Mortality Curves

Lab Summary

Use a GPS position sensor to analyze data, obtained from a cemetery, for historical survivorship trends, including determining the life spans of people in the area and how these have changed over time.

**Requires My World GIS License.

Theory

Cemeteries in long-established communities can give meaningful information regarding the life spans of people in the area and how these have changed over time. In this lab, students:

  • Collect data as a team using a standardized protocol.
  • Analyze data for historical survivorship trends.
  • Find out how survivorship has changed in their community over the years.
  • Differentiate between a survivorship curve and a mortality curve.

Method

Students gain experience in geospatial analysis by conducting the following activities:

  • Taking a "snapshot" of local life-span data using a standardized protocol to examine and record information from headstones in a cemetery.
  • Importing this data into My World GIS™, and analyzing it for historical survivorship trends.
  • Comparing survivorship and mortality curves.

Sensors / Equipment Used:

PASPORT GPS Position Sensor

(PS-2175)

Collects GPS data simultaneously with other sensor measurements, automatically syncing the data to your latitude, longitude, altitude, and velocity. For use with PASPORT Interfaces.

Materials Used:

Blank data tables - Several
Map of the cemetery 

The Associated Bundle:

College Environmental Science Sensor Bundle

(PS-2930A)

Contains the probeware needed to perform all 26 experiments in the College Environmental Science instructor guide.

Interface Required

This experiment may require software and an interface for data collection.
