Take note from this presentation: Hair and Fiber Notes

Notes should include:

Phases of growth
Hair structure
Medullary Index
How to determine body area
Human or animal
Fiber:  Natural or synthetic



Then, search for another good source of information on evidence for hair and fiber. Include some new information. write down the website address.

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.

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.
