1. Do Now: Copy HW from the board Take a clicker Take a POGIL Complete PAGE 1!!!!

2. DIAGRAM 1: Toppling the upright book requires only a slight raising of its CG. Toppling the flat book requires a relatively large raising of its CG. Which book is more stable? WHY? 1.First book 2.Second book 3.same

3. DIAGRAM 2:For the pen to topple when it is on its flat end, it must rotate over one edge. During the rotation, the CG rises slightly and then falls. Is the pen more stable standing up, or flat on the ground? WHY?? 1.Standing up 2.Flat on ground 3.same

4. DIAGRAM 3: Which is more stable? 1.A 2.B 3.same

5. Today’s Tasks 1.Work Diligently on POGIL (you should complete up to p. 5-6) 2.Work at your own pace and GET THE SUPPORT you need! (ask questions!!!) 3.If you want to go over your test in more depth, see me! I will work with you (Less than 25 Physics classes until finals…!!!)
