Chemistry 12:  Today we took notes on Hydrolysis, read section 4.13, and completed # 69 & 71 in Unit 4.  Be sure to justify your responses with Bronsted-Lowry reaction equations and Ka and Kb calculations.  I collected Lab 20G today too.

Science 9:  After going through pg 29 # 2-12,14 in the old Science Probe 10 text, we viewed Williamson's lake pond water to look for phytoplankton, zooplankton, and invertebrates.  In aquatic environments, phytoplankton are the main producers, and the food chain goes up from there.
