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

Collide Head On with this Toy

STEM Activity

Did it ever occur to you that tennis, bowling, Newton’s cradle, and cars bumping into each other all revolve around collisions? It is fascinating how a few rules of physics can predict the outcome of these collisions. You can discover these rules yourself with a fun homemade toy. Do the activity, play with the toys you make and be one step closer to understanding what happens when you shoot a marble into another! Read more

Have you ever thought about the sheer number of words that exist in the English language to describe sounds? A noise can be a thud, a clang, a bang, a pop, a crash, a splash, a clatter, a buzz, a tinkle, and many more! You can probably think of an example for each of these—but if you heard the sound, could you say what produced it? Read more

A hot summer day is the perfect time to go to the beach and cool down in the brisk ocean water. But it's not only the water that has a cooling effect at the beach. Have you ever noticed that there always seems to be a cool breeze blowing from the ocean to the shore? Where does the wind come from? In this activity, you will build a model of the ocean and the beach to find out—so next time you go to the beach, you will know why the sea breeze is blowing! Read more

Do you enjoy watching mysteries or crime investigation shows? Every criminal leaves behind evidence at the crime scene. The trick to catching the criminal is collecting all of the evidence and making sense of it. This is what a forensic expert does. In this bloody, Halloween-themed science activity you’ll be correlating the size of blood stains to the distance they fell, but don’t get too grossed out; you’ll be doing it with fake blood. If you like figuring out mysteries, this… Read more

Do you like gift wrapping? If you do, you have probably curled a ribbon with scissors before. Have you ever wondered why the ribbon curls when you run a scissor blade down one side of it? The answer is that when you apply pressure on the ribbon with the blade, the outer layer of the ribbon stretches and expands. This makes the outside layer of the ribbon longer than the inside layer that is pressed against the blade. As a result, the ribbon starts to curl to make up for the different lengths of… Read more

Do you like watching raindrops on your window as they move and run down the glass? It is fascinating to observe how some of them just sit there by themselves, whereas others combine to build a larger drop. Have you ever wondered what makes them move and behave in different ways? Controlling and influencing wetting, the spreading of liquids on surfaces, is actually important for many industries. For some purposes, you want a surface to repel a liquid; just think of your water-repellent jacket as… Read more
