In 1991 Richard Dawkins made a series of five one hour presentations discussing evolution called Growing Up in the Universe. The presentations are interesting and visual and aimed at young people, but as an adult I found them quite interesting myself. I have collected the links together here:
Growing Up In the Universe (Google Video)
- Waking Up In The Universe
- Designed and Designoid Objects
- Climbing Mount Improbable
- The Ultraviolet Garden
- The Genesis of Purpose
I hope you enjoy them with young people.
