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
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

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 In this project, you'll learn how to isolate DNA from onion cells, separating it from other cellular components in a manner that still preserves its structure and sequence. In the end, you'll have enough DNA to see with the unaided eye, and you'll be able to spool it to demonstrate its strand-like structure. Read more

Science Fair Project Idea
thumbnail Crystals come in all different shapes and sizes. However, the purest and cleanest crystals are usually also the ones that grow to be the largest in size. In this science fair project, you will compare the size and shape of crystals grown in three different temperature conditions: room temperature, in the refrigerator, and in an ice bath. With just water and borax, a household cleaning product, you can discover the best recrystallization method for growing large, pure crystals. Read more

Science Fair Project Idea
thumbnail Everyone knows electricity can create heat, especially because our electrical appliances tend to warm up when turned on. But wouldn't it be cool to do the reverse — generate electricity from heat? In this science project, you will study why it happens, measure the effect, and then use the phenomenon to build your own device, a thermocouple thermometer, that will enable you to convert heat into electrical energy.

Science Fair Project Idea
thumbnail You may be familiar with permanent magnets—the kind that hang on a refrigerator. But did you know that other magnets, called electromagnets, can be turned on and off? When turned on, electromagnets act just like permanent magnets, but if you turn them off, their magnetic properties disappear. Electromagnets are an important part of many electronic devices, like motors, loudspeakers, and hard drives. You can create an electromagnet with a simple coil of wire and a battery. In this science… Read more

thumbnail "Slurp...plop!" Recognize that sound? You might if your family usually serves jellied cranberries for the holidays. Jellied cranberries are thick, like gelatin, and retain the shape of the mold in which it was placed, which might mean Aunt Sue's turkey mold or even the shape of the can if you buy one of the popular canned versions. Taking a bite of wiggly jellied cranberries can be a fun addition to a delicious meal, but cranberries can also be served as a sauce. Both versions use the same… Read more

Science Fair Project Idea
thumbnail Have you ever noticed that when you drop a basketball, its bounce does not reach the height you dropped it from? Why is that? When a basketball bounces, such as on a basketball court, its bounce actually loses momentum by transferring energy elsewhere. This means that to dribble the basketball, players must continually replace the transferred energy by pushing down on the ball. But what happens to the "lost" energy? As we know from physics, energy is not really lost, it just changes form. One… 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
