It was the second class of year 10 pupils to explore tombstones in recent weeks, and the cemetery provided an ideal learning environment, social sciences head Chris Homer said.
Pupils were asked to research a section of graves, noting the cause of death and the age of people when they died," Mr Homer said.
"One of the patterns the students will pick up is how infant mortality rates have changed. Many of them have commented how young these people were when they died.
The cemetery visit requires pupils to draw on knowledge from several subjects, including social sciences, mathematics and geography.
"It [the cemetery] is a great historical resource for us, and they have really enjoyed getting out of the classroom and coming here," he said.
Jamie Tocher (15) had never visited the cemetery before the school trip.
He said the visit was "better than being crammed up in a classroom".
