Tues-Day 1
AP Chem- explained various types of redox reactions and focused on two main oxidizers: dichromate and permanganate; these two oxidizers react in acidified solutions to form Cr 3+ (aq) and Mn 2+ (aq), respectively, and water.
We then did the electrochem lab question from today's part II question set, which is due on Thursday.
I know that most of you have other AP exams so I will work with you on these HW deadlines but you have to let me know what your schedule/situation is.
No HW or any other assignment will be accepted after the actual 2009 AP Chem exam.
Bio 6/7- answers to the practice test given out at the end of class today are now posted on Blackboard. Do the test first and then check your answers.
We discussed the Heterotroph hypothesis that predicts and explains the first organisms on Earth and their evolution into the various early life forms and their impact on the atmosphere and on the evolution of other organisms. There is supporting evidence for this hypothesis but not as much evidence as there is for the Theory of Evolution.
We also discussed and did application questions on phylogenetic trees; then we practiced with dichotomous keys, which are used to classify/organize various organisms based on phenotypic differences and similarities.
We then began the state lab on natural selection of finches based on beak phenotype for a given food source/selecting agent.
Bio 8- answers to the practice test given out at the end of class today are now posted on Blackboard. Do the test first and then check your answers.
