SI System - Factor-Label Method (8.27.07)

Welcome to day 6!!!!!!
Objectives:
SWBAT Convert between SI Units
SWBAT Use dimensional analysis method of conversions
Catalyst:
Why would it be important to have
one universal system of measurement
that everyone uses?
Agenda 8/24
 Converting between SI Units
 Using dimensional analysis method of
conversions
 Practice makes perfect!!!!
