Science Fair Project Idea
thumbnail What do sand and cereal have in common? They are both granular materials, which means they are made up of solid particles, but they can actually flow like liquid. When two granular materials with very different-sized particles are mixed, you can actually separate each type by putting them in a rotating device called a tumbler. In this science project, you will examine how common household granular materials behave when mixed together in a moving container Read more

thumbnail In the wild there are two types of animals: the hunters and the hunted. A good predator is always on the prowl for fresh prey. What can an animal do to stay off of the menu? To survive, some animals use camouflage so they can better blend in with their surroundings. In this science project, you will be the hungry predator hunting for M&M® prey. But it may not be as easy as it sounds — some of your prey will be camouflaged by their habitat. Will they be able to avoid your grasp? … Read more

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 Imagine that you want to create your own brand of colored candies. You know they would be a success if only you could figure out how to make a certain color, such as purple. How can you do this when government regulators have approved just a few food dyes? First, you will need to find out how your competitors make all of their colors from these few dyes. Do different candy brands use the same or different dyes? This can be figured out with gel electrophoresis, a technique commonly used in… Read more

thumbnail Rockets are definitively an engineering challenge. These amazing gravity-defying machines have lifted test material, people, and even animals into space. Feel like building one yourself? In this science project, you will transform a water bottle into an aerodynamic bottle rocket with two compartments, one for the fuel and one for a payload. You will then test how well it performs when lifting mass vertically up into the air. Ready, set, soar! Read more

Science Fair Project Idea
For many kids, a day at the beach would not be complete without building a sandcastle. Have you ever wondered how it is that you can pack sand into a mold for a sandcastle? Do some kinds of sand pack better than others? This project will show you how to measure the porosity of sand: how much air space there is in between the sand grains. Maybe you can use your knowledge from this project to help you make bigger and better projects with sand. 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
