Wednes-Day 1
Bio 3/6- we compared and contrasted: prokaryotic vs. eukaryotic cells and also plant vs. animal cells. We saw videos that showed the various cell organelles and their functions.
We performed a microscopy procedure on human cheek epithelial cells and Elodea plant cells, practicing our staining techniques to better see the nuclei and membranes of the cells.
AP Chem- The Percent Composition of a Hydrate Lab WRITEUP is due on Friday, in class.
We finished the Dalton's Law stoichiometry problem. We then derived each of the gas laws from the ideal gas law by holding certain pairs of variables constant. We also explained what was occurring at the molecular level in terms of collision frequency and kinetic energy/force of collisions. We also showed, graphically, the relationship between each pair of variables.
I expect to see at extra help those of you who are making many errors on the unit exams; you clearly need to prepare more before each exam and you have not done so.
