Transcript

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