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
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.

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?
Did you ever notice the cool patterns around your footprints when you take a walk in the wet sand at the beach? The pressure of your feet has effects far outside your footprints. Here's a project that uses a simple experimental apparatus to investigate how the volume of wet sand changes under pressure.
Do you filter your tap water before drinking? Many commercials claim these filters make your drinking water cleaner and safer. But what, exactly, are these filters doing and is the water really cleaner afterwards? The cleaning power comes from their filling material, called activated carbon. It exists in all kind of forms: powder, granules, foams, and blocks. Do you think it matters what type of activated carbon is inside the filter? In this activity you will investigate whether larger or…
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…
Dried beans are a major ingredient in dishes served all over the world. In their dried form, they can be stored for years and then "brought back to life" by soaking them in water. In this cooking and food science fair project, you will measure just how much water is absorbed by beans when they rehydrate (soak up water). Can such a little bean really hold that much water?
Doctors use many complicated tools to check the health of patients. But you can make some medical tools at home—like a stethoscope! A doctor uses a stethoscope to listen to a patient's heart. In this science project, you will make three of your own homemade stethoscopes and figure out which stethoscope design works best and why.
You have probably seen it on You Tube™ — the exploding Coke® and Mentos®
experiment. But what is it that makes the reaction happen, and what factors cause a larger or smaller
eruption? In this science project, you will see if using crushed
Mentos candies, instead of whole Mentos candies, will affect the reaction.
Comets—big lumps of rock, ice, and frozen gases that orbit the Sun—are among the most amazing
heavenly objects seen in the night sky. The glowing tail behind the comet's nucleus inspires wonder.
But did you know that a comet's tail is evidence that it's melting? As a comet passes by the Sun on
its orbital path, it starts to melt. But do bigger comets melt faster than smaller comets? In this
astronomy science project, you will investigate how the size of the comet affects the…
