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

Have you ever wondered why your phone, computer, or a flashlight works without being plugged into a power outlet? Where does the electrical energy come from that makes all these portable devices function? You probably know the answer: they use batteries! But do you know how these batteries work? Batteries store electrical energy in the form of chemical energy, which means that electrochemical reactions inside the batteries create electricity. It may sound complicated, but it is simpler than you… Read more

Have you ever imagined yourself falling asleep on a cloud? Did you know that if you were to sleep in a cloud, you would wake up soaking wet!? There are many different types of clouds, but one thing they have in common is that they’re all made of water (or ice). But how do clouds form, and how is it possible that water can float above us in the air? In this experiment you’ll make your own cloud in a jar, and get to test the conditions that are required to make a cloud… Read more

Have you ever wished you could copy a drawing but make it larger or smaller? If you've tried to create a larger or smaller copy of your work, you've probably realized that it is very hard to get the details right. A machine called a pantograph, however, could help. It makes copies that can be scaled up or down or made the same size. In this activity you will make your own pantograph and then duplicate your drawings. Can you figure out how it enlarges, shrinks or turns drawings upside down? Read more
