Science Fair Project Idea
Scientific Method
If you leave an ice cube out on the kitchen counter and come back to check on it in awhile, what do you find? A puddle! The same thing happens to ice in nature—if the temperature gets warm enough, it melts. In this ocean science project, you will find out what happens to sea levels if the ice at the North Pole melts, or if the ice at the South Pole melts. It is an important question for the millions of people who enjoy living along the coasts of the world. Read more

Scientific Method
Have you ever wondered how a chick breathes inside its shell? Every animal needs oxygen to survive, so the chick must get air somehow! Try this science project to discover the answer. Read more

Scientific Method
How much iron is in your cereal? In this experiment, you will devise a way of testing foods for supplemental iron additives. Then you will use your design to test different breakfast cereals to see how much iron they contain. Which brand of cereal will have the most iron in it? Read more

Scientific Method
Fuzzy things are often cute, but not when that fuzziness is mold on your strawberry—yuck! Companies look for natural, plant-based ways to protect the berries from mold when they are in the store, waiting for you to purchase them. Would washing them in aloe vera juice protect strawberries from mold? Do this project and find out! Read more

Scientific Method
Electricity powers many of the devices we use every day, from lights to video games and computers. Engineers have to use certain materials to make electrical devices work. In this experiment, you will find out which materials let electricity flow through them (conductors) and which ones prevent electricity from flowing through them (insulators). Read more

Scientific Method
Do you think worms are gross? Or that they are only good for birds or fish to eat? Well, in this zoology science project, you will find out that this lowly animal helps to put food on your table, too, by all the hard work that it does in the dirt. In this science project, you will discover in what kind of soil it likes to do its work. It is wiggly good fun! Read more

Scientific Method
In this fun science project, you will create a bird feeder from recycled materials that you can set up outside. By observing the birds that come to the bird feeder, you will find out what different kinds of birds live in your area. How many different kinds of birds do you think you will spot? Read more

Scientific Method
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

Scientific Method
Have you ever stood close to a fossilized T. rex skull and counted its razor-sharp teeth? Or, have you seen a fossilized stegosaurus skeleton and thought about how it defended itself with tail spikes and armored plates? A trip to a natural history museum lets you imagine what dinosaurs looked like and wonder what life with them on Earth was like. Fossils give us information about animals and plants that lived long ago. Certain places around the world contain more fossils than others. Why?… Read more

Scientific Method
Have you ever been to the Grand Canyon and seen what water can do over millions of years? When you turn on the faucet, do you see water come out, or mud? In this experiment you'll find out how engineers help prevent erosion, which keeps dirt out of our water. Read more
