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.
