Wednes-Day 1
Bio - we discussed common diseases of the excretory system: gout and kidney stones.
We then wrote out an explanation of how the circulatory and excretory systems work together to help maintain homestasis in the body.
We discussed the scientific method with respect to today's profound article regarding the seminal paper on vaccination and autism that was retracted by The Lancet. I posted the article in your notes on Blackboard.
We reviewed for tomorrow's exam; there are a lot of extra help materials on Blackboard. I have posted practice quizzes, animations, and the answers to all of the worksheets handed out in class (including today's).
If you have questions about anything, email me or see me at extra help tomorrow morning in Room 308 @ 8:15.
Let's start the third quarter with a great score- apply your test-taking skills, CAREFULLY identify/underline keywords in the questions, predict/DRAW an answer, and MAKE SURE that your answer DIRECTLY addresses what is asked for. You can use the many colored pens to highlight your tests.
Be sure that you are familiar with the various diagrams of the heart, lungs, kidney, organ systems for this unit.
Remember the lung demonstration that we did with the balloons: as I pulled down on the diaphragm (contraction), the volume of the cavity expanded, decreasing the air pressure inside, so the lungs passively inflated as the higher pressure external air rushed into the balloons! Lungs are NOT muscles, they CANNOT contract, but rather passively get filled with air or get the air squeezed out of them due to the diaphragm contraction and relaxation, respectively.
As always, please review the videos on the scientific method and on graphing properly- these videos are located at the BOTTOM of the Unit 1 Files section on Blackboard.
AP Chem- we finished the mechanism problem and then did a combined mechanism/ rate law from raw data problem.
Tomorrow, we will cover the "time-dependent" rate law equations - the final of the three main parts of this unit.
I had to stress the importance of being busy and attentive at all times in class because we are losing time in this fast paced course. We needed to start the equilibrium unit yesterday. We have to pick up the pace so you have to practice REINFORCING the material from class with repetition and practice problems that are available on Blackboard, always. If you do NOT understand something, you MUST come to extra help or at the very least, ask me a SPECIFIC question via email. I am here every day; if you want a special review session on a particular topic or even to reinforce a given day's lesson, I will DO SO.
