Transcript

  • 1. Photosynthesis
    EQ:What resources do plants need to make food?
    How does plants and animals help each other?
    Warmup Review:
    What does an energy pyramid represent? Why does energy run out by the time it gets to a 3rd level or 4th level consumer?
  • 2.
  • 3. Photosynthesis is like Baking
    Make a cake
    Ingredients
    Eggs
    Milk
    Flour
    Oven/Pan
    Heat
    Gives energy
    Cake mix turns to cake.
    Make Sugar(glucose)
    Ingredients
    Carbon Dioxide
    Water
    Plant/Chlorophyll
    Sunlight
    Gives energy
    Ingredients are turned into SUGAR!!(glucose)
  • 4. Photosynthesis
    Photosynthesis is a chemical reaction just like cake!
    What do we need for photosynthesis?
    Ingredients:
    Water
    Carbon Dioxide
    ENERGY!!
    Sunlight
  • 5. Sugar is like a battery
    When an organism needs energy, they can burn sugar.
  • 6. Oxygen
    When a plant makes sugar there is leftovers.
    Very important for us!
    Making sugar leaves extra oxygen which plants breathe out. We breathe in.
  • 7. Oxygen burns
    Why do we need oxygen?
    To BURN Sugar
    We burn sugar for energy.
    Burning sugar makes Carbon Dioxide
  • 8. Carbon Dioxide
    Who needs carbon dioxide?
    Why do plants need carbon dioxide?
    How do animals help plants?
    How do plants help animals?
  • 9. Summary
    Sunlight
    Carbon Dioxide
    Water
    Oxygen
    Sugar
  • 10. Carbon Dioxide-Oxygen Cycle
  • 11.
  • 12. Review
    What two chemicals do plants need to make sugar?
    What do plants need from sunlight to be able to turn chemicals into food?
    What do plants breathe out when they are done with photosynthesis?
    How do animals get the sugar?
    Why do animals need the sugar?
    What do the animals release when they breathe out?
  • 13. Draw a diagram with a plant and an animal. Include the following things.
    Show the plant taking in Carbon Dioxide and water, Sunlight
    Show what the plant releases
    Show what the animal takes in
    Show what the animal releases.
    Show sugar
