My name is Ralphie. I am one of the kids in Ms. Frizzle’s class. Maybe you’ve heard of Ms. Frizzle. She takes us on lots of field trips in the Magic School Bus. We never know what’s going to happen when we get on that bus, but we do know that we’ll learn about Ms. Frizzle’s favorite subject-science! Once Ms. Frizzle took us all over the U.S. looking for bats. We thought she was batty! But then we found out some really amazing things about bats, like what they eat, where they live, how echolocation works, and lots more bat facts and bat myths. In this book, I tell you everything that happen on that trip, the time we learned The Truth about Bats.
