The kids in Ms. Frizzle's class are getting ready for the Wild Weather Show. To help the kids with their projects, Ms. Frizzle takes them on a field trip to the Weatherama Amusement Park. Ms. Frizzle's class find out just how wild the weather can be when the Magic School Bus flies into a tornado. The kids learn about when and how tornadoes form, the areas in the U. S. with the worst tornadoes, and the kind of damage tornadoes leave behind. It looks like Ms. Frizzle's class is in for a whirlwind of excitment!
