Oxygen on Earth: A Four Billion Year History

Astronomy Series

The air we breathe is 21% oxygen, an amount higher than on any other known world. While we may take our air for granted, Earth was not always an oxygenated planet. How did it become that way? How did life come to depend on oxygen? Volunteer naturalist Beth Baker will try to explain this fascinating story in an hour. Astronomy Series meets the first Friday from October to March. If skies are clear, be ready to go outside and view the night sky. Students ages 10 and up can earn their Jr. Astronomer certificate and astronomy supplies by attending 4 astronomy programs and writing brief synopses of what they learned. Free; $5 parking for non-members.
