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; impulsemomentum

Homework:


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.
