In class on Tuesday we spent most of the period discussing the evidence (the things we see happening) that shows the earth is warming. The first piece of evidence we have are record global temperatures. NASA concluded 2009 to be the second warmest hear on record. With average global temperatures continuing to increase each year, [...]
James, thought this might at least give you a laugh, if not some inspiration:
While we did not get to this Friday, we will on Monday. Thought you may want to view before then if you had time: Succession View more presentations from Derrick Willard. *NOTE: I added two new links with stepped diagrams showing good examples and explanations of how primary (after glacier retreats) and secondary (bog to [...]
Trying something new. I don’t like to use much Power Point, but have seen slideshare used as a way to share presentations. Here is today’s presentation: Keystone and Foundation Species View more documents from Derrick Willard. What do you think of Slideshare? No more needing to mail a Power Point to a professor if you [...]
*Note: This is a guest post by A. Gresset in 8th period! On Friday, September 25, we set off to Davidson to learn about Experimental Design outside of the lab. First, Dr. Stanback, an Avian Behavior Scientist explained several of his experiments. In particular, he studies the survival and preferences of different species of birds. [...]
This 18-minute video was made by me a few years ago. While it is a bit grainy, it covers the major field research techniques I try to show students at Davidson each year. It’s mandatory viewing if you did not go, and a good review if you did: *Note: The Internet filter at school will [...]
In APES class the past few days we have been discussing the biotic portion of ecosystems. Today, we shifted gears and began to talk about the abiotic, or nonliving, parts of an ecosystem and agreed that the components are sun, soil, water, and air. What we primarily focused on today was the creation of soil. [...]
Today in APES we learned about the base unit of Ecology, Ecosystems. We started class trying to define what an ecosystem is, and ended up with a definition like this: an Ecosystem is the community of organisms in an area and their interactions, as well as their interactions with the non-living environment. In order to [...]
