Volcanoes on the planets! What kinds of eruptions occurred on other planets?

Exploratour -Volcanoes of the Solar System

Suggested Activity: Use the jigsaw technique with groups of three or four students to investigate volcanoes on other planets and moons.  This works best after learning about the different types of volcanoes that occur on Earth.  Students can choose (or be assigned) a particular planet or moon to investigate in detail.  The individual student task is to investigate the variety of volcanic landforms on their particular planet and to determine what is similar and what is different compared to those on Earth.  The "experts" then meet to share their detailed knowledge, and then the base group convenes so that each expert can share what they've learned and to create a final report on the variety of volcanic landforms in the solar system. The criteria for the activity can be tailored to grade or course level. This can be followed with the activity "What factors influence the shapes of volcanoes?" to help students investigate the influence of gravity on volcanic landforms.
