Students study soils, the associated soils food chain and threats to this system during their field experience. Using a detailed data sheet, students work in small groups to analyze soil properties. In addition, students use a variety of techniques to do an inventory of soil macro-invertebrates. A special attempt is made to search out abandoned snail shells as part of an on-going inventory to monitor their populations. Snail numbers are of concern to scientists because of diminishing levels of calcium in soil resulting from acid deposition. All data collected is posted on the internet via an on-line database.
