Fri-Day 2
Physics - we discussed the demonstration that showed that, neglecting air resistance, different mass objects fall at the same rate, with the same acceleration, towards the Earth. We reasoned that the greater the mass of an object, the greater its force of gravitational attraction. However, the greater the mass of an object, the greater its INERTIA i.e. the more force required to move it! These opposing factors balance out to make all objects move towards the Earth with the same acceleration.
We completed a lab safety discussion and worksheet. Please have the safety contract signed over the weekend.

AP Chem - we discussed, dissected, and manipulated everything that has to do with the Bunsen burner. After this process, you should never have any problem knowing exactly how to control or correct the flame in any Bunsen burner.
The practice test for next Wednesday will be posted by Sunday afternoon, as will the answer key (update: the answer key is NOW posted). See me at extra help on Tuesday morning at 8-ish, if you have any trouble at all with the test.
