METRIC BASE UNITSMETER –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)

AREA = LENGTH X WIDTHFFFFFFFF

10 CM

7 CM

LENGTH = 10 CMWIDTH = 7 CM

10 CM X 7 CM = 70 CM2

VOLUME OF A SOLIDVOLUME = LENGTH X WIDTH X HEIGHT

8 CM

6 CM

5 CMLENGTH = 8 CMWIDTH = 6 CMHEIGHT = 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

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

BULB

MASSTHE 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.
