Transcript of World Geography Chapter 4 Lessons 1 and 2

Welcome to The
Great Lakes!
World Geography
Chapter 4 The Great Lakes

Mr. Poepperling
Lesson 1 and 2: Geographic Setting and the Lakes: Past, Present, and Pollution
Standards and Objectives
Academic Standards
- SS.912 G3.3, SS.912 G5.1, G5.2, G5.3, G5.4, and G5.5

1. Explain how the Great Lakes are an ecosystem

2. Read an article and analyze the ways in which
the Great Lakes have become polluted

3. Present two ways by which humans can reduce pollution in the Great Lakes
Ticket out of the Door
How can people best use
and protect Earth's
freshwater ecosystems?
- In your notebooks, answer the following questions...
1. Explain where the Great Lakes are located
2. Describe three uses people have for the Great Lakes
3. Predict two ways in which the Great Lakes
could have become polluted

-Write at least 6 complete sentences!!
Geographic Setting and Geoterms

Five lakes- Superior, Michigan, Huron, Erie, and Ontario- make up the Great Lakes
- All but Lake Michigan are shared by the U.S.
and Canada: they make up a vast ecosystem
- Largest group of freshwater lakes ON EARTH
Geoterms to know:
- Ecosystem
- Food Chain
- Food Web
- Freshwater
- Watershed
- Water pollution
A Vast and Varied Ecosystem
- Living things in the Great Lakes are connected to each other through a
food web
- Every ecosystem has its own food web, which is made of many
food chains
Insects eat plants
Insects eaten by fish
Tiny fish eaten by larger fish
Eagles eat larger fish
- If one part of the food web is harmed,
it affects all living things in the ecosystem
- If a fish is poisoned by pollution,
the eagle that eats the fish will have no food
A new pollution worry for Lake Michigan:
Tiny Plastic Fibers
by: Chicago Tribune
Read the article on Great Lakes pollution and highlight the text each time you come across a way in which the Great Lakes have been polluted
Task #1
Task #2:

Read the article again and mark any significant information that shows how people can help to protect the Great Lakes by solving the problem presented in the article
A new pollution worry for Lake Michigan: Tiny Plastic Fibers
Task 4:
After highlighting and marking your article, answer the essential question in at least two paragraphs on the sheet provided:

How can people best use and protect Earth's freshwater ecosystems?
Task 3:
Create your own solutions
that will help answer the essential question

Post solutions on post-it notes on the board!
The Great Lakes Today
- During the 1960's and 1970's the Great Lakes pollution
worried many people

- In 1972 Canada and the United States created the Water
Quality Agreement, pledging to clean up and protect the
Great Lakes ecosystem

- Laws put strict limits on toxic chemicals released into the lakes
- New laws gradually worked and helped improve the ecosystem
Today- clean up continues
- The best way to deal with pollution is to prevent it
- People are being educated on ways to prevent pollution
- Preservation is necessary to maintain the Great Lakes ecosystem!
How can people best use and protect Earth's freshwater ecosystems?
Now that you have taken notes, discussed, and created your own questions, answer the essential question:
Lake Erie algae
from pollution
Microfibers found
in the Great Lakes
Task 5:
PEER into your responses with the PEER worksheet, revise, and finalize your response!
