Wednes-Day 1
AP Chem-SPRING BREAK ASSIGNMENT: was given out in class and is also posted on Blackboard. This assignment should be completed in THREE, TIMED sessions over your extensive vacation. By the time you do the third exam, the questions should be more familiar and easier to do, if you used your notes, etc. for review/research in doing/reviewing the first two exams.
The assignment is due in class on the Monday of your return from break.
Significant point deductions for late or incomplete assignments. Your 4th quarter grade is almost completely determined by this assignment, the electrochem exam, the nuclear exam, and the final exam.
Also, before and after school that Monday, you may take up to three descriptive chem quizzes (10 minutes each) in order to replace a previous descriptive chem grade.
For those doing the KARMA project (which should be anyone who does not have an UN-CURVED, UN-WEIGHTED, "A" average- why would you NOT take advantage of this opportunity to correct what you didn't know, especially when you are not under a time limit and also when you can improve your final quarter average? Your answer to that question is very telling about you as a student.) EVERY STUDENT (20, so far) who has completed this project has achieved a 5 on the AP Chemistry exam and they have told me that this project had a lot to do with making them acquire the knowledge and confidence to achieve such success.
KARMA guidelines:
The project is worth up to 200 points, depending on the number of questions corrected; it CANNOT hurt your average, though you will not be given credit for the oxymoronic "INCORRECT corrections".
On each test, correctly write the answer, in detail, to whatever question part that you previously erred on (though you may also re-write the whole question, if doing so helps you).
If you have sig. fig. errors throughout your test, just write the RULES for sig figs once and do ONE of the corrections for sig figs on that test.
If you have lost an exam, email me and I'll send you a copy, though you will have to do the whole exam.
We took the Thermodynamics unit exam. Things look okay so far except for those who used delta G standard in order to predict changes in K as temperature changes. There is NO such formula because delta G standard CHANGES with temperature and some were keeping its value constant in the equation that relates delta G standard to K. In class (as seen in the notes) we ALWAYS used Le Chatelier and ONLY considered whether a reaction was endothermic or exothermic in order to predict the influence of increasing temperature on the K of a given reaction. Also, I showed you quantitatively that the Van't Hoff formula can also be used to predict such changes.
We have one main unit left: Electrochemistry/Redox. This unit is MUCH more comprehensive and quantitative in AP Chem than it is in Regents Chem so you may want to skim that chapter. We will cover Nuclear Physics in one day also to be ready for the 3 0r 4 nuclear questions on the AP Chem exam.
Bio - I'll be posting your 3rd quarter lab grades sometime next week. Any missing labs or test MUST be completed on the Monday, before or after school, of your return from vacation. Third-quarter grades will be entered that evening.
introduced the MOST important and central unifying concept of the entirety of Biology:
The Modern Synthetic Theory of Evolution. This Theory takes the successfully supported tenets of Darwin's Theory and combines them with successfully tested tenets of Modern Genetics. This far-reaching and powerful theory allows us to make many predictions and explanations about changes within species and speciation, the development of new species; the theory also predicts and explain the extinction of species.
