Chem Review & Notes

My name is Mark Rosengarten. Many of you may know me as that crazy chemistry teacher who has all those great videos on YouTube.  Here are my chem review packets.

El Nino

GG 140 Yale University Open Course: THE ATMOSPHERE, THE OCEAN, AND ENVIRONMENTAL CHANGE 

Lecture 23 - El Niño

Overview

The El Niño/Southern Oscillation (ENSO) phenomenon is the primary mode of variability in the equatorial Pacific Ocean. It is composed of two extreme states, El Niño and La Niña. The oscillation between these states can be seen in measurements of sea surface temperature (SST), sea level pressure, thermocline depth, and easterly trade wind strength. Changes in SST and pressure lead to shifting of convective activity across the equatorial Pacific. Changes in the strength of the easterly trade winds lead to changes in the depth of the thermocline, which affect coastal upwelling offshore of South America. If upwelling is reduced, primary productivity is reduced. The effect of ENSO on convection and coastal upwelling makes it an important factor for both agriculture and fishing industries.

AP Environmental Science 2/7

We completed the mechanical weathering lab, which is due Friday, 2/14.

For homework students should look up information about mining.  The main subcategories are practices, environmental impact and solutions/remediation.  Find some information that you are interested in and be prepared to report to the class what you have found.

I have scheduled the computer lab for a project from Mrs. Hazzard and we will do a lab on chemical erosion.  We will also continue on the current notes topic.

This is a link to an article I found on plastics in the environment.

And here is a link to the video of me doing that flame demonstration in a previous school, that I told you about.  And part 2.

In the computer lab we will go to http://appvoices.org/end-mountaintop-removal/ and complete the worksheet for a quiz grade.
