Earth Science: Identification of surface features and processes
TIME: Teacher: 30 minutes for preparation of material packets
Class time:
one 50 minute class
MATERIALS:
Student: 2000 Aerial Photograph, Portland, Oregon
1:24,000 scale Topographic Quadrangle
Magnifying glass
Topographic symbols chart
String
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 1:24,000 scale Topographic Quadrangle
Locate a jetty/breakwater.
Locate a benchmark.
Locate a cemetery.
Using the 1:24,000 scale Topographic Quadrangle
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 corner of Jefferson and Broadway in downtown Portland to the southeast corner of the shopping center across the river.
What is the straight line distance? ________________________________
Using a piece of sting, determine the distance in feet from the corner of Jefferson and Broadway in downtown Portland to the southeast corner of the shopping center across the river.
What is the distance by car following the city streets.__________________
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
Shopping center Southeast quadrant of map
Albina Yard Center of map
Alberta Park Northeast quadrant of map
Railway under construction Southwest quadrant of map
Section 2: On the 2000 Aerial Photograph:
a. Locate some forested uplands.
b. Locate an area of light industry.
c. How many ships are docked along the Willamette River?
Section 3: On the 2000 Aerial Photograph:
a. How many bridges cross the Willamette River on the 2000 aerial photographic and how many bridges are on the topographic map?
b. What is the large X pattern feature in the southeast quadrant of the map and in the aerial photographic?
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.
