Fresh Water Study

The Freshwater Study is conducted at a typical freshwater lake some kilometers from the coastline. Once again students work in groups of 5-6 and are supplied with the necessary equipment to conduct the study. Items include collecting trays, steel dip nets, thermometers, salinometers, identification guides and measuring tapes. Students observe and record all the different species of flora and fauna at their study site, with the help of biologists who are familiar with the life forms. They also measure abiotic variables, such as surface water temperature and salinity, water visibility, substrate type, current flow and pH of the water. Students draw a typical food chain using the variety of animals and plants identified at their study sites. The living specimens are returned to their habitats once identified. After the field notes are completed students are free to cool off in the freshwater lake.
