Volume Notes
And a flow chart
Define Volume
• Volume is the amount of
space an object takes up
or…
• Volume is the amount of
material a container can
hold
• Example: this bottle can
hold 1 Liter of H2O
What is the base
unit for finding
Volume?
• -Remember the base unit
for finding volume is Liter
• -The abbreviation for Liter
is an uppercase L
• -The two most common
volume measurements are
mL and L
• -Remember that 1 L is the
same as 1000 mL
Liquids
• To measure volumes
smaller than a liter,
scientist use the milliliter
(mL).
• There are approximately
20 drops of water in 1 mL.
• Remember: there are 1000
mL in a single Liter.
What Tools do we
use to find volume?
•
What if we are finding the
volume of a liquid… what
tool do we use?
• Liquids use a graduated
cylinder
• A graduated cylinder is
usually calibrated in
milliliters.
• Each line on a graduated
cylinder is one milliliter.
What about
rectangular
prisms?
• To get the volume right we
multiply what?
• Length x width x height
• Why do we use cm3?
What is displacement and
how do we use it to find
volume?
• Displacement is the
difference in water level
(volume) due to the
addition of another
material

What tool
would you
use?
Are you finding the volume
of a LIQUID
Directions
for tool:
1.
Pour liquid into
graduated cylinder
2. Get eye level with the
meniscus of the liquid.
3. As accurately as possible
determine where the
bottom of the meniscus
is to find your volume
4. Remember to use the
correct units (ex: 13 mL)
A Graduated Cylinder finds
the volume of liquids.
It measures liquids in mL.

for tool:
1.
Line the item right on the 0 cm
line.
2. Find the two numbers it is in
between (ex: 8 and 9)
3. Count how many lines past
your object is (ex: 3 lines)

1.
Fill graduated cylinder to a
set volume (ex: 200 mL)
2. Gently place item into
graduated cylinder.
3. Read the new volume (ex:
270 mL)
4. Find the difference of the

5. For solid objects don’t
forget to convert from mL
to cm3

1.
Fill a displacement cup with
water right up to the brim,
and place it inside a tray or
other container.
2. Then place your irregular
object in the water, and
watch the water overflow a
graduated cylinder.
3. The volume of water you
collect in the graduated
cylinder will be equal to the
volume of your object.
