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.
On the first Friday evening of each month from October through March, a different astronomer presents a special topic and answers your questions. If skies
are clear, be ready to go outside and view the night sky (bring your own binoculars or telescope to share).
Students ages 10 and up can earn their Junior Astronomer certificate and astronomy supplies when they attend a minimum of 4 programs and write a brief synopsis. All Jr. Astronomers will receive recognition in March.
