The Magic School Bus Flexes Its Muscles
Field Trip Notes
Ralphie's bored with chores, so he daydreams about building a robot to do his tasks. Before he can start, the Magic School Bus's mesmerglobber blows a gasket. At the body shop, Ralphie and the kids use spare parts to build a Ralphiebot. But the robot doesn't move! By trial and error, the kids learn that everything 'hinges' on understanding how their own bodies move. They use parts that are like bones, joints, and muscles to get Ralphiebot working. But now the giant robot is out of control! Can Ralphie take Rapphiebot apart before he destroys the body shop?
