  1. Human Impact on Marine Life Pollution in the Ocean

  2. Warm Up • What is pollution? • In what ways do humans pollute the Chesapeake Bay? • In what ways can you stop pollution from getting into the Bay? • How does oil from the roads get into the Bay?

  3. Independent ResearchTake Cornell Notes over the following topics: • Page 541-555 • 22.1-Sewage Pollution • 22.2-Toxic Chemicals

  4. Independent Research: Sewage PollutionUse Cornell Notes to answer the following:

  5. Video: PollutionMake a list of as many different types of pollution that you see during the movie. • Human Impact on Marine Life-Pollution Video

  6. Food Chain BasicsWhy are decomposers (bacteria) important? • Watch the video to make sure you understand the following: • Autotrophs • Heterotrophs • Decomposers

  7. E. Coli • Bacteria cells are usually______________ (prokaryotic/eukaryotic). • Remember from your biology class! • E. Coli are prokaryotic (simple/unicellular) cells. • Prokaryotic Cells are SIMPLE. • They lack membrane bound organelles. • No nucleus • DNA floats around in the cytoplasm. • Cilia (hair like) or Flagella (tails-think sperm) are common in these cells to help them move

  8. Independent Research: DDT & PCBsUse Cornell Notes to answer the following:

  9. DDT and FATTY TISSUE/BLUBBER • Fatty tissue/blubber belongs to the _______________ category of macromolecules (proteins/lipids/carbohydrates/nucleic acids). • Remember from your biology class! • Lipids are made of fatty acids. • Energy is stored in lipids for long periods of time. • For example, marine animals that live in cold waters will store energy in their blubber to survive long cold winters. • Toxins are also stored in fatty tissues. • Fat takes a long time to burn off. This means that toxins in fatty tissues can harm a body for a long time.

  10. Lipids and Higher Level Thinking • Which of the following would be harmed by toxins such as DDT? • A whale. • A lean fish such as Tuna.

  11. Independent Research: MercuryUse Cornell Notes to answer the following:

  12. Biological Magnification and Food Chains • Put the following in order on a food chain • Carnivore • Herbivore • Producer • Consumer Use the picture to explain bio magnification. Fish Eating Human (top carnivore) Shark (carnivore) Tile Fish (omnivore) Zooplankton (herbivore) Phytoplankton (producer/decomposer)

  13. Mercury and the Nervous System • Which of following are part of the nervous system? • Heart and blood vessels • Lungs and nose • Brain and spinal cord • Bones and cartilage • Brain, spinal cord and nerves make up the nervous system. • Remember! The nervous system controls your body’s movements without you even knowing (heart pumping/eyesight/breathing).

  14. Independent Research: Other metals, oil spills and radioactive wastesUse Cornell Notes to answer the following:

  15. Oil Pollution-Oil Eating Bacteria • Oil spill clean up video

  16. Radioactive Wastes • Radioactive Waste video

  17. Additional Text Assignments Follow

  18. Striped Bass in the Hudson River • Read Swimming with the Fishes on page 549. • Answer questions 1-3

  19. Extra Student Work • Section Review 22.1 & 22.2
