Science 8:  We wrote the 3 characteristics of a system down on our Human Body Systems Placemat after we reviewed the names and functions of a few systems.   We learned the meaning of dilute, concentrated, and diffusion before reading pages 40 - 42.   This animation shows how diffusion works.   In the second half we did a short experiment to answer the question of whether diffusion happens faster in hot water than in cold water.  We wrote the question, a hypothesis, our prediction (based on our procedure), and data and observations.  Nothing is due for next class.

Chemistry 11:  I collected Lab 3A today at the start.  We reviewed naming and writing formulas for ionic compounds. We learned about hydrates for the first time today.  Due Tuesday is Unit 4 # 5 (a-l), 6, and 7.  We prepared lab 2E today.  Our first unit test will be on Friday.  

Chemistry 12:  We reviewed a few topics to start, then we wrote notes on Reaction Mechanisms.  We read section 1.10, 1,11, and 1.12 today.  Due Tuesday is Unit 1 # 54-62.  The work from Friday was not collected (Unit 1 # 46-52) yet.
