Ch-Ch-Ch-Changes… in the Environment

Yes its true Mr. Bowie (RIP), the only constant in life is change. The same goes for our environment. Forests didn’t just magically appear, and the great swamps that covered much of the midwest at one point didn’t either. Change occurred in slow and dramatic fashion. Today we’ll be learning about three different types of changes that occur in environments and, good news, this is the last section of our Ecology unit. Those changes are known as:

  • Primary Succession
  • Secondary Succession
  • Eutrophication

Below is a brief (less than 5 minutes) overview of these changes. What I’d like you to do is to 1. take the notes and 2. take a sheet of paper (preferably the one you picked up when you came in), turn it landscape (so that it is wider than it is tall) draw the images shown in the presentation when instructed. When you’re finished there are some review question to cover as well.

Here is a great example of Secondary Succession:

As a reminder, tomorrow in class our lab will require the use of open flames. So please no loose clothing and be prepared to tie your hair back.
