w Explain what a contour is.

w
Draw simple topographic maps that illustrate various landforms:
Review from before New this week
� steep slope
� gentle slope
� plain
� hill
� closed basin
� ridge
� valley
� stream valley

w Interpret the contours on a topographic map showing the landforms listed above.

w Using a US Geological Survey (USGS) topographic map, do the following:

� Determine the latitude and longitude of the sides of the quadrangle;
� Determine the elevation of a given point on the map;
� Identify streams;
� Find the elevation of a stream at a given point on the map.

w Draw simple topographic maps that illustrate various landforms: hill, ridge, closed basin, valley

w Use a topographic map to determine what direction a stream flows.

w Use a physiographic map of the Chicago area to investigate landforms.

w Explain the difference between surficial sediments and bedrock

w Explain what dolomite (also called dolostone) is, tell why it might be a commonly-used geologic resource in the Chicago area, and give examples of how it can be used.

w Draw simple topographic maps that illustrate various landforms: hill, ridge, closed basin, valley

w Use a topographic map to determine what direction a stream flows.

w
Explain the difference between surficial sediments and bedrock

w
Use a physiographic map of the Chicago area to investigate landforms.

w Use a geologic map of the Chicago area to do the following:
 
           * list rocks and sediments that occur in the area;
           *
find an area where bedrock is exposed
           * find the same area on each of several different maps, accounting for the differences in scale, and compare what each maps shows.

w List other geologic resources that can be found in the Chicago area, and tell how they can be used.

w List geologic resources not found in the Chicago area, and explain the considerations in making them available to Chicagoans.

w List some of the reasons why a quarry might be situated in a particular area, and why it might *not* be appropriate in some other areas.

w Show that you can use topographic and geologic maps to find good locations for quarries, considering all the factors we discussed.

w Use a physiographic map of the Chicago area to investigate landforms.

w Using maps of different scales and purposes, "zoom in" and "zoom out" to correlate the maps and compile information for a particular area.

w
Determine what topographic quadrangles are adjacent to any given quad.

w Use the topographic map index found on the Willman map.

w Use the Cook County topographic map index on the ISGS website.

w Use a topographic map to create topographic profiles of a landform on the south side that we'll refer to as "the worm".

w
Use critical thinking to create and evaluate hypotheses for the origin of "the worm".

w Revisit "the worm": show how you can pinpoint it accurately on the Blue Island quadrangle, and re-draw the N-S and E-W profiles across it.

w Describe the "grid drawing" method of creating a picture (see an example here) and explain how we are using it in this class.

w
Use the topographic map index found on the Willman map.

w
Planning Your Future:  Based on the information provided by Dr. David Helfand of the Career Counseling Office, identify the factors that determine what job or career path may be right for you.  List both "Career Awareness" factors and "Self Awareness" factors.

w Using the materials provided in class, understand everything you need to complete Homework #5.

w Continue creating "puzzle pieces" for the Moraine Mosaic.

w
Demonstrate how to use a hand level and stadia rod to measure the slope of the land surface.

w Be ready to participate in our field trip to Gompers Park on Thursday.  The park is on the southwest corner of Foster and Pulaski.  Meet in the east parking lot (off Pulaski) at class time, Thursday, October 30!

w Draw a diagram illustrating the slope-measuring method you used.

w Using the field trip handout, explore and describe the water features in the park. 

w List the members of your Team Project team, and describe the Team Project objectives and requirements.

w Using the Team Project overview document, be ready to complete the first team project assignment (see the Homework page) by the required deadline.
