Winding roads...take me home!
Day two started off with a short trek to Yellow Creek. Each of the vans had different areas to take samples in the same watershed (upstream, downstream and a vernal bog/spring.) Our van took samples at the spring. An interesting fact about the spring was how much areas like this prevented flooding because it held so much water.
Our next stop was at the coke furnace in Coketon. They drop the coal in the top of the coke oven. They heat up the coal to take out all of the oxygen and impurities (left with carbon) and the coke went to Pittsbirgh for the steel mills. The purpose of using coke instead of regular coal is because it makes better steel (you want higher carbon content and this is what you are getting.)
After we left Coketon, we went to the falls at the North fork of the Blackwater river. Below is a picture of the falls. We took samples at a pyritic stream which caused the pH to be acidic. We learned that limestone (basic) was dumped in the stream to make the pH closer to neutral. Overall, I thoroughly enjoyed the fieldwork we did today.
Great start to the Blog. Include how you are going to use this with your students, or what types of projects they can do with this. One thing you might want to think about is making sure you picturesndo not have to much back light- it's just hard to see the entire image.
