Some of the activities offered take the form of educational experiments. In one, children make their own volcano by playing with two variables — the thickness of the magma, and the amount of gas — then watch how their volcano erupts. In another, kids compare different types of real-world volcanoes (like St. Helens and Mauna Loa) by taking a closer look at their features, including lava flow, sound, and ash.

Short volcano videos show lava flow and underwater smoke, and a map features 10 "clickable" volcanoes from around the world that offer important characteristics of each. The life of a volcano is demonstrated in another activity. Children can follow the stages and see how a volcano is formed and develops and, finally, what happens when it erupts.

Creativity activities allow kids to explore volcanoes in a more casual manner. Children use stickers to bring a volcanic wasteland back to life with greenery and housing. When they want to start over with a clean slate, they can do so with a blast — a volcanic one, of course!

Games include picture puzzles featuring stunning photographs of volcanoes that need to be pieced back together and an arcade-style game that plays much like Frogger, only players lead the school bus across a lava flow by strategically hopping onto logs and rescuing animals along the way for bonus points. In Rub-a-Dub Sub, kids navigate a submarine, collect rocks, and dodge assorted obstacles including heat vents and lava. Yet another fast-paced game entitled Operation Rescue requires children to guide lava down the mountain and away from the town using concrete blocks.

In comparison with the other titles in the Magic School Bus Activity Center series, Volcano Adventure seems to have more games. However, our testers missed the game show-style quizzes that appear in the previous titles in the series.

This program is fun and interesting for a time, but kids with a genuine interest in the subject will do best with the game. Because the program is rather open-ended and is missing an overall goal, children can easily avoid the educational tidbits in favor of the arcade-style games.

Technically Speaking
Minimum system requirements are Windows 98/ME/2000, Pentium 166, 16 MB RAM for Win 98 or 32 MB RAM for Win ME/2000, 4X CD-ROM, and 16-bit sound card. Mac users require an iMac, iBook, or Power PC 233 MHz or higher, System 8.1 or higher, 32 MB RAM (64 MB for OS 9.0), and 4X CD-ROM. Requires 15 MB of hard drive space. A printer is recommended.

Skills Covered
Children learn about the features and characteristics of volcanoes from around the world. They explore the life of a volcano, its components, the effects it has, and the tools seismologists use.

Educational Value
Many general science programs on the market cover broad subject matter and often give children only a superficial look at various topics. This series zeroes in on specific topics and does an excellent job of exploring these in depth. Volcano Adventure presents plenty of age-appropriate information and allows kids to do some experimenting in order to gather a deeper understanding of volcanoes. However, because the game lacks an overall goal, some children might skip the more educational portions of the program and head straight for the games.

Entertainment Value
Ms. Frizzle's trademark puns along with bright graphics and plenty of fast-paced games keep the program fairly spirited.

Design
This program is thoughtfully designed and especially easy to use. Where appropriate, the CD-ROM employs multiple levels of difficulty and the arcade games feature increasing levels of challenging game-play. Closed-captioning for the deaf and hard of hearing is easy to turn on and off.

Replayability
Though the program is enjoyable and educational, we expect average replay value. While there is adequate variety of activities, the program lacks a mission or goal to motivate children to benefit from all the information offered.

Dollar Value
This program retails for $19.95 US.
