SciGuides are a collection of thematically aligned lesson plans, simulations, and web-based resources for teachers to use with their students centered on standards-aligned science concepts.
Our conception of "life" on other planets, especially what life on Mars may resemble or has resembled in the past, is based upon the media. Our images have been of "little green Martians." Before we can learn and understand the complexity known as Mars, we must first learn about Earth. Using "Earth-The Making of a Planet" by Roy Gallant and Christopher Schuberth, discovering and exploring Earth will assist us in our journey to Mars. Before searching the wide variety of web sites, we will also review the Astrobiology Goals mentioned in the Astrobiology Roadmap. See web site-http://astrobiology.arc.nasa.gov/roadmap/
With our two explorer rovers, Opportunity and Spirit, both traversing the surface of the red planet, together with the research data and pictures that we have previously received from the Viking and Pathfinder missions, we now speculate that life may exist now or has existed in the past on Mars. Scientists believe that life on Mars was/is life in the form of bacterial-type organisms, many of which are invisible to the naked eye.
Come, join us in a voyage from Antarctica, at the bottom of the world, to Siberia, at the top of the world; from Baja, California to the Bahamas; and from Earth to the Meridiani Planum on Mars. The Internet will connect you and your students, using content and activities, to the study of life on earth and its relevance to the discovery of past and perhaps present life on Mars.
