At the math station, students walk five transects looking for deer droppings. Deer leave droppings about 12 times a day which means there are a lot of them and that they can be used to estimate deer populations in a given area. Students count droppings in each of the five transects and use their numbers to calculate the population in the park. Thank goodness for calculators!

The sixth graders work at Birch Creek State Park on the north side of Lake Somerville. Here they are studying tracks and other animal signs with a Master Naturalist volunteer.

At Birch Creek the 6th graders compared the bug gathering technique for determining pollution levels to chemical testing using probeware.

Part of the 6th grade curriculum deals with watersheds and soils. Here students gather soil samples to test their capacity to hold water.
