Workshop with Dr. Sabina Thomas

Santa Barbara City College campus

Have you been curious about rocks? Do you realize that rocks can tell a story? How does one distinguish one rock from another, and what is the difference between rocks and minerals? Sabina Thomas, PhD, and a faculty member at local community colleges, will conduct an Introduction to Rocks class at Santa Barbara City College’s earth science labs. You will be learning about the different rock families, conduct some simple but helpful tests to identify rocks and minerals, and find out why geologists think that rocks are interesting—they really DO tell a story! The workshop may include a short walk to the La Playa stadium and Maxwell Overlook to briefly explore the local geology. No hammer, hard hats or hiking boots required.
