What do you think about killing vampires? No, no, not the kind that drink people's blood, but the
kind that suck your power and money away. Equipment like televisions, computers, printers, and fax machines
all use electricity to operate, of course, but do you realize that this equipment might still be sucking electricity from the wall, even when you think it's turned off? These electricity-suckers are called vampire loads. In this science project, you will investigate how much power these…

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.
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.
Sleeping in class isn't allowed... unless you're a computer! In fact, the Environmental Protection Agency (EPA) suggests that putting your school's computers to sleep when they're not in use might reduce a school's energy bill significantly. In a study done at the North Thurston public schools in Olympia, Washington, EPA officials worked with the district to cut computer energy and costs by approximately $45,000 annually! How? By implementing a variety of power-management strategies for the…

Every day, no matter where you are, you will see people using their cell phones. People use their cell phones for
more than just making calls though. They use them for texting and searching the Internet, too. But some health groups
are concerned that using your cell phone too much can be hazardous to your health as it exposes your body to electromagnetic radiation. In this electricity and electronics
science project, you will investigate how much radiation your cell phone emits when used…
One way to save water is to turn the faucet off while you brush your teeth. But did you know that there are products that can help save water even while the water is on? In this experiment find out how low-flow faucets and aerators work to reduce the flow of water. How much water can you save?

It's fun to host and attend parties. You can meet your friends, watch movies, and eat party food. Another thing that people like to do at parties is dance to music. Dancing is great exercise and just makes people happy. What if at the next party you attend, you could do your science fair project? Doesn't sound like a good idea? Well, in this electricity and electronics science fair project, you will make a dance pad that flashes lights when you step on it. Have your friends test it out for you.…
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?

If you've ever watched an adult pay for something by simply touching their credit card to a machine at a store, or you've done the same with a bus pass, you've seen an RFID tag in action. An RFID (Radio-Frequency IDentification) tag allows a card to be read by a computer from a short distance away. This is very convenient, but it also allows criminals to steal information about you. For instance, on the subway or the bus, someone standing next to you can use an RFID reader to access the data on…
Hooke's law says that the opposing force of a spring is directly proportional to the amount by which the spring is stretched. How accurately Hooke's law describe the behavior of real springs? Can springs be used to make accurate scales for weighing objects? Spring into action and find out for yourself with this project.
