Science Fair Project Idea
You're at the high school football game and it's getting pretty chilly as the sun goes down. You're determined to keep cheering for your team, but your hands are freezing—have you ever tried hand warmers? The chemistry within these little packets is pretty cool. Hand warmers provide a unique and fun way to study the chemistry of crystal formation and heat generation. By pressing a button in a pouch, which contains a supercooled solution, you start a rapid exothermic (heat-producing)… Read more

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

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 Have you ever had a refreshing bath using a bath bomb? A bath bomb is several ingredients mixed and molded into a shape, which becomes fizzy when it touches the water. It can be quite a relaxing experience, especially if your bath bomb has a nice fragrance or includes some bath salts. The fizz is the result of a chemical reaction taking place between different ingredients within the bath bomb. In this science project, you will get to make your own homemade bath bombs and explore how changing… Read more

Science Fair Project Idea
thumbnail Fresh strawberries and summer just go together. Walking through the local farmers' market on a warm day, the bright, red strawberries call out to you, beckoning you to buy them and take them home. The next day, as you get ready to savor the delicious berries, you notice that yesterday's juicy, red strawberries are now covered in...eewwww, mold! In this cooking and food science fair project, you will investigate thermotherapy and whether this technique can preserve strawberries and prevent mold… Read more

Science Fair Project Idea
thumbnail Physicists sometimes study matter under extreme conditions. For example, think of the emptiness of interstellar space vs. the unimaginable crush of pressure at the center of a neutron star, or an object dipped in liquid nitrogen vs. the tiles on the space shuttle during re-entry. Here's an experiment on permanent magnets in "extreme kitchen" conditions that you can try at home. Read more

Science Fair Project Idea
When we get hot, we sweat. The physiological role of sweat is to cool us down. When the water evaporates, it removes energy from our bodies. This sort of evaporative cooling can also be used to cool homes, using what are referred to as swamp coolers. Evaporative cooling is also a potential source of energy waste in the kitchen because it increases the time it takes to heat water. In this chemistry science fair project, you will study how a variety of things cool down, whether for better or… Read more

thumbnail Do you know why enzymes are oftentimes called the workhorses of biochemistry? It's because they can speed up a wide variety of chemical reactions, and chemists and biologists use enzymes to do all kinds of jobs. In this project, pectinase, an enzyme frequently used in the food industry, will be used to extract juice from apples. 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
