|MadSci Network: Environment & Ecology|
I would suggest the following two textbooks for an upper level ecology course in high school: Smith, R.L. and T. M. Smith 1998., Elements of Ecology 4th edition Benjamon/Cummins ISBN 0-321-01518-5 Molles, Manuel C. 1999. Ecology, Concepts and applications WCB McGraw Hill ISBN 0-07-042716-x A possible lab manual might be Cox, George W. Labnoratory Manul of General Ecology, Wm C. Brown, though it may or not be appropriate depending on the level of your students. The Ecological Society of America maintains a web site that has links to their lab manual which has some nice lab exercises http://esa.sdsc.edu/ed_resources.htm Good luck
