Astrobiology is an integrative science with the theme of searching for the signatures of life in the universe. Investigations about nanobacteria, abiotic versus biotic signatures, comets and meteorites delivering water and hydrocarbons to Earth, and the quest for terrestrial extra solar planets and life will highlight this program. This workshop designed for secondary science teachers will emphasize professional development by including brain research on learning, lectures and activities led by scientists and state-of-the-art lab tours. Teachers will review NASA mission curriculum materials and do other activities aligned with 2061 Benchmarks. The workshop will target returnee teachers to advance their knowledge base and may include some curriculum development. Registration fee is $50. Because of a tuition waiver, 2 University of Hawaii graduate education credits will be offered for the administrative fee of $158. A limited number of teachers from continental US will receive a subsidy of $750 to defray expenses. Accepted Hawaii teachers will be fully subsidized.
