In-class assignment for students NOT attending the field trip

The following assignment is for students who are NOT attending the field trip and should be completed during the class period that you would normally see me.

THEREFORE – IT’S NOT HOMEWORK FOR TOMORROW/TUESDAY. IT’S TO BE DONE IN CLASS!!!!

Students should read the following articles:

http://www.pbs.org/wgbh/pages/frontline/poisonedwaters/themes/endocrine.html http://www.usatoday.com/news/nation/2008-03-10-drugs-tap-water_N.htm

They should go here: http://www.ncsu.edu/sciencejunction/depot/experiments/water/index.html and read about pH, temperature, dissolved oxygen, nitrates/phosphates, and macroinvertebrates.

They should then work in pairs to develop a profile of what they think a healthy water system would be like (temperature, pH, oxygen level, nitrate level and types of macroinvertebrates.) They should also develop a profile of what they think an unhealthy water system would be like.
