Have you ever poured sand out of a bucket, or poured cereal out of a box, and noticed it is a lot like pouring water? It is because sand and cereal are granular materials. This means they are made up of solid particles, but they can actually flow like liquids! Candies, like Skittles®, M&M's®, Nerds® candies and many others, are also granular materials. In this science activity, you will investigate how the size and shape of granular materials affect how they flow. And what… Read more

As Valentine’s Day approaches, we’re increasingly confronted with stylized images of the heart. Real hearts serve very important functions – a person’s heart beats to supply blood to their entire body, and the heart has to work harder when they exercise. Have you ever wondered how quickly your heart beats when you exercise, or how long it takes to recover back to its normal rate after you’re done exercising? In this science activity, you’ll get to do some… Read more

Have you ever let a map spur your imagination, wondering how life was as a world explorer sailing the oceans in search of new land? Maybe you see yourself drawing a map of your new discoveries. Wait a minute – you just realize Earth is round, so how do you create an accurate flat map? Throughout history, cartographers all around the world have found different methods for creating flat maps of Earth. None can represent reality exactly, but each is useful for specific purposes. Do this… Read more

Catch the Wave!

Science Fair Project Idea

Scientific Method

There is a lot of energy that can be harvested from moving water. Energy can be extracted from water rushing over a waterfall and from the regular patterns of the ocean's tides. The energy that propels waves forward in the oceans can also be extracted and used. But can wave energy power plants be built anywhere there is water? In this energy science fair project, you will use ocean buoy data and mathematics to determine which locations along the coasts of the United States can sustain a wave… Read more

Changing Constellations

Science Fair Project Idea

Scientific Method

Do you like to look up into the night sky? There are so many stars, it can be mind boggling! Some ancient people marked time by the changes in star patterns. We still use changes in constellation patterns to mark astronomical time. Do constellations change more in one hour, one day, one month, or one year? Read more
