Science Fair Project Idea
thumbnail 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

Science Fair Project Idea
thumbnail 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

Science Fair Project Idea
thumbnail Do you think worms are gross? Or that they arere 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

Science Fair Project Idea
thumbnail Have you ever been in an earthquake? What did it feel like? Did you jiggle back and forth? Up and down? Was there a jolt? Or a rolling motion? Come build a house Hansel and Gretel would love to eat, a special table to shake it on, and see how different soil types can amplify shaking. Read more

Science Fair Project Idea
thumbnail A tsunami is a series of waves made in a body of water, like the ocean, that can cause serious destruction when they hit the coastline. In deep water, a wave can be just a few feet high and travel very fast. As it nears the coastline, and moves into shallower water, tsunamis usually slow down, but the wave height can grow to 100 feet! In this ocean science project, you will model a tsunami and investigate how wave velocity (speed) depends on water depth. Does it match the mathematical equation… Read more

Time Required Short (2-5 days)
Prerequisites None
Material Availability You will need an extra-long plastic storage box to use as a water tank. Plastic storage boxes that can slide under a bed work very well. See the Materials and Equipment list for details.
Cost Low ($20 - $50)
Safety Use caution when working with the lamp and the water tank. Make sure the two are far apart from each other at all times. Adult supervision required.
Science Fair Project Idea
thumbnail Have you ever looked in the kitchen cupboard and found a container of tiny white grains, but you were not sure if they were sugar or salt? They look very similar. How could you tell them apart? Well, you know that sugar and salt taste very different. Taste is actually called a property, and properties are used to describe and identify different materials. Properties can also be used to physically separate things. In this science project, you will use different properties to create a way… Read more

Material Availability Iron filings and neodymium magnets may need to be specially ordered. See the Materials and Equipment list for details.
Cost Low ($20 - $50)
Safety An adult's help may be needed for using a knife and scissors to cut a plastic bottle. Follow all safety precautions when handling the neodymium magnets; these magnets should never slam together, never pinch fingers or skin, never be swallowed, and should be kept away from all electronic devices. Keep them out of reach of all young children and pets. An adult should help if a stovetop or oven is used.
Science Fair Project Idea
thumbnail Living in the industrialized world, like the United States, we are fortunate because we don't have to worry about the quality of our drinking water. Your community has the means to clean and provide water to you. But in many parts of the world, people don't have this luxury. Whether it is due to war or poverty, the lack of clean water leads to many health and social problems. In this environmental engineering science project, you will learn about different methods to filter out impurities in… Read more

Science Fair Project Idea
thumbnail While trains that fly through the air might still be science fiction, trains that float just above the tracks without actually touching them are real and are actually used in a few countries today. This technology is called magnetic levitation. In this physics science project, you will build your own levitating train model and test how much weight it can hold before it stops hovering above the tracks. Read more

Science Fair Project Idea
thumbnail 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

Science Fair Project Idea
thumbnail Have you ever wondered why some things disappear when they are put in water but other things do not? For example, you may have seen that salt disappears, or dissolves, when it is mixed in a glass of water. But when you throw a rock in a stream it will not usually dissolve, and instead it will just sink to the bottom. And then there are some things that do not act like the salt or the rock. These are called colloids. If you have made Oobleck out of cornstarch and water, then you have seen… Read more
