El Nino
Here is some excellent information on El Nino. Click on the image below.
I decided to do a quick recap of our discussions about El Nino (actually this includes today and tomorrow). This might help with your notes.
Ocean circulation and how it changes during El Nino.
Factors that influence currents: winds, land masses, Coriolis effect
Normal non-El Nino [...]
Ocean Studies
We took a very different route towards learning this time. We started with a simple “I Wonder” question “I wonder what causes ocean circulation?”. No introduction from the teacher, no movies, no textbooks, no experiments, not even the internet, just students discussing their ideas.
Then we combined ideas from all the classes, asked a few questions [...]

Chapter Challenge Re-visited
Let’s take a look at what I would have considered as good accurate discussions (answers) in your Chapter Challenge. Good answers could come directly from classroom work without the need to do further research. The textbook (remember you can always checkout a textbook from the media center) and classroom notes are all you needed.
First you [...]
