The class is turned into insects to learn about them.

Insect invaders may be small in size, but the problems they cause are huge! Find out why and how insect invasions occur and what we can do to help. This title supports NGSS standards for Earth and human activity.

Watch out - the mad scientist has unleashed havoc on the world. The mutant bugs he created have escaped, and it's up to children to capture the icky insects and blast them off to outer space forever. Run through the junkyard, in and out and around the tires, and dash into a house under buggy siege. Quick....grab them in the classroom, snatch them in the swamp, and follow them all across town. They're slinky, they're slimy, but they're not smarter than you: there the rocket awaits, its hatch open to trap the invaders. Herd them inside--BOOM to the moon!

When Wanda brings her pet ladybugs to school to learn how to take care of them, Ms. Frizzle decides to teach the class about insects, and soon the entire class learns many surprising things about the insect world.
