Streets, buildings, and parking lots can get so hot that they raise the average temperature of urban areas by a few degrees. Do you think natural materials also heat up in the sun, or only man-made materials? Do this activity to find out! Read more

This phenomenon can be a nuisance when you want to fill silos, bags, or bins with different types of materials. It can also be used to our advantage: an avalanche airbag uses the… Read more

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

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

Have you ever opened a fresh bottle of carbonated water or soda, poured a glass of it, and just watched as the bubbles fizzed upward in the glass? Have you ever wondered what those bubbles are? They're made of carbon dioxide gas, which was packed tight in the soda before you opened the bottle. Not only can that carbon dioxide gas give you a fizzy drink to enjoy, but it can also give you a show. How? By making candy conversation hearts "dance!" Along the way you will discover some of the fun… Read more
