What is the basic unit for measuring
liquids?
The liter
There are 3 larger units and 3 smaller
units, what are there prefixes?
Kilo-, hecto-, deca-, and deci-, centi-, and

Volume- The amount of
space matter takes up.
Graduates – The marked
and unmarked lines on
the graduated cylinder
 Meniscus-The bottom
of the U-shaped curve
of a liquid in a
graduated cylinder
meniscus
When finding the volume, bend down so
the graduated cylinder is at eye level.
Then read the graduate at the bottom of
the curve.
Get down at eye level to read meniscus

To find the volume in a graduated
cylinder you need to know three
important pieces of information:
You must determine (1)how the
scale is increasing with each
graduate, (2)where you should
measure from, (3)and what metric
unit to use for the measurement.
• Scale increases by 10ml
• Measure from the meniscus at eye
level
• Use the metric unit, ml

Never measure from the
top of the meniscus

Measure from here, The
bottom of the meniscus is
the standard point of
measurement.
