The Magic School Bus at the Waterworks

This is the very first book in the celebrated series. When Ms. Frizzle's class takes a field trip to the local waterworks, they don't just walk through the building—they travel through the entire system! The students shrink to the size of raindrops, fly into a cloud, and rain down into a reservoir. From there, they journey through the purification process, including filtration and disinfection, until they eventually splash out of a school sink. It is a brilliant way to explain how cities provide clean water to homes and schools.

Age Category: 7-9 Lower (Perfect for primary students as it introduces environmental science and engineering concepts through an imaginative narrative).
