Worksheet 3: Map Analysis

Create 2 Sketch maps to answer the questions below.

Sketch Map 1

  1. Tape a piece of tracing paper over the 1931 Map of Durham.
  2. Use your black pencil to trace the outline of the map and the registration marks. (A registration mark is a circle with a cross in it. There are 4 on the page.) Make a scale on the bottom 1 cm = 2 miles. Then label the map: Greenspace vs. Urban Space in Durham, North Carolina in 1931.
  3. Use your green pencil to trace the shade of every piece of Duke Forest. (Duke Forest is depicted in green on the 1931 map)
  4. Use your yellow pencil to shade all urban areas. (Careful! Urban areas on the 1931 map are outlined in black with a city name in the middle.)

Sketch Map 2
Note: The 2006 map must be in color for the students to do this activity.

  1. Tape a piece of tracing paper over the 2006 Map of Durham.
  2. Use your black pencil to trace the outline of the map and the registration marks. Make a scale on the bottom 1 cm = 2 miles. Then label the map: Greenspace vs. Urban Space in Durham, North Carolina in 2006.
  3. Use your green pencil to trace the outline of every piece of Duke Forest. (You will see 2 additional green areas. Just color these green.)
