Make String from Algae

STEM Activity

224 reviews

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

Is the Egg Raw or Cooked? That is the Question!

STEM Activity

6 reviews

Have you ever found an egg in your refrigerator and wondered if it was cooked? Although eggs drastically change inside their shells when cooked, it is still remarkably difficult to distinguish a cooked egg from a raw one without cracking it open.

It’s About Time….To Make A Sundial!

STEM Activity

6 reviews

Have you ever watched an old movie, and when a character asks what time it is the other characters all look at the sky, instead of checking their watches, or their cell phones? There’s no giant digital clock in the sky, those characters are using the position of the Sun in the sky to tell time, as people have done for generations. The oldest known instruments for telling time, the sundial, allow us to track the position of the sun more accurately. Up until the early 19th century, sundials… Read more

Lift a Load using Liquids

STEM Activity

11 reviews

No one, not even a very strong human, is strong enough to lift a truck. However, our brains are smart enough to create a tool that can lift heavy objects for us: hydraulic lifts! You find them in body shops, on skyscraper construction sites, in wheelchair lifts, and in dentist chairs, and you will even build one in this activity! Try it out and discover how much more you can lift. Read more
