Astrobiology is an integrative science with the theme of searching for the signatures of life in the universe. Investigations are done comparing the geology of rocks and minerals on our Earth with other planets, the astronomy of small solar bodies such as comets and meteorites delivering water and hydrocarbons to our world, and the quest for extra solar planets orbiting other stars being terrestrial. This workshop designed for secondary science teachers will emphasize professional development with the use of learning cycles for concept development, lectures and activities led by scientists and state-of-the-art lab tours. Teachers will review and do activities from NSF field-tested curricular materials Voyages Through Time by SETI and others aligned with 2061 Benchmarks. Registration fee is $50. Because of a tuition waiver, 2 University of Hawaii graduate education credits will be offered for only an administrative fee of $100. A limited number of teachers from continental US will receive a subsidy of $500 for room and board to defray expenses. Accepted Hawaii teachers will be fully subsidized.
