Alien Earths

This webquest introduces students to the processes of star and planet formation and the search for life on other worlds. Materials include slide shows with written narrative that explain the birth and life cycles of stars and planets, methods for detecting planets in orbit around other stars, ways of searching for extraterrestrial life, and an interactive presentation on the Drake equation, a way of calculating the odds that there are living organisms on other planets.
