Teachers and Non-Profit Organizations

We conduct Earth Science Presentations for grade schools, individual classrooms and non-profit organizations free of charge.  A large collection of various rocks, minerals,  and fossils will be brought to display along with the basic presentation and interesting stories.  For a Free Earth Science presentation at your school or organization call the Stockton Lapidary Club at 209.946.0113   

For many years Richard and Mary Calderon have been the “Rock Hound” Event volunteer manager for the San Joaquin County Science Olympiad A2 division, 3rd to 6th grade, for the San Joaquin County Office of Education.
