Welcome to day 6!!!!!!
Objectives:SWBAT Convert between SI UnitsSWBAT 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!!!!
5pts extra credit if everything in by Friday!

SI System/Dimensional Analysis Method
SI System & Dimensional Analysis Method
Key point #1: The SI System is a way of measuring in science
SI System & Dimensional Analysis Method
SI System – Le System International – a universal measuring system.
SI System & Dimensional Analysis Method
Key point #2: SI prefixes can be used with ANY of the SI units
SI System & Dimensional Analysis Method
Basic Units:Length – meter (m)Mass – kilogram (kg)Volume – liter (L)Density – (kg/L) or (kg/m3)
SI System & Dimensional Analysis Method
Prefixes:King kilo 1000Henry hecto 100Died deka 10By base unit 1
