthand when they worked with a local wildlife biologist to take a survey of the fish populations in their local lake. They wanted to determine what the biodiversity (number of different species in a habitat) was like so that they could find out how healthy the lake habitat was. In this science fair project you can take on the role of a wildlife biologist by examining the biodiversity of… Read more
