  • Launch
    • Trying as hard as you can not to use your notes, draw the oxygen cycle from yesterday.
    • What are some things in your daily life that carbon might be in?
    • What’s a carbon-based life form mean?
  • Tomorrow’s Exit Slip
    • Will cover:
      • Energy/Chemistry
      • Law of Conservation of Mass
      • Oxygen Cycle
      • Carbon Cycle
  • Carbon Cycle
  • What do these three things have in common?
  • Carbon
  • Carbon
    • One of the most important elements
    • Carbon can form many different molecules.
    • Carbon serves as the main building block for organisms.
    • Carbon is readily found on Earth.
  • Where does Carbon come from?
  • Carbon Dioxide in the Air
        • CO 2 is taken out of the air by plants through photosynthesis.
        • Animals can’t go through photosynthesis so they get their carbon atoms from food they eat.
        • BOTH plants and animals release CO 2 into the air through respiration
        • Decaying plants, animals, and waste after millions of years will be changed into fossil fuels
        • Fossil fuels can be burned by automobiles, releasing carbon back into the atmosphere
  •  
  • Carbon dioxide in the atmosphere Burning of fossil fuels in cars and factories release carbon dioxide Photosynthesis removes carbon dioxide from the air. Cellular respiration releases carbon dioxide into the air Decaying organisms changing into fossil fuels.
