Human Impact on Marine Life Pollution in the Ocean

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?

Independent Research Take Cornell Notes over the following topics: Page – 22.1-Sewage Pollution – 22.2-Toxic Chemicals

Independent Research: Sewage Pollution Use Cornell Notes to answer the following: 22.1-Sewage Pollution What is sewage? What are pathogens? What harm can they cause? What are fecal coliform bacteria? Are they harmful? How is there prescience in water an indicator of harmful sewage pollution? What waters have high bacteria counts? What is raw sewage? What is E Coli? What type of cell is E Coli? What is sewage treatment? How are other bacteria used at treatment plants? What is sludge? What is done with sludge now? What has happened to the coliform levels in New York City waters? (Use graph)

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

Food Chain Basics Why are decomposers (bacteria) important? Watch the video to make sure you understand the following:video – Autotrophs – Heterotrophs – Decomposers

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

Independent Research: DDT & PCBs Use Cornell Notes to answer the following: 22.2-Toxic Chemicals Who is Rachel Carson? What are toxic chemicals? What is DDT? How was it used? How did it effect Calirfornia brown pelican How did the birds ingest DDT? When was DDT banned? How has this effected the bird populations? Is DDT banned worldwide? What are PCBs? What are they used for? What effect do PCBs have? What is biological magnification? How have Striped Bass been affected by PCBs?

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.

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.

What is Mercury? What is it used for? What effect does Mercury have? How does mercury get into humans? Explain the findings in Japan with mercury levels. Explain how mercury effects the nervous system What is the Clean Water Act and when was it passed? Independent Research: Mercury Use Cornell Notes to answer the following:

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)

Mercury and the Nervous System Which of following are part of the nervous system? A.Heart and blood vessels B.Lungs and nose C.Brain and spinal cord D.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).

What other heavy metals affect marine life and humans? Name 3 big oil spills involving crude oil ships What is nonpoint source pollution? How can bacteria help with oil spills? What are radioactive reactions used for (page 554)? Before 1972, how was radioactive waste handled? How does radioactive waste like strontium-90 affect humans? What is thermal pollution? How does thermal pollution effect marine life? Independent Research: Other metals, oil spills and radioactive wastes Use Cornell Notes to answer the following:

Oil Pollution-Oil Eating Bacteria Oil spill clean up videovideo

Radioactive Wastes Radioactive Waste videovideo
