a sheet of paper and stand it up on your desk like a tent.
Using the principles of contouring, draw the contour lines that would
appear on it. Then, draw the map that would illustrate those
Flip the paper upside down so it forms a "V". Draw the equal elevation contours and map.
Start with a fresh piece of paper, crease it, and prop one end of it on a book so it forms a tilted tent. Draw the topographic contours and map.
Finally, flip the paper upside down so it forms a "V", tilt it, and draw the contours and map.
a topographic map of the area carved in the sand on
the stream table. When you are done, have
the instructor check your map.
Then, construct a new shape in the sand for another group to map. Make a map of this area too—yours will be the “answer key”.
the topographic quadrangles of Chicago Loop and Palos Park, find a
place that illustrates the following
features. Label and place sticky notes on the map to indicate the
location of each feature.
* a gentle slope
* a steep slope
* a closed depression
* a round hill top
* a ridge (elongated hilltop)
* a lake
* a benchmark
a stream; find two places where contour lines cross the
same stream and put sticky notes on the map to show both places. Tell what direction the stream is flowing.
* a “Gaging Station” along a stream
* a forested or undeveloped area (how can you tell?)
* an urban area (how can you tell?)
