Make String from Algae

STEM Activity

230 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

Balance the Forces Within a Mobile

STEM Activity

31 reviews

Have you ever seen a mobile? Not a mobile phone, but a hanging art sculpture. You might have had such a mobile in your room when you were little. These mobiles hang from the ceiling and are usually made up of many layers of rods to which lots of differently shaped objects are attached with strings. When you look at the mobile sculpture, you might wonder how it can stay balanced all the time even when it is moving in the air. In this activity, you will make your own mobile sculpture and find out… Read more

Balloon Magic with Bernoulli's Principle

STEM Activity

42 reviews

Have you ever seen pictures or videos of a roof being blown off a house during a hurricane or tornado? You might be surprised to hear that the roof is actually not pushed off by the strong winds but instead by the air inside the house! This can be explained by Bernoulli's principle, which states that fast-moving fluids or air, such as strong winds, have lower pressure than slow-moving air. In this activity you will demonstrate how balloons can be moved in a similar way. It is not quite as… Read more

Bridge Building Bonanza: Which Design Wins?

STEM Activity

57 reviews

Have you ever ridden in a car driving across a suspension bridge? Suspension bridges, with their tall towers, long spans and gracefully curving cables, are beautiful examples of the work of civil engineers. How do the cables and towers carry the load that is on the bridge, which includes you and the car you are in when you cross the bridge? Can a suspension bridge carry a greater load than a simple beam bridge? You can try to answer these questions in this science activity! Read more
