ROCHESTER, Minn. - The fidgety boys and girls in Phil Rynearson's classroom get up and move around whenever they want, and that's just fine with him.

In fact, stretching, swaying and even balancing on big wobbly exercise balls are the point of this experimental classroom. The goal is to see if getting children to move even a little can help combat childhood obesity.
