Mars National Aeronautics and Space Agency The Xtreme-o-philes! School of Earth and Space Exploration Arizona State University Mars Education Program
This leads to the question…. Is what we define as extreme here on Earth…… actually “NORMAL” out there?
Explore Option #1: Handouts and PowerPoint Option #2: Common Core focus Reading in Science Craft and Structure #4 Integration of Knowledge and Ideas #7, #8 Writing in Science Text Types and Purposes #1a, 1b, 1c, 1d, 1e Research to Build and Present Knowledge #8, 9 Range of Writing #10
Elaborate Your Extremophile selection was based on a general description of Mars Earth has many unique environments Mars has many unique environments Let’s see if any of Earth’s Extremophiles could find a habitable place on Mars
Elaborate MISCONCEPTION ALERT!! Life has never been found outside of Earth We are looking for potential places of interest that “could” harbor Extremophiles
Symbol Description: Can survive radiation of space Thrives in temperatures below 0°C Can be found in areas with minimal water Can be found in areas that are salty Typically found in neutral pH environments between 5 - 8
Symbol Description: Exposed to the radiation of space Temperatures range from below 0°C to 40°C Very minimal or no water Area lacks salts or was not tested for salt presence Areas was not tested for pH, therefore pH is unknown
Evaluate justify the reasons for their selection including our understanding of life on Mars today; include critical information such as the abiotic materials that can be used to support the biotic environment; give examples of how the organism could potentially exist in that particular landing site specifically including genetic variations; and consider the potential for life not only in the present environment, but in past environments.
Extend Have students select extremophiles that could potentially live on Mars and be producers for other extremophiles, acting in primary succession Use the Marsbound! activity found at http://marsed.asu.edu/lesson-plans-marsbound to have students plan a mission to Mars looking for extremophiles at their proposed landing site using Engineering Practices and the Iterative Design Cycle. http://marsed.asu.edu/lesson-plans-marsbound
