Back Down2Earth Booklet
Back Down 2 Earth (BD2E) is an expansion of the existing Down 2 Earth (D2E) education project which teaches school students aged 11-19 about the geological side to astronomy. In this 46-page booklet you will learn about the wonders of comets and asteroids and the possible destruction that these bodies can cause on planets such as our own.
View this as a web-page (some material omitted).
