This site is a preview version of the Astrobiology Curriculum, an interdisciplinary year-long course for middle and high school students developed by TERC and NASA. Through a series of investigations based on the search for life on other planets, students explore diverse concepts in chemistry, biology, Earth and space science, and engineering. Topics include the geologic history of planets, the chemical foundations of life, biological diversity, extremophiles, and the use of remote-sensing instrumentation. Students develop research skills through modeling, lab experiments, field observations, and image and data analysis, and are linked to data from NASA's planetary space missions. The site includes links to the overview, course description, sample activities with teacher guide, student guide and worksheets, and other astrobiology links.
