Watershed
map and contour activity
In the following pages are the pieces to build
a simplified version of a contour map to the Housatonic Watershed. It consists of a large map of the Housatonic
River Watershed and two separate pages that are contours of the area. You can
make one for your class, or students can make their own. This depends on the ability of your students
and the time you have available, as it involves substantial cutting. When it is complete, students will have a
three dimensional model that represents the watershed.
To construct the map, begin with a copy of
the larger page as the base. You may
want to glue it to a piece of construction paper for a backing. The two smaller pages consist of sections
that are numbered 1-4. These are
individual sections of the larger map, and should be layered on the appropriate
places. These pages can be copied on
card stock to be sturdier. Students can
begin by looking at the watershed map for any landmarks they know and coloring
the bodies of water blue. The dotted
lines indicate where another piece should be layered on top. Students can cut out the contours from the
smaller pages and try to arrange them on the appropriate dotted lines of the
map. When they have matched them all,
insert pieces of clay between each one to raise the elevation and create the
three dimensional effect.
When the map is complete,
