Thurs-Day 2
Bio- we focused on the underlying reason for cell division (cytokinesis): the surface area to volume ratio of the cell. As a cell grows, surface area increases at a slower rate than volume which is why the surface area to volume ration decreases and the cell is compelled to either divide or die.
The notes and PowerPoints for this week are on Blackboard.
HW- Outline Text Section 7.1, due Friday.
Bring in your Biochem tests for Friday. We will go over TEST-TAKING skills, which continue to be completely ignored by those of you who did not do well on the test. If you want to improve, you will consistently follow the invaluable test-taking advice that I demonstrate to you.
Reminder: as soon as you reach your desk in class, take out your notebook and either copy what is on the board or be prepared to immediately take notes as soon as attendance is taken.
Chem 7/8- Here is a link to yesterday's Nobel Prize winning chemist!
We began our new unit on Chemical Reactions and Kinetics. We noted where to place REACTANTS (before the arrow) and PRODUCTS (after the arrow). We emphasized balancing chemical equations in order to respect the Law of Conservation of Mass in a chemical reaction. We also learned two ways to represent either an endothermic or an exothermic thermochemical equation/reaction.
The notes and worksheet are on Blackboard.
Heat of Fusion and Phase Change labs are due Friday, Oct. 12 !
We then did a lab in which we identified an exothermic CHEMICAL change/reaction and an endothermic chemical change/reaction.
Chem 9- Here is a link to yesterday's Nobel Prize winning chemist!
