Sixth Grade Energy & Power Science Projects (17 results)

Whether you are working, studying, or being entertained, much of our daily routines rely on being plugged-in. You probably don't spend a lot of time thinking about where all that power comes from, but someone has to! Figuring out the best ways to produce energy is a big job that is growing along with the world's population. Energy can also be a hot topic with argements about whether to invest in fossil fuels or clean renewable energies like solar, wind, water and geothermal. Take a first-hand look at some of the problems and challenges scientists and engineers are tackling as they look at making and storing energy in our collection of energy science and engineering projects.

Burning Biofuels: Comparing Nonrenewable and Renewable Fuels
Science Fair Project Idea
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

From Trash to Gas: Biomass Energy
Science Fair Project Idea
Have you ever dreamed of a world where you could take the scraps from last night's dinner and toss them into your car's fuel tank and make gas? Well, we're not quite in "Back to the Future" yet, but in this energy science fair project, you'll discover that food scraps, dead plants, sawdust, and other decaying organic matter, called biomass are a rich source of energy. You can get energy out of biomass by burning it, turning it into a liquid, or by turning it into a gas called biogas. You've… Read more

Go Green by Growing Green: How to Extract Energy from Grass
Science Fair Project Idea
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

Put Your Water to Work: Using Hydropower to Lift a Load
Science Fair Project Idea
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

Spare a Watt, Save a Lot
Science Fair Project Idea
Do you know how much power is used every day in your home? What you might not realize is that making simple changes can save you energy, power, and money. What would you do with extra money? Put it in the bank or get something that you really want? In this science fair project, you will investigate the different uses of electricity in your home and determine if there are simple changes that you can make to save energy and money. Read more
