Jobs (2000-2001): 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. Soil Testing crew: A few groups of kids will conduct tests on the soil to determine how much nitrogen and potassium it has as well as its pH level. Water kit crew: A few groups of kids will conduct water quality tests such as dissolved oxygen, pH, hardness, carbon dioxide, and silica by direct titrations. Water probes crew: Some kids will be using the Palm IIIc with the Vernier probes to conduct dissolved oxygen, pH, temperature, turbidity, and flow rate tests. D. O. kit: An extra dissolved oxygen kit was purchased to make sure all other dissolved oxygen readings are accurate. Fecal Coliform Bacteria: A group of kids in each class will test the water to see if there are any fecal coliform bacteria present. New Tests in 2003-2004!: Because we keep getting good results on every test AND the Benthic Macroinvertebrate sampling shows that our creek is polluted, we have decided to run more tests to find out what exactly is causing the pollution. We have enough money from the Learn and Serve America grant that we were able to purchase the following new tests: E-coli, sulfides, ammonia, iron, lead, copper, chlorine and pesticides. We'll see if any of these come up high.
