SUGGESTED PROCEDURE:
As the students receive the materials packet, encourage group exploration and quick
comparisons. Simple discussion questions
should be used to have the students notice the use of colors, symbols, and labeling
techniques. Use sections 1, 2, and 3 for
this.
Introduction to color, symbols, and scale: Ask the following discussion questions and have
the students identify and locate topographic symbols.
Using the topographic symbols chart and the topographic map:
Blue colored features represent?
Green colored features represent?
Black colored features represent?
Brown colored features represent?
Purple colored features represent?
Using the topographic symbols chart:
Identify the symbol for marsh.
Identify symbol for a power line.
Identify symbol for a school.
Identify symbol for a dual highway with median.
On the Bisbee 1:24,000 topographic map
Locate a mine tunnel.
Locate a mine shaft or prospect.
Locate a tailing pond.
Locate a tailing dump.
Using the 1:24,000 Bisbee topographic map
Find the scale in feet.
Find ?0" on the scale. Why
are there 1,000 feet to the left and 1000 feet to the right of ?0"?
Using the edge of a piece of paper, determine the distance in
feet from the Lincoln School in Bisbee to the Greenway school in Warren.
What is the straight line distance? ________________________________
What is the distance traveling by car? ____________________________
Section 1:
Given the table below, first find the object listed on the
topographic map and then locate the identified site on the aerial photograph.
Object | Location |
Lavender Pit | Northeast quadrant of map |
The towns of Bisbee, Lowell, |
|
Saginaw, Galena, Bakersville, |
|
Warren, South Bisbee, Tintown |
Section 2: On
the 1996 Aerial Photograph:
1.
Mine Tailings
2.
Settling Ponds
3.
Forested Area
1.
Are there any features are seen in 1996 that were not
there in 1978?
2.
Can you find any features that were there in 1978 but not
there in 1996?
ASSESSMENT:
1.
The instructor
will circulate throughout the room questioning each group to establish student mastery of
the materials and to troubleshoot and direct student
attention to features and
objects.
2.
If the materials
have been laminated, students may label the objects or places in Sections 1- 2 using a
washable or erasable marker.
3.
Student journal entries on the objectives of the activity.
4.
After completing
the search and locate tasks provided in Sections 1- 3, the student or cooperative group
may select other objects or sites to develop peer
quizzes.
EXPLORATIONS MAY INCLUDE:
Packets of local topographic maps and aerial photographs for the
students to identify known and unknown sites.
Student construction of a school topographic map completed to
scale and properly oriented.
