Groups test each section of the river for their assigned abiotic factor and collect data. Each group is assigned one section of the river. This data is recorded. Once a month during remaining portion of Semester One. Same groups will continue to collect and compile abiotic and biotic data.
Baseline data is compiled.
Students graph the compiled data so that relationships can be seen between the numbers of organisms and abiotic factors. The class formulates hypotheses to account for any relationships observed. Once a month for remainder of year. Groups will continue to collect and compile abiotic and biotic data. Three days at end of year.
