Fingerprints of Life? Extremophiles: It’s Just Right
All web seminar participants use online tools that allow them to mark-up presenter's slides or share desktop applications in addition to engaging in chat with others online and answering poll questions

During this program, educators learned how to introduce students in grades 5-8 to the exciting world of astrobiology. Seminar participants received strategies for guiding students in exploring why NASA scientists conduct research on extremophiles living on Earth as they search for clues in astromaterials and map Earth-like features on other planets. Teachers received information on the It’s Just Right activity, an inquiry-based lesson where students conduct an experiment to determine a range of tolerance for temperature extremes in samples of bakers' yeast.


This web seminar is part of a series of electronic professional development experiences sponsored by the NASA Explorer Schools (NES) project. NES is NASA's classroom-based gateway for middle school (grades 4-8) and high school (grades 9-12) classrooms providing authentic learning experiences inspired by NASA's unique missions. NES provides free teaching and learning resources that promote student engagement in science, technology, engineering, and mathematics and opportunities for teachers and students to participate in NASA's mission of research and discovery through inquiry-based experiences directly related to the work of NASA scientists and engineers.
