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 – Le System International – a universal measuring system.


Key point #2: SI prefixes can be used with ANY of the SI units


Basic Units:Length – meter (m)Mass – kilogram (kg)Volume – liter (L)Density – (kg/L) or (kg/m3)


Prefixes:King kilo 1000Henry hecto 100Died deka 10By base unit 1


Prefixes:Drinking deci .1Chocolate centi .01Milk milli .001


The quick way to doing conversions with these units…


km Hm Dam m dm cm mm

Move decimal to right (Add Zeroes)

Move decimal to left (Take off Zeroes)

Note: these prefixes can be used with ANY of the SI units!
