We have been involved in Science Fairs in the Tri-Valley and beyond.
We had an educational booth at the Science Fair that was sponsored by the Pleasanton and Dublin Schools and held at the Alameda County Fair Grounds. This was one huge science fair which took up all three of the largest building at the fair grounds. This was a great event but there wasn't enough money to keep it going.
For several years we had in educational table at the Castro Valley Science Fair that was held at Castro Valley High School.
Every year for at least the past ten years the Lithophiles have participated in the Livermore School's Science Odyssey.
