Science Fair Project Idea

Scientific Method

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

The Power of Heat Is Right Under Your Feet with Geothermal Energy

Science Fair Project Idea

Scientific Method

You might know that we are able to get renewable energy from the Sun, the wind, and water, but did you know we can get renewable energy from Earth itself? The temperature inside of Earth can reach 9,000°F—that kind of heat can be used to make a lot of energy here on the surface! This source of energy is called geothermal energy and it is all about taking advantage of the heat within Earth. So try this science fair project out and find out how to use the heat that lies beneath your… Read more

How Does Solar Cell Output Vary with Incident Light Intensity?

Science Fair Project Idea

Scientific Method

Solar cells are an alternative method for generating electricity directly from sunlight. With this project, you can get down to the atomic level and learn about the world of solid-state electronics as you investigate how solar cells work. Your experiment will measure the effect of changing light intensity on power output from the solar cell. A possible variation would be to investigate the effect of changing the color of the light.

A Cool Way to Make Electricity: Solar Cell Power Output vs. Temperature

Science Fair Project Idea

Scientific Method

Solar cells provide a clean way of making electricity directly from sunlight. In this project you will build a simple circuit and experimental setup to investigate whether the power output of a solar cell changes with ambient temperature. Read more

Wily Waves: Build an Oscillating Water Column to Extract Energy from Ocean Waves

Science Fair Project Idea

Scientific Method

The ocean is a wondrous force of nature. It affects the weather, and provides us with food and renewable energy to power our lives. How can the ocean provide us with renewable energy? One way is to extract the energy that is in the waves. There are many kinds of power systems that can be installed to extract energy from the waves, depending on the location. In this energy and power science project, you will build and test a simple model of an oscillating water column device to create power. How… Read more

Tireless Tides: Extracting Energy from Ocean Tides

Science Fair Project Idea

Scientific Method

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

Catch the Wave!

Science Fair Project Idea

Scientific Method

There is a lot of energy that can be harvested from moving water. Energy can be extracted from water rushing over a waterfall and from the regular patterns of the ocean's tides. The energy that propels waves forward in the oceans can also be extracted and used. But can wave energy power plants be built anywhere there is water? In this energy science fair project, you will use ocean buoy data and mathematics to determine which locations along the coasts of the United States can sustain a wave… Read more

Burning Biofuels: Comparing Nonrenewable and Renewable Fuels

Science Fair Project Idea

Scientific Method

Have you considered where the gasoline that your parents put in your car comes from and how long that source will last? The fuel that most vehicles use, gasoline, is a petroleum product. Petroleum is a fossil fuel and is a nonrenewable form of energy, meaning we use it faster than it is able to be reproduced. Burning fossil fuels also produces pollutants that might hurt our environment. Using a kind of fuel from a renewable source would help save Earth's natural resources and cut down on… Read more

Renewable Energy Resources

Science Fair Project Idea

Scientific Method

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
