This particular Magic School Bus book is adapted from an episode of the animated TV series, and reads and looks different from the original Magic School Bus books (no side informational cartoons). Kids will learn that we hear sound when objects vibrate and that sound is dampened when vibration is hindered. Eventually the class dons magic glasses that allow them to see soundwaves. The students notice that higher sounds have waves that are close together whereas lower sounds have waves spread much further apart. The concepts aren’t difficult to grasp and the plot is entertaining.
