Unit 12 Schedule
2013 -  2014

The following schedule information was prepared at the beginning of the unit.  It is not fixed in stone. It's role is to serve as an organizational tool for students to find both required and helpful resources relevant to daily activities. The schedule is seldom updated as the unit progresses; if we fall behind, then topics or depth of topics will be reduced in order to keep the overall pace required to maximize coverage of the entire curriculum.

 Day 1: Wednesday, February 19 Lesson Plan: Organization - packets, MOP sheets, introduce Unit 12 Discuss Reading Guide: momentum and impulse - def'n, equation, units, vector; impulse-momentum change relationship Twosomes: Packet, pp 1-2, #1-9; do #10-11 together Lab M2 - Balloon Toss; do and post-lab Homework: Read TPC, Momentum, Lesson 1 MOP - Assignment M1 Complete Lab M2 Announcements: The Momentum unit features several problem sets, 10 sublevels of MOP (we will  do 7 of them), and as many as 6 labs. Take charge of your learning and it will be a successful unit. Online Help:

 Day 2: Tuesday, February 25 Lesson Plan: Organization - test comments Warm-up: Simple Computations with I=∆p (pp. 5-6) Demo - Mountain Climbing; followed up with Q#4-5 on p. 4 Lab M3 - Rebounding vs. Sticking; do and post-lab Homework: WebAssign - Momentum Change and Impulse 1 MOP - Assignment M2 Announcements: The Momentum unit features several problem sets, 10 sublevels of MOP (we will do 7 of them), and as many as 6 labs. Take charge of your learning and it will be a successful unit. Online Help:

 Day 3: Thursday, February 27 Lesson Plan: Demo on rebounding; use as a post-lab of Lab M3; do Q#6-10 on page 4 Lab M5 - Action-Reaction - do and post-lab Develop ∆p1 = ∆p2; start p. 7, #1-4; relate to Newton's third law and second law Homework: Read TPC, Momentum, Lesson 2, sections a, b, c, d MOP - Assignment M3 Announcements: Ancient Chinese proverb: "The wise man completes the MOP assignments at a steady pace; the fool hurries the work during the last minute." Have a good weekend. Online Help:

 Day 4: Tuesday, March 4 Lesson Plan: Quick review of ∆p1 = ∆p2; start p. 7, #1-4; relate to Newton's third law; then do questions  #5-11 on pp. 8-9 as a warm-up System momentum analysis: begin with pp. 9-10, Q#16-17 followed by pp. 11-12 Lab M4 - Before and After Lab Homework: WebAssign - Momentum Conservation - Ass't 1 MOP - Assignment M4 Lab Notebooks (Labs 2, 3, 4 and 5 to be graded) Announcements: The fundamentals of the unit have just about been covered. What remains is a whole lot of applications. Lab notebooks will be collected on the next physics day. Online Help:
