Ask the students to see if they can identify the areas in Palmetto where people of different ethnic groups, i.e. Jews, Greeks, Anglo-Americans, etc. are buried. They should, with a little help, see that there are separate sections for various ethnic groups. The existence of segregation explains the separate Black and White cemeteries. But, why would Jews and Greeks be buried in separate areas from Anglo-Americans in the same cemetery? (Hint: religious differences matter; marketing practices matter. How are cemetery plots sold?) Ask them to see if they can see any differences between gravestones and crypts.
Before the tour ask each cemetery if they can provide a guide and give a talk about the cemetery, its history, how things are done there, visitors, anecdotes suitable for children, etc.
Ask each student to prepare a brief report on what they learned about cemeteries and burial customs. You should have data on 400+ burials. This should be enough to draw demographic graphs for each cemetery showing how long people lived in various periods. [Hint: Be sure NOT to mix data from widely varying time periods.]
