Metric System  Metric System: a standard system of measurement used by scientist worldwide  Called System International (SI)  Based on units 10s

Base Units  Mass Measures the amount of matter in an object Units: Grams (g) Instrument used: Balance  Length Measures distance Units: Meters (m) Instrument used: Ruler, meter stick  Volume space an object takes up Measures the amount of space an object takes up Units: Liter (L) – for liquids; Cubic Centimeter (cm 3 ) – for irregular objects Instrument used: Graduated cylinder or Beaker

Rulers a b ￬

How long is the paper clip?

How long is the nail?

How long is the pencil?

Graduated Cylinders  Let’s take a look  Practice 1 Practice 1 http://www.superteacherworksheets.com/measurement /graduated-cylinders-mixed-easy_WMNTW.pdf

Let’s make sure you get it!  Interactive Practice Interactive Practice http://www.wisc-online.com/objects/viewobject.aspx?id=gch302

Thermometers

What is the scale? What is the Temperature?

Triple Beam Balance  Check it out!  Practice Practice  Your Turn! http://www.ohaus.com/input/tutorials/tbb/TBBread.html

Metric Conversions

Mnemonic for Prefixes  Kangaroos – Kilo  Hop – Hecto  Down – Deca  Bumpy – Base  Driveways – Deci  Crushing – Centi  Marshmallows – Milli

Decimals  If decimal is shown, move the decimal from that place Ex. 4.56 (start after the 4)  If the decimal is not shown, it is located behind the last number Ex. 32 (start after the 2)

Let’s Practice  15.32 cm to ________________ m  32,000 mg to ________________ hg  7.05893 kL to _______________mL

Independent Practice Ask Questions if you are confused!!!
