This is a human demography lab where tombstones are analyzed to compare growth curves between those who died in the first half of the 20th Century with the last half of the 20th Century. This can be done as a field trip (get permission first!) or in the school using the tombstone pictures. The lab can be done either in the auditorium with the pictures taped to the chairs or in the classroom. This is a good lab for A.P. Environmental Science.
The only difference between this version and the free version is that this version has the 200+ pictures.
