Build a River Model!

STEM Activity

118 reviews

Earth is a very watery place! More than 70% of the Earth's surface is covered by water. This is due to the many water bodies that can be found everywhere on our planet. What types of water bodies do you know? They are all very distinct from one another in their appearance, size, shape, and movement. In this activity, you will explore the distinct characteristics of a river by creating a river model inside a pan with sand, pebbles, and real water! After that, you can continue to model other… Read more

Make String from Algae

STEM Activity

225 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

Fruits Gone Bad? Discover Enzymatic Browning
