Tues-Day 2
Physics - we finished Vectors 2 problem 1, using a new scale so that the vectors fit on the graph.
We then did problem 4, though we didn't get to measure the angle of the resultant. I measured the angle and posted that in the notes on Blackboard.
We will finish the graphical method of combining/adding vectors, and then move on to the more accurate mathematical/trig method (remember SOH-CAH-TOA ? good.)
AP Chem - we finished contrasting molecules and ionic compounds, drawing samples of separate molecules (which NEVER bond together) and then drawing samples of ionically bonded (on ALL sides) cations and anions in a salt's lattice.
We went through the logic of the periodic table to show that KNOWING the charge of a given representative metal cation or nonmetal anion is easy to reason, given the "octet rule" and the knowledge of its cause.
We discussed the test a bit, and then did some sample compound naming and drawing problems.
We discussed the setup of our solubility rule, qualitative analysis lab.
