Week 2.5!

• Mon 9/11:  Make 2 mesocosms from pond water.  Make your first observations.  Look for variety of critters, clarity of water, condition of the plants, and anything else you notice.  Also, look for differences between the 2 mesocosms.  We will be making observations for the next 2-3 weeks and then you will summarize your observations and surmise what is going on within these two sealed ecosystems.  Check off DBQ's and go over them.  Notes on Energy Pyramids and the Carbon Cycle.  At your table, make an illustrated carbon cycle that includes 6 main carbon sinks and the labeled transformations between these sinks.  Please read 4.3 in your text.
• Wed 9/13:  Finish Carbon Cycle Diagrams and make mesocosm observations.  Finish notes on the Carbon Cycle and talk about Greenhouse Gases and the Greenhouse Effect.  Work on DBQ's in 4.3 and 4.4 (p. 222, 227, 234, 236, and 237).  Finally watch Jane Poynter video!  Read 4.4 for homework.
• Fri 9/15:  Evidence for Climate Change.  Uncertainty.  The precautionary principle.  More work on DBQ's.  Check off when complete.  Observe mesocosms.
