Mapping activity
Materials required
- printouts of Mt Lemmon map (1 per two students, see below)
- File:AZ Mount Lemmon 312494 1996 24000 geo.pdf
- File:AZ Mount Bigelow 312482 1996 24000 geo.pdf
- whiteboard,
- dry erase marker
- compass (1 per 2 students)
- field notebooks + pencils (1 per student)
- cardboard and scissors
- meter tapes (1 per 6 students)
Outcomes: students should be able to
- understand major parts of a map
- interpret contour lines and how they reflect changes in slope and drainage
- use a compass to orient and navigate
Hand out maps; in pairs, have students identify the following parts of a map:
- Title/Location
- Compass Rose
- Scale Bar
- Contour Lines
- Colors
- Key/Legend
Group questions: why is it important for a map to have these elements? What else could a map have on it that would be useful?
Cardboard demo of contour maps
- Stack different cardboard cutouts to show the different topologies they represent
- Point out lines on the Mt Lemmon map
Questions: which areas are steepest? Least steep? Where would you find a wash/stream? How high up is site X/Y/Z? Which sites are south facing slopes?
Contour map olympics
- Divide group into teams
- Use whiteboard to draw different contour maps (e.g. single hill, slope, double hill, forking river, etc.) in secret
- show to students and award points for fastest correct interpretation by a group.
Compass instruction
- Give students compasses in pairs. Introduce magnetic north, 'red fred in the shed', how to hold compass.
- Challenges: walking a bearing with closed eyes (other student looks for branches. Compare with landmark navigation.
- Choose two landmarks and demonstrate triangulation. Make up other sightings (e.g. one peak 30°, another peak 30°W, where are we) and test students (in teams) ability to determine their position.
- Scavenger hunt: each team hides an object (pinecone? hat?) and writes directions to it, pirate-map style, using the compass and # of meters on the tape. Switch instructions between groups and try to find the object.
