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

Think Like a Computer: Try Machine Learning

Science Fair Project Idea

Engineering Design Process

What should you eat for breakfast today? What should you wear to school? You make many decisions every day and consider lots of information when making those decisions. What if you could train a computer to make those decisions for you using artificial intelligence? In this project, you will not need to do any computer programming yourself, but you will do some simple math to show how a computer program called a neural network can learn to make decisions. If you want to try a version of the… Read more

No Pain, Lots of Game

Science Fair Project Idea

Scientific Method

You might have heard the expression, "Take two aspirin, and call me in the morning." What if instead a doctor said, "Play two video games and call me in the morning"? Would you be shocked? Or think it was time for a new doctor? In this science fair project, you'll investigate whether video games, and other forms of mental distraction, have the power to relieve pain. Read more

Abracadabra! Levitating with Eddy Currents!

Science Fair Project Idea

Scientific Method

Did you know that not all trains run on tracks? Some of the world's fastest trains are magnetic levitation trains (maglev). This means that the carriage of the train is suspended over the rails with no support, but only with magnetic fields! There is a physical explanation for magnetic levitation, and if you would like to learn more about magnetism and current, this is a science fair project that you must try! Read more

The Sweet Beginnings of Caramelization

Science Fair Project Idea

Scientific Method

Caramelization is the name of the cooking process that occurs as sugar is heated and the molecules begin to break apart. But what happens to the sugar as it breaks apart? And what do the physical changes mean for the flavor of the sugar? Using the Internet or cookbooks, read up on the chemistry of caramelization, then head to the kitchen with an adult to caramelize your own batch of sugar. With an adult's help, dissolve 1 1/3 cups of sugar in 2/3 cup of water. Heat the mixture in a pan over… Read more

Want to Warm Up or Cool Down? Go Underground!

Science Fair Project Idea

Scientific Method

Have you ever been so cold sitting in your house in the winter that you feel like icicles could grow off your nose, and your feet could turn into blocks of ice? Or have you ever been so hot in your house in the summer that sweat just drips off you? Making yourself comfortable can mean turning on the heater or the air conditioner, but that costs money. Being cozy or cool does not have to cost a lot of money if you use a geothermal heat pump. In this project, you will build a model geothermal… Read more

Minding your Mummies: The Science of Mummification

Science Fair Project Idea

Scientific Method

Have you ever seen or heard of the movies The Mummy or The Mummy Returns? Mummies have always played a part in nightmares for Western cultures, but in ancient Egypt, mummification was a serious religious ritual. They believed that preserving human remains was necessary so that the previous owner could enjoy the fruits of the afterlife. In this science fair project, you will learn about the rituals and science of mummification by mummifying a hot dog. Read more

Water-Wise: Building a Rainwater Collection System

Science Fair Project Idea

Scientific Method

We are all familiar with the nursery rhyme, "Rain, rain, go away, come again some other day...", or the song "Singin' in the Rain." Numerous songs and stories describe our feelings about rain. Why so many? Because we humans understand how important rain is to our well-being. Rainfall, as part of the water cycle, brings water back to Earth that had previously evaporated or transpired from the surface. When water vapor in the atmosphere condenses into clouds and falls back to Earth as rain,… Read more

Make a Glitter Surprise Package

Science Fair Project Idea

Engineering Design Process

Have you ever seen a video of a glitter prank package? They usually show an unsuspecting person opening a package or a gift, only to be sprayed by a shower of glitter. Former NASA engineer Mark Rober got tired of thieves stealing packages off his porch, so he decided to build an elaborate decoy glitter package*, as he shows in this video. Mark's device involves a lot of custom software, electronics, and 3D printing, so might seem a little intimidating if you are new to engineering. The summary… Read more

Singing Wine Glasses

Science Fair Project Idea

Scientific Method

The American holiday of Thanksgiving is a favorite of many. Friends and family getting together, a big feast, fancy china and glassware on the table. Who can resist the temptation to make the wine glasses sing? Find out more about how this works with this project! Read more
