In Friction, two young islanders, Olive and Troy, are delivering mail with a mammoth-drawn wagon when they learn how important the force of friction is as they attempt to slow down! Applying what they discover about friction, Olive and Troy test a variety of brakes, trying to find the type just right for them. Even with proper brakes, it does take some time to come to a stop, though. Young Troy and Olive find this out as they join their two delivery mammoths for an unscheduled bath after a foiled attempt to stop quickly!
In Flight, inhabitants of Mammoth Island attempt to use a trusty mammoth to deliver canvas awnings when a gust of wind creates quite a stir! The islanders discover that the power of the wind, combined with the unique shape of the awning, is able to overcome the considerable weight of the mammoth, lifting it up into the sky like a kite. As soon as the wind dies down, however, the mammoth returns to Earth with a crash. The islanders begin experimenting and eventually come up with the right combination of the four forces involved in flight: gravity, lift, thrust and drag. Balancing these forces allows them to harness the power of the air and take to the skies!
Disney Educational - Bill Nye The Science Guy: Spinning Things
Many things spin, including bike wheels, frisbees, storms, hard disks, and the Earth. The standup scientist shows how it is hard to stop some things from spinning, and how a spinning object can push back when poked with a finger. Bill Nye continues to relate science concepts to student experiences, helping them to understand complex material. Bill Nye the Science Guy: Spinning Things offers clear explanations illustrated with memorably silly, but useful, graphics, and a music video.
Fungus feeds off of other living organisms and therefore grows on them. Mushrooms, yeast and mold are examples of this simple organism. How do they come to be and how do they affect us? Learn how fungi release chemicals to digest the substances they live off. Discover some of the unique uses of things like yeast and mold for food and medicine.

When the farmer's away, all the animals play ... and sing, and dance. Eventually, though, someone has to step in and run things, a responsibility that ends up going to Otis, a carefree cow.
