Marine PollutionNarrated by your classmates

Essential Question:What benefits do you derive from the oceans? How does your behavior (in Chicago) affect the oceans? Give 5 specific examples. ** Leave enough space to answer this essential question at the start of your notes… OR write it down at the beginning make a note in the left column that you will respond in the “summary section” of your CN. **

Objective: SWBAT assess impacts from Marine Pollution.

Ms. B

Describe the term GYRE.http://strangesounds.org/wp-content/uploads/2014/08/Great-Pacific-Garbage-Patch.png

Ms. B starts & hands-off to Group 1 I review continents vs. countries, major oceans, & intro to marine pollution

Plastic debris endangers marine lifeMost ocean pollution is non-point source (from inland

sources too), as the Clean Water Act significantly reduced discharge of point source pollution.Identify types of “trash” or pollutants & how they got into the

oceanTrace the pathway from Chicago to an ocean

Plastic degrades very slowly (500 – 1000 yrs) in salt water and sunlight. As it breaks apart, the pollutant becomes even more harmful as organisms mistake it for food.List two other ways trash will leave the ocean surfaceDescribe three other ways plastics are a detriment to the

ocean and its inhabitantsDiscuss measure(s) to combat this problem (think

legislation)

Group 1

Oil Pollution (from spills of all sizes)

Bioaccumulation & biomagnificationExcess nutrients

Source from __________. Identify it as a point source or non-point source
