This activity describes some simple, yet impressive gyroscopic demonstrations using only a bike wheel with a quick-release hub. Then, itIt explains both the angular momentum principle that tends to keep the wheel in a rigid plane and the effects of the external forces that create precession. And all without a single equation!No equations are used during the activity. Understanding the forces at work ... Full description.

As students tour this online Infrared Zoo, they gather new information about the animals they would not get from a visible light picture. Infrared light shows us the heat radiated by the world around us. By viewing animals with a thermal infrared camera, we can actually see the differences between warm and cold-blooded animals. Infrared also allows us to study how well feathers, fur and blubber insulate ... Full description.
