CHICAGO ROCKS!  Geology in the City
ESCI 109, Section 01
Fall 2009

Review for Exam #3 (December 17, 2009)                                                                                            Dr. Sanders

w  Your final homework assignment is due the day of the final exam.
w  Check the homework page for the poster grading rubric; use it as your checklist as you finish working on your poster! 
w  You will be asked to complete the Team Citizenship Evaulation during the exam period.


For the exam, you should be able to do the following:


Topographic Maps

w
  Use contours on a topographic map to find the location of stream valleys.

w
  Determine the direction of flow of a stream using contours on a topographic map.

w
  Sketch what a stream valley would look like on a topographic map. 

w
  Using contours on a topographic map, point out areas of steeper slopes and less steep slopes.


Stream Processes and Gradients


w  (From our field trip) Trace the stream at Gompers Park from beginning to end, describing the changes it undergoes throughout its course.

w  (From our field trip) Explain how a constructed wetlands functions to help resolve some urban water management problems.

w  Define the meaning of the term watershed (drainage basin).

w  Show how to delineate a watershed using a topographic map.

w  Define the term gradient

w  Explain how stream gradient can be measured using topographic maps.

w  Measure the gradient of the following streams using topographic maps.

  4 Fox River 4 East Branch of the DuPage River 4 Sanitary and Ship Canal
  4 Des Plaines River (state line to Lyons) 4 West Branch of the DuPage River 4 North Shore Channel
  4 Upper Salt Creek (above Busse Lake) 4 North Branch of the Chicago River 4 Calumet Sag Channel
  4 Lower Salt Creek (below Busse Lake)    

w  Find the gradient of the three major canals in the Chicago area (North Shore Channel, Cal-Sag Channel, Sanitary and Ship Canal).

w
  Analyze the stream gradients we measured using topographic maps.

w  Measure the gradient of a slope using a hand level, measuring tape, and stadia rod.


Topographic Maps, Stream Processes, and Surficial Geology

w
  Use contours on a topographic map to find the location of stream valleys.

w  Define the meaning of the term watershed (drainage basin).

w  Show how to delineate a watershed using a topographic map.

w  On the big map of the Chicago region at the front of the room, use sticky notes to mark the general location of each of the following streams.  Then explain what they virtually all have in common, and what caused that commonality.

  4 Fox River 4 Sanitary and Ship Canal 4 East Branch of the DuPage River
  4 Des Plaines River 4 North Shore Channel 4 West Branch of the DuPage River
  4  Salt Creek 4 Calumet Sag Channel 4 North Branch of the Chicago River

w  Explain what controls the location of the major streams in the Chicago area.

w  Describe the characteristics of the intermorainal areas in the Chicago area.

Group Project

w  List and describe the characteristics of a productive and contributing team member.

w  Working in the assigned project groups, investigate a given study area.

Team Project Overview

Project Goal:
 Investigate the geology of a specific geologic feature.

Project Requirements 
           
m  See the homework page for more information!
           
m  Work as a team
           
m  Perform library/web, map, and field research
           
m  Communicate your findings to the class via a poster presentation.

Project Deliverables
           
m  Several homework assignments will involve parts of the project.
           
m  Poster Presentation:  Following the project requirements, produce a poster that presents your findings.
           
m  Team Citizenship Evaluation:  At the end of the project, everyone will rate their own and their team members' participation.  Individual grades will reflect the team grade, weighted by the results of the Team Citizenship Evaluation.
