At the Waterworks

This book is an installment in The Magic School Bus series, which follows Ms. Frizzle and her class on various scientific field trips. While each book presents a self-contained adventure focused on a specific scientific concept, they feature the same beloved characters and educational approach.

The book focuses on the water cycle and the processes involved in water purification and distribution. Readers learn about evaporation, condensation, precipitation, and how water travels from natural sources through treatment plants to household taps.

The story and its scientific themes were adapted into an episode of The Magic School Bus animated television series. The episode closely follows the book's narrative, bringing the journey through the waterworks to life visually.
