My name is Ed Pieret and I am an amateur astronomer. I am a past president and currently vice-president of the San Mateo County Astronomical Society (SMCAS).
If you are in San Mateo County in California and would like to sponsor a stargazing or educational event, please contact me at Epieret@comcast.net.
I am an active participant in Project Astro, an organization that pairs teachers with astronomers for astronomy education. The Class Topicstab contains the presentations and references for a number of recent third grade classes.
