We measure in order to 1.) DESCRIBE
2.) COMPARE
We measure: (1.) Length (2.) Mass (3.) Volume
In Science we measure using the METRIC SYSTEM.
It is based on the number 10.
LENGTH – The Basic Unit is METERS
MASS – The Basic Unit is GRAMS
VOLUME – The Basic Unit is LITERS
To change the Basic Unit we add a prefix to the base
word.
Kilo = 1000 Deci = 1/10 Centi = 1/100
Example: Kilometer 1,000 meters
ONE METER = 10 decimeters
100 centimeters
1000 millimeters
Milli = 1/1000
VOLUME
Volume is how much space something takes up.
The unit volume is measured in LITERS (L)
or CUBIC CENTIMETERS (cm3)
There are two ways to find volume
Regular Objects
1. To measure a regular object
(regular – it can be measured with a ruler)
LENGTH x WIDTH x HEIGHT
IRREGULAR OBJECTS
2. To measure an irregular shaped object
(Irregular – it can not be measured with a ruler)
Use the WATER DISPLACEMENT METHOD
The instrument used to measure the volume is a
Graduated Cylinder
The Meniscus is the curved (concave) line in the
graduated cylinder at the top of liquid.
