What's in a Tail? - Everybody seems enamored with their tails today, except for Max, who doesn't think his tail is so special. Mama shows the kids (through her movies) that there are a lot of different "tails to tell" in the animal kingdom. Every tail, however, is unique and special - just like the animal it's attached to. Footprints in the Sand - Playing in the bush, Max, Bo and Karla stumble upon a giant footprint, and go running back to Mama. Mama is curious, and together they discover (by looking at movies of various animals and their "tracks") that the print they saw wasn't left by any animal walking in the savanna today but, instead, was left by an impressive remnant of the distant past.

The flapping of a butterfly's wings over Bermuda causes a rainstorm in Texas. Two sticks start side by side on the surface of a brook, only to follow divergent paths downstream. Both are examples of the phenome non of chaos, characterized by a widely sensitive dependence of the fu ture on slight changes in a system's initial conditions. This unit exp lores the mathematics of chaos, which involves the discovery of struct ure in what initially appears to be random, and imposes limits on pred ictability.

This episode of "GED Connection" covers measurement. It goes over the units of measurement that we use, when we use them, and how they're co nverted to other forms of measurement. It is explained that useful con versions will be supplied on the GED test for those who take it but th at it's a good idea to commit them to memory anyways. The program take s a look at workers on a construction site as they use a tape measure to figure out feet and inches, a landscape architect as she figures ou t the area and volume of the space she is working on, and an architect as she explains the importance of volume and cubic feet and yards. Th is program also covers the benefits of the metric system.
