PDS AP Environmental Science 5th Period 2010-11

This last chapter, we really started to get an idea of how biogeochemical cycles work and can “malfunction.” Here are a few interesting current events on the topic if you want to learn more: Nitrogen Cycle: Whales Help Fertilize Ocean With Floating Dung http://www.npr.org/templates/story/story.php?storyId=130437080 Phosphorus Cycle: Manure, Fertilizer Part Of Chesapeake’s Problem http://www.npr.org/templates/story/story.php?storyId=121565792 Carbon Cycle: [...]

Today we started off class by doing a whiteboarding activity. In this activity we got into groups of 3 and were instructed to determine the main reservoirs of nitrogen, its unique characteristics, and the human impacts on the nitrogen cycle. After each group was finished, we brought the whiteboards into the classroom and as a [...]

Today we talked about the phosphorus cycle. Phosphorus, we learned, is very important because it is a main component in things such as phospholipids, DNA, RNA, ATP, and ADP. By looking at the diagram in our book and study guide, we noticed the main reservoir for phosphorus is sedimentary rock, which is part of the [...]
