Science 9:  We reviewed some Ecology topics from before the holiday then we started learning about the Carbon Cycle.  This video has a clear description of most of the Carbon cycle.  We read pages 326 to 329.  We wrote brief notes on the effects of increasing carbon dioxide in the air.  These brief notes are due next class.

Science 8:  After a short review we did Lab 5-2 in our textbook.  If you were away, this task could be done at home.  All the questions, written in fine sentences, are due next class.
