We conduct Earth Science Presentations for grade schools and non-profit organizations free of charge. A large collection of various rocks and minerals 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 Richard Calderon of our Education Committee, at 209-601-1497 or 209-482-5632.
For many years Mr. Calderon has been the “Rock Hound” Event volunteer manager for the San Joaquin County Science Olympiad A2 division, 3rd to 6thgrade, for the San Joaquin County Office of Education. Mr. and Mrs. Calderon conduct Olympiad coaching sessions upon request from teachers whose classes participate in the Olympiad.
