METRIC PREFIXES KILO- 1000 HECTA – 100 DECA - 10 DECI -.1 ONE TENTH CENTI -.01 ONE HUNDREDTH MILLI -.001 ONE THOUSANDTH

METRIC BASE UNITS METER –BASE UNIT FOR LENGTH LITER – BASE UNIT FOR VOLUME CELSIUS – BASE UNIT FOR TEMPERATURE KILOGRAM – BASE UNIT FOR MASS

METER (m) 1 METER (m) = 100 CENTIMETERS (cm) 1 METER (m) = 1000 MILLIMETERS(mm) 1 CENTIMETER (cm) = 10 MILLIMETERS (mm) 1 KILOMETER (km) = 1000 METERS (m) Left Image: http://webapps.lsa.umich.edu/physics/demolab/controls/imagedemosm.aspx?picid=1167Right

AREA = LENGTH X WIDTH FFFF FFFF 10 CM 7 CM LENGTH = 10 CM WIDTH = 7 CM 10 CM X 7 CM = 70 CM 2

VOLUME OF A SOLID VOLUME = LENGTH X WIDTH X HEIGHT 8 CM 6 CM 5 CM LENGTH = 8 CM WIDTH = 6 CM HEIGHT = 5 CM 8 CM X 6 CM X 5 CM = 240 CM 3

VOLUME IS THE AMOUNT OF SPACE AN OBJECT TAKES UP

LITER (L) BASE UNIT FOR MEASURING LIQUID VOLUME 1 LITER (L) = 1000 MILLILITERS (ML)

MENISCUS THE BOTTOM OF THE CURVE WHICH IS USED TO MEASURE VOLUME IN A GRADUATED CYLINDER Left Image: http:// morrisonlabs.com/meniscus.htm Right Image: http://www.tea.state.tx.us/student.assessment/resources/online/2006/grade8/science/images/20graphicaa.gif

CELSIUS THE METRIC BASE UNIT FOR MEASURING TEMPERATURE IS DEGREES CELSIUS AT 0 C DEGREES CELSIUS WATER FREEZES o AT 100 C DEGREES CELSIUS WATER BOILS o

LIVED FROM 1701 -1744. FROM SWEDEN HE WANTED A 100 DEGREE DIFFERENCE BETWEEN FREEZING AND BOILING WATER. Image from http://en.wikipedia.org/wiki/Anders_Celsius

THERMOMETER AS THE LIQUID WARMS UP, IT TAKES UP MORE SPACE IN THE BULB

MASS THE AMOUNT OF MATTER IN AN OBJECT KILOGRAM (kg) IS THE BASE UNIT OF MASS 1 KILOGRAM (kg) = 1000 GRAMS (g) 1 GRAM (g) = 1000 MILLIGRAMS (mg)

TRIPLE BEAM BALANCE AFTER THE OBJECT IS PLACED ON THE SCALE, THE THREE WEIGHTS ARE MOVED UNTIL THE LINES ON THE BEAM AND SIDE LINE UP

DETERMINE THE WEIGHT AFTER THE SCALE IS BALANCED, THE WEIGHTS ON THE THREE BEAMS ARE ADDED.
