Project Idea
thumbnail Measurements are very important for scientists. It is especially important that the measurements be accurate. Think about how important accuracy is when you want to know if you are taller than a friend of yours, every inch counts! In this experiment, you will investigate how different objects can be measured with accuracy. Are small or large objects more difficult to measure? Who in your family is the best at measuring? Maybe it will be you! 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

Project Idea
thumbnail How does your family thaw and cook meat? Have you ever wondered if it is the safest way? In this practical science project, you can find out and shed light on safe practices in the kitchen by investigating how many viable bacteria are present in samples of meat that have been thawed or cooked using different methods.

Project Idea
thumbnail OK, spill the beans, what's your favorite bean-rich food? Burritos? Chili? Or maybe you prefer the spicy Indian stew of lentils, known as dal? But what about fried tofu? Soymilk? Or peanut butter and jelly sandwiches? Did you know those foods come from beans as well? Beans are important to the diets of many people, and in this cooking and food science fair project, you'll learn how the liquid that beans are cooked in affects how quickly or slowly they soften.

thumbnail What do rocks and clocks have in common? Both keep track of time. Yes, radioactive isotopes present in rocks and other ancient material decay atom by atom at a steady rate, much as clocks tick time away. Geologists use those radioactive isotopes to date volcanic ash or granite formations like the giant Half Dome in Yosemite National Park. Anthropologists, archeologists, and paleontologists also use radioactive isotopes to date mummies, pottery, and dinosaur fossils. Does this sound abstract… Read more

Project Idea
You might not know it, but a lake without algae would be a very dull place. If there were no algae, there would be no small animals feeding on the algae, and there wouldn't be any fish eating the small animals that eat the algae. You might conclude that since some algae is good, more algae is even better, but algae growth has a down side. If there is too much algae, they can deplete the oxygen in the water, killing off other species in the water. What is one culprit that leads to algal growth?… Read more

Safety Adult supervision is recommended.
Project Idea
thumbnail The clothes you wear are made of fibers that come from many different sources. Some fabrics are made from natural fibers, and some from manufactured or totally synthetic fibers. In this science fair project, you will explore how different fiber types react with dye. Are you dye-ing to find out which works best? Read more

Project Idea
thumbnail Gelatin! It's hard to think of another food that is used as frequently on the dinner table as off. You can find it in all sorts of sweet foods, from ice cream, yogurt, and gummy bears, to marshmallows and yellow colorings for sodas. Off the table, it shows up in glues, photographic paper, playing cards, crepe paper, medicine capsules, hair gels, and professional lighting equipment. From the kitchen to the theater—what a range of uses! In this cooking and food science fair project, you'll… Read more
