Did you know that the seaweed you've seen in the ocean or even eaten as a snack is inspiring innovators to imagine new materials? Large brown algae, like kelp, contains polymers—long chains of molecules—that are more environmentally friendly than the ones in most plastics. These natural polymers (alginates) could eventually be used to create sustainable everyday objects. Try your hand at using a bit of chemistry to turn biodegradable polymers from algae into your own custom… Read more

It’s easy to take our clean water for granted, we’re so used to being able to drink from a fountain or faucet whenever we’re thirsty. But did you know that over 1 billion people in the world don’t have access to clean water? Part of the problem is that cleaning (or purifying) water is not an easy task. Not only do you need to remove dirt and other debris, you also have to get rid of all the invisible bacteria and micro-organisms that can make people sick. In this… Read more

Have you ever watched a train roll by? If so, you might have wondered how the train is able to stay on its tracks. The secret lies in the train's wheels. Although they seem cylindrical at first glance, when looking more closely you will notice that they have a slightly semi-conical shape. (Of course, never get close to a working train!) This special geometry is what keeps trains on the tracks. In this activity you will put different wheel shapes to the test to find out why the conical wheel is… Read more

Have you ever used a crazy straw? Some spiral their way up. Others have fancy colors or decorations. Some are thin and others are wide. But just about all of them leave you sipping your drink from about the same distance. Why? Wouldn't it be fun to poke your head out of an upstairs window and secretly take a sip from a drink way below? Would it even be possible? With this activity, you'll see if you can set your own record for the longest working straw! Read more

Can you imagine a bouncy ball bouncing back and forth between two walls, infinitely?  Wouldn’t that be amazing? What if, instead of a ball, light was bouncing between two mirror walls; would it bounce back and forth forever?  Imagine each light bounce added one reflection of you in the mirror; would it look like there were an infinite number of “you’s” in there?  Can we create an infinite number of reflections? Try this activity and be amazed by the many… Read more

As more people start living and working in space, we have to design our crew capsules and space habitats to keep people comfortable. That doesn’t just mean comfy beds and space sweatpants but also includes what our work environments and new homes will sound like on the inside. First, astronauts have to get to space using rockets, which generate a large amount of noise inside the crew capsule. Once they’re in space, astronauts are busy tending to many tasks. They perform daily tasks including… Read more
