Science Fair Project Idea
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
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
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
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

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
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
