Standard of Inquiry: Direct Observation
1) Gather information from direct observations
· Display data in appropriate format (e.g. graphs, tables, charts, diagrams)
This part of the standard is to be completed in the math curriculum.
I. Compass/Map work
a) Explain basic compass and orienteering techniques
b) Explain the scaling of maps and the use of ratios
· Activity 1): Construct a map of the classroom or cafeteria on lined paper
with the use of a measuring device and compass. Determine
fixed points in the room and appropriately scale down all
elements.
· Activity 2): Take bearings between fixed positions in the room.
c) Explain the use of the compass plotters and triangulation.
· Activity 1): Do plotter readings of the same compass readings in the earlier
activity.
· Activity 2): Triangulate two bearing readings from fixed positions.
II. Map projections of the U.S. and world.
a) Discussion of different map projections.
· Latitude/Longitude
· Universal Transverse Mercator (UTM)
· Cadastral Surveying (Township/Range)
b) Explain U.S.G.S. maps and contour lines.
c) Conversions between projections.
· Activity 1): Convert from Lat/Long decimal degrees to degree/minute/second
and plot on U.S.G.S. maps using scaled template.
· Activity 2): Convert Lat/Long points on map into UTM coordinates using
UTM template.
· Activity 3): Plot Cadastral readings on U.S.G.S. maps and convert to
UTM's.
III. Scent Post Survey data analysis
a) Creating rations from collected data and discuss bar graphs.
· Activity 1): Display collected data in a bar graph
b) Discuss conversions to decimals.
· Activity 1): Convert all data ratios into decimal and percent equivalents.
c) Discuss pie graphs and converting decimals to degrees.
· Activity 1): Convert decimals to degrees and create a pie graph.
