Water Quality Testing

Activity Overview

This water quality project has been designed around a monthly sampling routine for the extent of the project scope. One of the sampling days involved three different classes, each class sampling a different station. This project measured several biotic / abiotic factors to determine the interrelatedness of these factors. At each station, the following abiotic factors were measured utilizing Vernier probes in conjunction with TI- Nspire Calculator; water temperature, salinity, dissolved oxygen
