Science Fair Project Idea
thumbnail The enormous task of cleaning up oil spills in oceans and seas has burdened industry, government, and environmentalists for decades. The cleanup is almost always difficult. It involves great amounts of time, resources, and money to remove the oil from the water, and the cleanup is often only partially successful. Today, however, scientists are coming to the rescue, developing a new technique that combines nanotechnology and magnetism. In this science project, you will test the proposed… Read more

- Less Details
Time Required Average (6-10 days)
Prerequisites None
Material Availability Specialty items (ferrofluid and neodymium magnet) are needed for this project. See the Materials and Equipment list for details.
Cost Low ($20 - $50)
Safety Neodymium magnets are very strong. Some have the capacity to interfere or reset pacemakers. Never put a neodymium magnet in your mouth. Always keep them away from computers, credit cards, and other magnetized objects.

Ferrofluids create stains on skin and other materials, so take appropriate measures to keep the fluid contained to the working area.

thumbnail Have you ever seen clothing with built-in lights? This might sound like something out of a science-fiction movie, but electronic textiles (or e-textiles for short) really exist. Instead of using hard surfaces for circuits (like what goes inside your computer or cell phone), e-textiles weave electrical parts like batteries, wires, and lights directly into clothing that you can wear to make the clothing do fun, interesting things like light up, respond to sound, or even serve medical purposes… Read more

Science Fair Project Idea
thumbnail From traffic safety lights to neon signs, lights have a way of getting peoples’ attention. So it makes sense that if a person wants to get attention, wearing clothing with built-in lights might help. These types of clothing, called electronic textiles (or e-textiles for short) already exist. Instead of using hard surfaces for circuits (like inside your computer or cell phone), e-textiles weave electrical parts like batteries, wires, and lights directly into wearable clothing so it can do… Read more
Elec_p076

- Less Details
Time Required Average (6-10 days)
Prerequisites Familiarity with basic electronics concepts like positive and negative terminals as well as open and closed circuits will be helpful for this science project. Students with no experience building circuits may want to try the simpler but thematically simlar project: [# ProjectIdea Name="Elec_p077" Value="HtmlAnchor" #].
Material Availability This science project requires special LEDs designed for use with e-textiles, and it will be much easier to do with a soldering iron. See the Materials and Equipment list for details.
Cost Average ($40 - $80)
Safety Soldering irons can get extremely hot and burn your skin if you touch them accidentally. They can also cause fires if left unattended. Adult supervision is required when using a soldering iron, especially if you are not familiar with using one. Science Buddies recommends using lead-free solder, especially in homes with pets and small children.
Science Fair Project Idea
thumbnail Earth is an amazing planet. It has everything that we need: food, shelter, and water. Sure, we need water to drink, but have you thought about using water to create energy? Moving water has a lot of energy and all we need to do is to harness it. Moving water made the Grand Canyon. That took a lot of energy! In this science fair project, you will demonstrate the power of water by converting the kinetic energy in moving water to mechanical energy, which will lift a small weight. Read more

Science Fair Project Idea
thumbnail Many things in nature are periodic: the seasons of the year, the phases of the moon, the vibration of a violin string, and the beating of the human heart. In each of these cases, the events occur in repeated cycles, or periods. In this project you will investigate the periodic motion of a spring, using a mini Slinky®. Basic physics will then allow you to determine the Hooke's Law spring constant. Your analysis will also yield the effective mass of the spring, a factor that is important in… Read more

Science Fair Project Idea
thumbnail Mowing the lawn is hard work, especially on a warm day. Not only do you have to mow the grass, but you also have to dispose of the clippings. Some people add the clippings to a compost pile in their yard, which is a great idea. But did you know that some grasses can be used as a source of energy? In this energy science fair project, you will learn more about a type of energy called biomass energy. You will grow different kinds of grasses and see which type of grass gives you the most biomass,… Read more

Science Fair Project Idea
thumbnail Living in the industrialized world, like the United States, we are fortunate because we don't have to worry about the quality of our drinking water. Your community has the means to clean and provide water to you. But in many parts of the world, people don't have this luxury. Whether it is due to war or poverty, the lack of clean water leads to many health and social problems. In this environmental engineering science project, you will learn about different methods to filter out impurities in… 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

thumbnail Making your own bubble solution is fun, but sometimes the bubbles don't seem to work as well as the solutions you buy in the store. In this experiment you can test if adding corn syrup or glycerin to your bubble solution will make it just as good as the stuff you can buy. This experiment will have you blowing bubbles! Read more

Time Required Long (2-4 weeks)
Prerequisites You will need to be flexible and creative in carrying out the procedure. You should be prepared to adjust the procedure, as needed, to ensure that the results are due to the detergents being tested and not variations in the worms' conditions.
