Chemistry 12:  We used the Table of Reductions to determine if several proposed reactions were spontaneous or not.  After reading section 5.3 we completed U5 # 7-14, which is due on Monday.  Remaining time was spent completing Lab 21D - the questions and follow-up questions will be due Tuesday.  

Science 10:  We began by reviewing the structure of DNA and how proteins are made by ribosomes in the nucleus.  Everyone was given a gene sequence, then we transcribed the DNA sequence into an mRNA sequence, then translated the protein by using the Codon chart and writing the order of the amino acids.  We caused a few mutations - one that caused a slight change, and another that caused a catastrophic change.  We worked on two genetics review practice quizzes and answer keys were provided for checking your work.  This clip shows how populations change through time.  Spend some time reviewing for your favorite final exam.

Science 8:  We practiced locating an epicenter on a map again, to get really good at it, then we started to write a business letter, but this is not due Monday.
