Science Fair Project Idea
thumbnail Have you ever eaten half an apple and saved the other half for later, only to find that, by time you were ready to eat it, the apple did not look as tasty anymore? It may have turned brown and shriveled, and, if left out long enough, it may have spoiled. Do you think you could have prevented the other half from spoiling, or made it spoil less, if you had stored it differently, such as in the refrigerator in a food wrapping? In this cooking and food science project, you will investigate which… Read more

thumbnail Animals survive in all sorts of extreme environments, whether it is a polar bear out and about when it is -40°F, a desert iguana trying to find food as the temperature rises to 110°F, or a deep sea anglerfish living 3281 feet down into the sea. How do they do it? The answer is adaptations! Their bodies have special features that allow them to live in those environments. You might not be able to dive down 3281 feet to observe the deep sea anglerfish, but in this science fair project you… Read more

thumbnail "What?! Many of my toys are also machines?" That's right—simple machines! Simple machines are everywhere! Under your feet when you climb stairs, in your hand when you use a utensil to eat your dinner, even in your arm when you throw a ball. Come visit this science fair project and explore the six types of simple machines. Find out how many are hiding under the hinged lid (yes, another simple machine) of your toy box! Read more

thumbnail Watch out! It's Eddy Vortex, Superhero! He swirls, he tumbles, he churns up air and water! OK, maybe eddies and vortices aren't exactly superheroes, but they are powerful regions of air and water flow that you have to watch out for in some surprising places. Try out this science fair project to discover why, as well as where and how to find them. Read more

Science Fair Project Idea
thumbnail When someone yells, "Think fast!" and throws you a ball, are you able to catch it? When the bell rings at the end of class, are you the first one out of your seat? Can you make it through a sudden hairpin turn in a video game without crashing? If so, then you likely have quick reaction times. In this science fair project, you'll look at reaction times (how fast people react to sensory events), and see if people who play video games have faster reaction times than those who do not.

thumbnail Soap comes in many varieties and forms—from bars to bottles to boxes. The uses for soaps are just as expansive—from cleaning our hands, hair, and faces to a variety of household cleaning jobs, such as dishes or laundry. One thing all these different soaps have in common is their chemical origin; they were all made by mixing fat or oil with a strongly basic solution, such as lye. In this chemistry science project, you will carry out the chemical steps needed to transform coconut oil… Read more

thumbnail Have you ever wondered what a wildlife biologist does? Ronnie and Denise from DragonflyTV found out firsthand when they worked with a local wildlife biologist to take a survey of the fish populations in their local lake. They wanted to determine what the biodiversity (number of different species in a habitat) was like so that they could find out how healthy the lake habitat was. In this science fair project you can take on the role of a wildlife biologist by examining the biodiversity of… Read more
