A cemetery provides an ideal location for student investigative research. Cemeteries are easily accessible in all communities and provide a field location for a non-cookbook style of laboratory activity. Students can examine tombstone weathering rates, reinforcing rock identification. Students may collect cemetery demographic data, comparing the longevity and survivorship data with local environmental events and impacts.

This is an activity that was modified from PDE's SAS resource portal.  It offers two mini activities, one student investigation and one teaching demonstration, for exploring the movement of convection currents. This lesson is set up to have students use Claim, Evidence and Reasoning to both predict and analyze the investigations.
