Through indoor instruction and intensive field learning, you will develop familiarity with Silurian and glacial geology, fossils of northeastern Illinois, and using topographic maps to interpret the geologic history of your surroundings. Learn how to excite your class with geology and earn CPDUs with NGSS guidance from the Illinois Science Teachers Association. The workshop is open to all interested adult learners. Teachers register at ilscience.org for CDPUs. Adult learners can register by calling Sagawau.
