1. Pass out materials to students
2. Using overhead, help students locate their school and circle it. Record elevation on map back.
3.Discuss contour lines - significance, distances apart, uses.
4.Use blue pencil to lightly shade in the largest stream and its tributaries. List names of all these on back of map.
5.Use red pencil to lightly shade all hilltops that are closest around local area.
6.Connect these hilltops to outline watershed
7.Indicate direction of stream flow using arrows.
8.Trace the watershed onto tracing paper, cut out a 2in X 2in square. Measure it and determine the area it encloses in square feet to the maps scale.
9.Calculate the total area of the watershed. Record on back of map
10.Using the string , ruler, and map scale, determine the length in feet of each stream and record.
11.Record elevations at headwaters and where tributaries begin. |
