Ms. Frizzle's class is learning all about water. And when Wanda suggests they take a trip to Waterland; Ms Frizzle gets that funny look in her eyes. But instead of taking her class to the water theme park; she takes them on a seriously wet and wild ride - through the water cycle! Join the class as they evaporate; condense; rain; and make their way back to the ocean...only to evaporate all over again!
