High School Reflects on Their Creek Day Special thanks to Northwestern High School students from Mrs. Bucsek’s class who contributed essays about an all-day educational experience at French Creek in Saegertown recently. Excerpts of various essays follow: On Thursday, November 7th, the Northwestern Senior High School Biology II, Environmental Science, and Consumer Science students went on a field trip to further their knowledge of streams and the riparian zone…. The in-depth (in-depth literally, because I unexpectedly fell in the stream) analysis of the water quality also showed how healthy the stream was…The great amount of information obtained from this field trip made it very worthwhile and beneficial. - Kenny Fourspring Our Biology II class recently traveled to Saegertown, Pennsylvania, to study French Creek. While we were there we did numerous water tests so that we could get a better overview of the creek health. We also studied some of the living organisms in the stream, which also helped us to determine the quality of the French Creek. Our class learned about the effects that the land around the creek, called the riparian zone, could have on a certain area. The experience that our class had was very educational and everyone seemed to have an enjoyable time being taught. - Valerie Keller WATER CHEMISTRY STATION The chemical parameters of the water are also important in determining stream health...These [chemical] factors are closely related and greatly depend on each other, which makes it important to test all of them to determine how and if chemical parameters may change. The students discovered that the water is very resistant to pollution, and a healthy environment for aquatic life. - Kortney Saxton RIPARIAN ZONE /RCE STATION On arriving at our observation point, one of the first things that observers would have noticed is the great riparian zone that surrounded the stream. The riparian zone works as a buffer between the stream and the land that surrounds it. Not only does it supply an area for plant life that requires plenty of water, it also works to keep pollutants from flowing into the creek. Like a sponge, it soaks up the pollutants and lessens their flow into the stream or eliminates them totally. Streams that have lost or that only have small riparian zones do not have as much of a buffer and are more easily polluted by runoff from a leach bed or acid rain. This was not the case for French Creek because it had a firm riparian zone. - Robert L. Denham
PHYSICAL MEASURE/ SUBSTRATE TOPOGRAPHIC MAP STATION AQUATIC LIFE STATION CONCLUSION On our trip to French Creek we learned many new things. I learned the importance of a creek and it’s surroundings. In researching we were taught various ways that a creek benefits our environment. We had an enjoyable time, and hope that we contributed greatly to the studies being done by others... - Valerie Keller

What do the select few Cambridge Springs High School seniors do to pass the hours in Mr. Porter’s Advanced Biology class? They are hard at work, preparing and testing French Creek; specifically three testing sites: the Downtown Bridge of Cambridge Springs, Venango Bridge, and Miller Station Bridge. Mr. Porter has rigorous expectations of duties that must be reported by the groups that travel weekly to one of the alternating creek sites. These duties are namely collecting the physical data and chemical data as well. We then analyze and present our material to be critically judged by the head judge master, Mr. Porter. Our reports from our creek visits include both conclusive chemical and physical information. Our lab tests include the typical eight Creek Connections parameters plus ferrous iron. Other field tests analyzed by Mr. Porter’s senior scientists include: flow rate and stage, and temperature. We are keen to inspect clues marking the passage of animal activity that influence the creek environment. What animals have trespassed here? What impact have they made? The physical data that we have heretofore collected are: inventories of riparian zones and the study of land use effects existing in both the watershed upstream from the sampling site and surrounding the site. We scope the waterway channel characteristics including the average height and width of the stream channel. We then determine if the stream is straight/meandering/braided and if it contains riffles, runs, pools, or dams. Other questions satisfied are those referring to the waterway substrate (bottom). Finally, we study the biological characteristics - what aquatic vegetation is present in the water, how many fish and mussels are seen, and what kind of habitats they live in. If you aren’t yet exhausted by all of this fieldwork we performed get ready for more science! Currently the class is involved in the major project requirement posted for us by our instructor: assessing water toxicity by way of lettuce seed germination. We planted the seeds in petri dishes and observed! After five days, the root lengths of the seeds were measured. We compared those roots of the samples to the roots of the salt solution (which shows the most toxic water can be) and pure water. Sample results which were closest to the pure water results corresponded withmore clean water and the result averages that were farthest from it were more toxic. Other than class work like the Lettuce Seed Bioassay major project, we dabble in biology outside of the Advanced Biology classroom. This work Mr. Porter entitles as our mini projects. The teacher must approve the projects before work can begin on it. Some of the projects done are: how fish react to various environments, paper/plastic recycling, and separate smaller creek tests; much like the ones done in class. We would conclude that the select seniors of Advance Biology class do not exactly waste away the hours at school, or anywhere else, which is evident in our progress of major and minor projects, creek work and class experiments and their subsequent deadlines. We passionately delve into many aspects of Creek awareness, and with this article, connect Cambridge Springs High School to you.
