Science 8:  We reviewed electrons, protons, and neutrons before we finished Lab 10-3.  All the Analyze and Conclude and Apply problems (in fine sentences) are due tomorrow.  This clip shows the interactions between saline water and fresh water at an estuary.  We will have a Chemistry Practice Test on Tuesday, and a Chemistry Unit Test on Thursday.  In the last minutes we learned briefly about determining the frequency of repetitive motion, such as wave forms.  This site has wave animations, and we determined the frequecy of both the transverse wave and the longitudinal wave.   We also watched Usain's 9.58 s 100m race in Berlin, and found the frequency of his footsteps.

Chemistry 12:  We completed a short review WS on Solubility topics, then read section 3.5 (separation of ions by precipitation) and completed Unit 3 # 26 - 32 and 37-38 (due Tuesday).  Ensure that all the Unit 3 practice problems are complete, because we are close to a Solubilily Unit Test (Tuesday, November 12).  So far we have completed Unit 3 # 1-10, 15, 18, 20a-d, 40-52, 56-66.  Whew! You have learned a lot in the first half of this course.  

Chemistry 11:  Lab 6A was collected today.   After a mini review of writing products and balancing reactions, we read Hebdon Section 6.6 and completed # 68-80 (due Tuesday).  If there was time, preparing Lab 6B is a good thing to do, but this is not due Tuesday.  In the last minutes we wrote a quiz on writing products, balancing, and stoichometry.
