Design Your Own Slime

Science Fair Project Idea

Engineering Design Process

There are many different kinds of slime out there. Some slime is runny and liquid-like; other slime is thick and rubbery. Some slime glows in the dark, some is fluffy, and some is even magnetic! What set of properties makes the best slime? What kind of slime would you choose to make if you were selling slime as a toy in your own "slime shop"? In this project, you will experiment with different slime recipes and try to perfect one to make slime with the exact properties you want! Read more

Have you ever wondered what makes a paper plane fly? Some paper planes clearly fly better than others. But why is this? One factor is the kind of design used to build the plane. In this activity, you will get to build a paper plane and change its basic design to see how this affects its flight. There is a lot of cool science in this activity, such as how forces act on a plane so it can fly, so get ready to start folding! Read more

Which Filtration Material Leads to the Best Drinking Water?

Science Fair Project Idea

Scientific Method

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 afterward? The cleaning power comes from their filtering material, called activated carbon. It exists in various forms: powder, granules, foams, and blocks. Do you think it matters what type of activated carbon is inside the filter? In this project, you will investigate whether larger or smaller… Read more
