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.
