This activity introduces students to planetary research. Students learn to focus on details by studying and writing descriptions of uncaptioned images of the Solar System. They then increase their knowledge of the planets and their features by comparing their descriptions to those of real researchers. Students organize their findings to infer a key difference between inner and outer planets. Full description.

In this lesson, students focus on the tremendous public interest in the potential of extraterrestrial life. Students read and discuss an article about the search for alien life. They then divide into small groups and discuss the issues and implications of this search. Finally, they write about the complex issues involved in this search and its implications in one of several suggested genres. Full description.

This article discusses the possibility that water might exist on the Moon. Topics include some uses for water in space (other than drinking), where the water might be found, and the idea that it may have been 'delivered' to the Moon by comets, which are largely made of ice. Full description.

NASA Investigators working with Mars Odyssey data may have discovered remnants of snow packs that have created a system of gullies in crater walls and other, more unusual places such as ridge crests, sand dunes, and hilltops. Readers of this journal article can learn about the snow packs and their potential to collect and shelter water beneath themselves, possibly providing a favorable environment ... Full description.
