  • Sorting Out Life

    1. 1. Bell Ringer <ul><li>Quickly and quietly… </li></ul><ul><li>Get out a piece of paper </li></ul><ul><li>List the following words & try to explain what they mean. </li></ul><ul><li>Individual </li></ul><ul><li>Population </li></ul><ul><li>Ecosystem </li></ul><ul><li>Community </li></ul><ul><li>Abiotic </li></ul>
    2. 2. Sorting Out Life FOSS Investigation 2 Part 1
    3. 3. Organize It!! <ul><li>Scientists need a reference system </li></ul><ul><li>Organize all levels of life to make sense of its structure </li></ul><ul><li>For example – the Earth is a series of “nested, interacting spheres” </li></ul><ul><li>Lithosphere </li></ul><ul><ul><ul><li>Rocky, mineral, solid layer extending to the solid area of the Earth’s mantle </li></ul></ul></ul>http://www2.cet.edu/ete/hil912/intro/spheres.html
    4. 4. Earth’s Layers Continued <ul><li>Atmosphere </li></ul><ul><ul><ul><li>Thin layer of gases surrounding the Earth that extends 600 km above the surface </li></ul></ul></ul><ul><li>Hydrosphere </li></ul><ul><ul><ul><li>The Earth’s water component </li></ul></ul></ul><ul><ul><ul><ul><li>Liquid, gas, and solids including lakes, rivers, glaciers, clouds, fog, and rain </li></ul></ul></ul></ul>http://www2.cet.edu/ete/hil912/intro/spheres.html
    5. 5. Earth’s Layers continued <ul><li>Biosphere </li></ul><ul><ul><li>All the living organisms contained on & around the Earth </li></ul></ul><ul><ul><li>This sphere interacts with the lithosphere and can be found in the atmosphere </li></ul></ul><ul><li>Ecosphere </li></ul><ul><ul><li>All spheres listed above are included in the ecosphere </li></ul></ul><ul><ul><ul><li>A portion of the ecosphere is found in each of the previous spheres </li></ul></ul></ul><ul><ul><li>Any area of the planet that contains a living thing in it </li></ul></ul>http://www2.cet.edu/ete/hil912/intro/spheres.html
    6. 6. VISUAL MODEL OF THE EARTH’S SPHERES <ul><li>http://www.classzone.com/books/earth_science/terc/content/visualizations/es0102/es0102page01.cfm?chapter_no=visualization </li></ul>
    7. 7. Ecosphere <ul><li>Millions of life forms in the ecosphere </li></ul><ul><li>Specific vocabulary to identify life within it </li></ul><ul><li>Many of the life forms called species </li></ul><ul><li>An individual is the smallest unit of a species </li></ul><ul><li>A population is more than one type of organism or species </li></ul><ul><li>These populations are part of a community. </li></ul>
    8. 8. Vocabulary Terms <ul><ul><li>Organism = any living thing </li></ul></ul><ul><ul><li>Species = a particular group of organisms </li></ul></ul><ul><ul><li>Individual = one single organism or species </li></ul></ul><ul><ul><li>Population = a group of individuals or more than one individual (species or organism) </li></ul></ul><ul><ul><li>Community = interacting populations in a particular area </li></ul></ul>
    9. 9. Three Views <ul><li>Smallest view </li></ul><ul><ul><li>Individual </li></ul></ul><ul><li>Medium view </li></ul><ul><ul><li>Population </li></ul></ul><ul><li>Larger view </li></ul><ul><ul><li>Community </li></ul></ul><ul><li>All deal with living part of the ecosphere </li></ul><ul><ul><li>Biotic factors and effects </li></ul></ul><ul><li>The ecosphere contains biotic and abiotic factors and effects! </li></ul><ul><li>All living and nonliving things within it. </li></ul>
    10. 10. Ecosystem <ul><li>Focus for our studies in this class. </li></ul><ul><li>Piece of ecology containing biotic & abiotic factors </li></ul><ul><li>Example </li></ul><ul><ul><li>Sea </li></ul></ul><ul><ul><li>Aquatic organisms </li></ul></ul><ul><ul><ul><li>Fish, kelp, algae, plankton, sharks </li></ul></ul></ul><ul><ul><li>Rocks, dirt, salt found under & in sea water </li></ul></ul>
    11. 11. Other Vocabulary Terms <ul><li>Ecosystem = an area where organisms interact with nonliving factors (system) </li></ul><ul><li>Biotic = living organisms and their products </li></ul><ul><li>Abiotic = anything that is nonliving </li></ul>
    12. 12. Ecosystem Card Sort <ul><li>In groups….Organize deck of ecosystem cards into groups listed on the two papers </li></ul><ul><ul><li>Individual, population, Undecided, Community, Ecosystem, & Abiotic </li></ul></ul><ul><li>Make sure that you have a reason why you place it in the category </li></ul><ul><li>Use the Ecosystem Card Sort WS to log your info </li></ul>
