Science Fair Project Idea
thumbnail What is the first thing you do when you wake up on a cold, frosty morning? Snuggle down deeper under the covers? Animals, like puppies and piglets, do not like being cold either, but they do not have hands or blankets to wrap themselves up. So when animals get chilled, they change their behavior and do things like huddle—they curl up close to other animals. In this mammalian biology science fair project, you will see just how much huddling can help reduce heat loss. Read more

Science Fair Project Idea
thumbnail You might know that we are able to get free energy from the Sun, the wind, and water, but did you know we can get free energy from Earth itself? The temperature inside of Earth can reach 9,000°F—that kind of heat can be used to make a lot of energy here on the surface! This source of energy is called geothermal energy and it is all about taking advantage of the heat within Earth. So try this science fair project out and find out how to use the heat that lies beneath your feet! Read more

Science Fair Project Idea
thumbnail Have you ever been so cold sitting in your house in the winter that you feel 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. Still, being cozy or cool doesn't have to cost a lot of money if you use a geothermal heat pump. In this project you will build a model… Read more

Science Fair Project Idea
thumbnail The ingredients in Alka-Seltzer® tablets undergo a chemical reaction that produces carbon dioxide gas as soon as the tablets hit water. Do you think you can cause the tablets to produce gas faster by breaking them into smaller pieces before dropping them in water? Find out for yourself with this project. Read more

Science Fair Project Idea
thumbnail This is a straightforward, fun project to measure the rate of the chemical reaction that occurs when Alka-Seltzer® tablets are plopped into water. You'll track the volume of carbon dioxide gas produced at regular intervals after the reaction begins. How does changing the temperature of the water affect the production of gas? Read more

Science Fair Project Idea
thumbnail Can you imagine designing and building a space telescope the size of a tennis court? Believe it or not, that is someone's job! Engineers are hard at work on the James Webb Space Telescope, or JWST. This telescope has the potential to enable astronomers to see light from when the Universe was first formed. No one knows what amazing discoveries this might lead to. However, to make the telescope work properly, engineers have to overcome a lot of challenges. In this science project, you can… Read more

Science Fair Project Idea
thumbnail There is nothing quite like the smell of fresh-baked bread to make your mouth water! As any baker can tell you, you cannot bake bread without yeast. Yeast actually eat sugar so that they can reproduce and make more yeast, and make bread dough rise. But can they use sugar substitutes to do this? In this science project you will get to investigate how well yeast grow with sugar substitutes as a food source. Pass the butter, please! Read more

Science Fair Project Idea
Expanding gases are everywhere, from the kitchen to the cosmos. You've tasted their pleasures every time you've eaten a slice of bread, bitten into a cookie, or sipped a glass of soda. In this chemistry science fair project, you'll capture a gas in a stretchy container you're probably pretty familiar with—a balloon. This will allow you to observe the gas expansion and contraction as the temperature changes. Read more

Science Fair Project Idea
thumbnail Big, puffy, cotton-like clouds, and the bubbles in a pot of boiling water may not seem like they have much in common, but they do—both are formed by a heat-transfer process called convection. Warmed gases and liquids rise, while cooler ones fall, creating currents and mixing things up. Whether making processed foods in a factory or making plastic or metal parts, knowing how to mix up a big tank of hot and cold liquids or gases quickly is important. Engineers must rely on experimentation… Read more

Science Fair Project Idea
thumbnail Have you ever left your bike outside in the rain? If so, you might have discovered unpleasant surprises afterwards—reddish-brown patches, known as rust, and your wheels, brakes, and gears might have stopped working so smoothly. In this chemistry science fair project, you'll learn why rust, a type of corrosion, is a serious problem. You'll also discover that not all rains are the same! Find out which ones can speed up the rusting process. Read more
