Cold Room? Heat It Up with A Homemade Solar Air Heater
Science Fair Project Idea
Scientific Method
What do humans need to survive? We need food, water, and warm shelter. We all need a warm place to live, particularly when it's chilly outside. How do many of us warm our houses or apartments? We depend on fossil fuels to supply gas and electricity to our heaters. But burning fossil fuels to create energy is harmful to the environment. What if there was a way to warm our homes without burning fossil fuels and it was free? In this science fair project, you will build a solar air heater and see… Read more
Design a Mini Solar Tracker System
Science Fair Project Idea
Engineering Design Process
How can you squeeze as much power as possible out of solar panels if you do not have a lot of space to install them? By tracking the sun! Keeping a solar panel pointed directly at the sun throughout the day can maximize the amount of power it produces. In this project you will design, build, and test your own miniature solar tracking system using a fun block-based programming language - no coding experience required! Read more
Energy Is Blowing in the Wind
Science Fair Project Idea
Scientific Method
Have you ever watched how trees sway and bend in a strong wind? Have you ever thought about all the homes that could be powered with forces from the wind? In this project you'll discover, through trees, good places in your community for generating wind power. Read more
Extracting Heat Energy from a Compost Pile
Science Fair Project Idea
Scientific Method
Earth, the Sun, wind, and water are all sources of renewable and sustainable energy—and sources you probably already know about. But did you know that you can get energy from such things as banana peels, coffee grounds, and newspaper? In a process called composting, you can transform kitchen and other solid wastes into a product that is beneficial for your garden: homemade fertilizer. As the waste decomposes, it also creates heat. Can this naturally created heat be put to use? In this… Read more
Find the Best Place to Put a Solar Panel
Science Fair Project Idea
Scientific Method
Imagine trying to put a solar panel on your roof or outside your home to generate clean, renewable energy. Where would you put it so it generates as much power as possible throughout the day? What direction should it face? Is there a way to take measurements to find the best location before you install the panel? In this project, you will use a tiny programmable device called a micro:bit to record light data and find the best place to put your panel. Read more
Free Power from the Sun!
Science Fair Project Idea
Scientific Method
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
From Trash to Gas: Biomass Energy
Science Fair Project Idea
Scientific Method
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
Fuel Cells—Fueling the Future!
Science Fair Project Idea
Scientific Method
You probably know that turning off the lights and the water, and not wasting paper are all ways to help the environment and conserve our resources. Did you know that another way is to use fuel cells? A fuel cell is a device that converts the energy in chemicals to electricity and it creates no pollution. The starting chemical does not have to be something complex — in fact you it can even be water! In this science fair project try your own hand at converting water to electricity with the… Read more
Geology and Energy Resources
Science Fair Project Idea
Scientific Method
How is geology important for our energy resources? Coal, oil, and natural gas are formed by geological processes over millions of years. Certain geological formations can indicate a reservoir of coal, oil, or natural gas. Also, geothermal processes can be used as an energy resource. How are these formations identified? How are the resources extracted? You can use the National Geospatial Program to access, view, and download information from geospatial databases containing a broad spectrum… Read more
High-Speed Magnets: Exploring Faraday's Law and Lenz's Law
Science Fair Project Idea
Scientific Method
Safety Notes about Neodymium Magnets: Neodymium magnets are very strong. Adult supervision is recommended when using them. Be careful not to drop the magnets, and do not let them slam together or fall. They may pinch your fingers, crack, or shatter. Keep magnets away from small children, pets, credit cards, and pacemakers. In the Science Buddies project Human-Powered Energy, you can learn about the basics of magnetic induction, or how moving magnets can be used to generate an… Read more
