Magic School Bus Science Chapter Book #15.

"Hi, I'm Dorothy Ann, one of the kids in Ms. Frizzle's class. When we started learning about volcanoes, I thought we'd just be studying them in books -- but Ms. Frizzle had other ideas. She took us all the way to Hawaii, where we waded through lava and saw a real volcano blow its top. We had a great time -- even though the trip was sometimes almost too hot to handle! One thing's for sure: This was one explosive adventure that none of us will ever forget!" -- Back cover.

The Magic School Bus blasts off on a tour of the Milky Way planets, and the kids discover how the other planets are different from Earth. Not only do they all have different temperatures, but each planet has a different atmosphere as well. Ms. Frizzle's class finds out how far away the planets are, and how long it would really take to get there if they didn't have a Magic School Bus.

When their class project for Ocean Awareness Day falls into Ms. Frizzle's fish tank, Tim and his classmates board the Magic School Bus with their teacher for a real underwater adventure.

Ms. Frizzle's next lesson takes her students on a magic bus ride to the North Pole, where they observe polar bears and other creatures in their natural habitats.

Ms. Frizzle's students learn lessons in survival after she accidentally turns them into butterflies
