Fasten your seatbelts everyone, and Join Ms. Frizzle and her class as they go
on a field trip to explore a volcano. Explore inside the bus as well – click
on the globe to learn about major volcanoes from around the world; click on
the puzzle piece to play a jigsaw mini-game. The plants take you to a desolate
volcanic island that you can “green” up by planting trees and flowers and
building a house. The magnifying glass will teach you new facts about all
kinds of volcanic rock; you can make your own volcano and watch it blow and
you can compare four large volcanoes in various ways.

Outside the bus you will learn about the scientific instruments used in
measuring volcanic activity and predicting eruptions, watch an island being
formed, and view pictures by clicking the camera. Click on the little yellow
bus symbols and find mini-games; in Rub-a-dub-dub Sub you’ll navigate a
submarine under the ocean with the mouse, trying to avoid dangerous enemies;
in Leaping Lava, you’ll jump the bus over a lava flow by leaping on rocks and
debris.
