Film crew: Film the entire process, documentary style. Film in class labs as well. Take still digital photos of the entire process. Edit the footage to create a news show documenting the study. Two students in each of my classes will take on this job.

Macroinvertebrate Sampling group: Two to three students in each class will work with the Benthic Index of Biological Integrity by collecting samples of bugs that will be sent to a lab. We will get to keep one sample to study and classify the bugs ourselves. On the Hood Canal field trips, this group will collect samples of bugs and count them themselves to generate the index of biological integrity.

Water kit crew: Two groups of kids from each class will conduct water quality tests such as dissolved oxygen and pH (2 to 3 students from each class), Nitrates and Phosphates (2 to 3 students from each class) by direct titrations.

Water probes crew: Some kids will be using the Palm IIIc handheld computer or the TI-73 calculator with Vernier probes to conduct dissolved oxygen and pH (2 students from each class), temperature and flow rate (2 students from each class), and turbidity and conductivity (2 students from each class). I have not decided how to take relative humidity and air pressure tests because we ran out of students!

Fecal Coliform Bacteria: Some students will test the water for the presence of fecal coliform bacteria (2 to 3 students from each class).
