Ms. Frizzle's class is learning all about water. And when Wanda suggests they take a tip to Waterland, Ms. Frizzle gets a funny look in her eyes. But insead 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!
