Eleventh Grade, Energy & Power Science Projects (6 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 production is a complex topic with debates 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.

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…

Have you heard that garlic powder is supposed to inhibit the growth of bacteria? Which do you think would make a better disinfectant: a solution of garlic powder or a solution of bleach? This project shows you a straightforward way to compare the effectiveness of different disinfectants (or other antimicrobial agents), by measuring zones of inhibition on a culture plate.

"Gross! What is that in the toilet?" But maybe it's not just gross. Did you know there are bacteria that digest organic waste and create electrons? What if there was a way to collect those electrons to power a circuit? In this science fair project, you will make a microbial fuel cell to collect the electrons that the bacteria—anaerobic bacteria—create...only, you'll be using mud, which is much safer to handle than wastewater. If you would like to learn how to reuse and recycle an…

Remembering to take medicine at the right time can be hard, especially if you need to take multiple medications at different times of day. It might not be a big deal if you forget to take your daily multivitamin, but for some people, forgetting to take medication at the right time can be dangerous. What if you had a device that could not only set off an alarm at the right time, but also automatically dispense the right pills for you? In this project, you will build an automatic medicine…

Most of the energy and fuel that we use in the United States is derived from burning fossil fuels. Fossil fuels are the remains of plants and animals that lived hundreds of millions of years ago. Examples of fossil fuels include coal, petroleum oil, and natural gas. Burning coal releases 21.3 gigatons of carbon dioxide— a greenhouse gas that may be responsible for global warming and climate change—into the air in one year. About half of this amount is absorbed by natural processes…

Global warming, climate change, melting ice caps—these are all big events that have an impact our environment. What can we do to help reduce the impact? We can reduce, reuse, and recycle. What can cities do to help? Cities can eliminate waste by saving energy. Cities around the world are switching from incandescent traffic signals to LED traffic signals to save energy and money. That's because LEDs are more efficient than incandescent lamps, which means that LEDs produce more light…

This project is a great way to "bring home" the concept of energy use. All you need to get started is a good-sized sample of monthly electric bills from households in your area. Building from this simple beginning, you can ask questions that can take you in many different directions. For example: How much electricity does the "average" person in your area use per month? How much does electricity use vary among different families?

Artificial intelligence (AI) programs can now generate photorealistic pictures of people who do not exist in the real world. How can you tell if a picture is of a real person or a fake, AI-generated person? What features of the picture do people use to decide whether the face is real or AI-generated? In this project, you will explore these questions as you ask volunteers to look at both real and AI-generated pictures of human faces.

If you are interested in exploring how renewable energy can improve the environment, this project could be for you. You'll take on a real-life engineering challenge: deciding whether the benefits of a renewable energy technology are worth the cost to implement it. Some sample questions are suggested, but you can also come up with your own question that matches your specific renewable energy interest. Is there such thing as a free lunch?
