Energy and Momentum  If you need to retest the "Forces" test go to the PreAP notes section for a packet that you must complete prior to retesting.  EXTRA CREDIT ASSIGNMENT NOW IN THE NOTES SECTION. WOW! Stupid ice!  OK  Here's the deal. 1) Test is still Friday. You have enough information on the HWs and Worksheets (all are posted with keys). And if that's not enough incentive already, we will put a curve on this next test SO STUDY HARD! If you do well on the test you can end up above 100! 2) Buoyancy Extra Credit Quiz has been moved to next 6th weeks, so you can concentrate on Friday's test. Those of you that have already studied will just need to brush up on it. 3) All or Nothing Quizzes and Forces Retests must be done by this Thursday. 4) I will be at Chan's Mongolian Grill (Shopping center at NW corner of Hwy 26 and Prescinct Line) at 1:30 pm Tuesday, Dec 10, for questions and study. 5) Spread the word to ALL PreAP students.
