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

Build a Rubber Band-Powered Car

STEM Activity

605 reviews

Admit it, you've probably launched a rubber band at least once—pulled one end back, and let it go flying. Did you ever suspect that rubber bands could also be a fun way to learn about physics and engineering? Find out in this project where you'll build a rubber band-powered car. Read more

Measure Photosynthesis with Floating Leaves

STEM Activity

231 reviews

Do you know how plants get the energy they need to grow and reproduce? They do not eat like humans and animals do; they make their own food with a process called photosynthesis. During photosynthesis, plants convert light, water, and carbon dioxide from the air into oxygen and sugars. In this activity, you will be able to observe the oxygen production in leaves by doing a floating leaf disk experiment. You can also find out how quickly plants produce oxygen, and what variables affect… Read more

Alka-Seltzer Science: The Effect of Temperature on Reaction Time

STEM Activity

139 reviews

Have you ever wondered why bubbles form when an Alka-Seltzer tablet is put in water? If you’ve ever tried it, you’ve seen that the tablet fizzes furiously when dropped into water. The moment the tablet starts dissolving, a chemical reaction occurs that releases carbon dioxide gas. This is what the bubbles are. Some factors can change how quickly the carbon dioxide gas is made, and consequently affect how furiously the tablet fizzes. In this activity… Read more

Walking Water
