Science Fair Project Idea
Did you know that your body has a built-in cooler? And it might not be what you think! Sweat is produced when you are hot, but its purpose is actually to cool your body as the water in it evaporates from your skin. In this science fair project, you'll use the energy produced when water evaporates to cool down chocolate-covered candy so it doesn't melt. Read more

In this project, you will make 2-dimensional templates, called nets, that fold up into 3-dimensional (3-D) shapes. By making shapes of different sizes, you will be able to see how 3-D shapes change with size. Which property (or aspect) will change the most: the length of an edge, the surface area, or the volume?

Have you heard the term windchill used before? Maybe on the TV weather forecast? The windchill factor describes what happens to an object (like your body) when it is cold and windy outside. As wind increases, heat is carried away from the body at a faster rate, driving down both skin temperature (which can cause frostbite) and eventually the internal body temperature (which, in extreme cases, can lead to death). In this science fair project, you will use a device to measure wind speed (an… Read more

Science Fair Project Idea
Has your dog ever barked, seemingly for no reason at all? Or has your cat ever stopped and carefully smelled a spot that looked perfectly clean to you? Pets, like people, have senses that they use to learn about and to react to their world, but their senses can be stronger or weaker than people's. In this mammalian biology science fair project, you'll study your pet's sense of taste by conducting taste tests and watching how your pet acts to determine his or her favorite type, flavor, or brand… Read more

Do you live in an area where the weather changes a lot from season to season throughout the year? Or do you live in a place where the weather stays pretty much the same all year long? How dynamic is the weather, and how does it compare to climate? In this experiment you can use the Internet to conduct your own investigation about how climate and weather in your local area change over time. Read more

When your parents were kids, they probably wore polyester. Static cling was a major household issue! Now everybody wears cotton, which does not get static cling nearly as much. Why are some materials more susceptible to static cling than others? Investigate how well different materials produce static electricity by making a homemade electroscope and testing it out in this science project. Read more

Science Fair Project Idea
Ever try to tear a telephone book in half? Even though you can easily rip one or a few pages to shreds, the entire phone book has strength in numbers and holds together. This project is an introduction to measuring and comparing the strength of materials. Does spaghetti get extra strength if you bundle it together, or does strength simply increase proportionally with the number of strands? If you are interested in materials testing, get cracking!

Have you ever had fun playing with sand and water, observing how little rivers you create carve their way down to the lowest point of the sandbox, backyard or beach? Some meander, others braid, and some carve a path straight down. Hyrdologists (or scientists who study water) do very much the same thing! Only they set up the model in a particular way, so observing their mini-rivers helps them answer questions about how water flow affects the environment. In this geology science project, you… Read more
