Science 8:  After a review of numerous optics topics, we completed the Waves and Optics Practice Test, which is due on Thursday.  Test on Friday.

Chemistry 12:  We took brief notes on Hydrolysis, a process were salts can cause the formation of hydronium and/or hydroxide in water.   We read section 4.13 then completed # 69, 71, 72, and 68.  We finished with a quiz on partial neutralization reactions.  

Chemistry 11: We spoke about the rock cycle - rocks are largely mixtures of ionic compounds and so share the characteristics of ionic substances:  high melting point and brittle.  We took brief notes on Ionic Bonding, then we read pages 170 - 176 and completed Unit 8 # 53-67.  Quality point form has short phrases but no single words or numbers.  We finished by planning how to find the molar concentration of NaCl in saturated salt solution.
