Water Quality Unit Timeline

The following is a suggested timeline that was developed after the unit was implemented for the first time and reflects what we feel would be a good pace for the students to learn at. We have added a week onto the original timeline as we felt that going over the water quality tests in more detail, as well as allowing the students more time to work on their projects would be beneficial. This timeline is by no means prescriptive, and the order of all water quality tests can be easily interchanged. Assuming that the class meets 5 days a week for 45-50 minutes, 5 weeks are allocated to the whole unit, with the final 2 weeks devoted to the Final Project.
