** Introduction  **       ======

=
On October 21, 2008 Ms. Chang’s Tuesday and Thursday second period class did stream sampling labs on Swannanoa Creek in the Mill Creek Watershed, and the Catawba River in the Catawba watershed. We tested chemical, physical, and biological attributes of these two streams. ======

 <span style="font-size: 140%; font-family: 'Comic Sans MS',cursive"><span style="font-family: Georgia,serif">We did these labs to determine if water from these two streams is safe for Humans and Animals to drink and use. We compared whether water upstream or downstream after running through town would be safe to drink. Our hypothesis is that the water upstream is safer to drink. ======

Travel to stream(s) <span style="font-family: Georgia,serif"><span style="font-family: Georgia,serif"> <span style="font-family: Georgia,serif">2. In your field notebook, make note of the weather, time, location, and and the date. <span style="font-family: Georgia,serif"><span style="font-family: Georgia,serif"> <span style="font-family: Georgia,serif">3. Start to do the kits. Meaning to test the water for chlorine, phosphate, nitrate, DO, pH, turbidity, and make sure to do the temperature difference from upstream and downstream. <span style="font-family: Georgia,serif"><span style="font-family: Georgia,serif"> <span style="font-family: Georgia,serif">4. Once you get all of the results from the test, you would want to get out the kick net. <span style="font-family: Georgia,serif"><span style="font-family: Georgia,serif"> <span style="font-family: Georgia,serif"> 5. Once you got the kick net out and have rocks on the bottom of it, you want to get 2 people to start kicking around at the bottom of the stream to get any living organisms out. <span style="font-family: Georgia,serif"><span style="font-family: Georgia,serif"> <span style="font-family: Georgia,serif">6. After that you would want to pull up the net and get any moving objects off of the net and put them in ice trays to be looked closely at. <span style="font-family: Georgia,serif"><span style="font-family: Georgia,serif"> <span style="font-family: Georgia,serif">7. Record all of the ogranisms you just found, record in your field notebook. <span style="font-family: Georgia,serif"><span style="font-family: Georgia,serif"> <span style="font-family: Georgia,serif">8. After you finish all of that, you could go downstream farther and do the same test again but this time you don't have to use the kick net if you don't want to do that. <span style="font-family: Georgia,serif"><span style="font-family: Georgia,serif"> <span style="font-family: Georgia,serif">9. Make sure you recorded everything in the right places and then there is your stream sampling project.

<span style="font-family: Georgia,serif">[Discuss what your results mean. State the ideal ranges and whether or not your chemical and physical data for both the Swannanoa Creek and the Catawba River fall into these ranges. If not, mention possible problems and the possible sources for these chemicals.] [State whether the benthic macroinvertebrates you found are sensitive, somewhat sensitive, or tolerant of pollution.] [Make a judgement about the water quality at both sites based on your chemical, physical, and biological data.] ====== <span style="font-family: Georgia,serif"><span style="font-family: Georgia,serif">[Next, compare the Swannanoa Creek to the Catawba River. Write out the comparison in words and also make two bar charts, one for chemical and one for biological. You will need to make the bar chart in Excel, save it as a picture, and then upload the picture onto this website.] [Finally, accept/reject your hypothesis.]
