Metric Mania Volume

1. Lesson 3:
Volume
T. Trimpe 2008 http://sciencespot.net/

2. English vs. Metric Units
Which is larger?
A. 1 liter or 1 gallon
B. 1 liter or 1 quart
C. 1 milliliter or 1 fluid ounce
1 gallon = 3.79 liters
It would take approximately 3 ¾ 1-
liter bottles to equal a gallon.
1 fl oz = 29.573 ml
1 12-oz can of soda
would equal
approximately 355 ml.
1 quart = 0.946 liters

3. Metric Units
Volume is the amount of space an object takes
up.
The base unit of volume in the metric system in
the liter and is represented by L or l.
Standard: 1 liter is equal to one cubic
decimeter
Metric Units
1 liter (L) = 1000 milliliters (mL)
1 milliliter (mL) = 1 cm
3
(or cc) = 1 gram*
Which is larger?
A. 1 liter or 1500 milliliters
B. 200 milliliters or 1.2 liters
C. 12 cm
3
or 1.2 milliliters*

We will be using graduated cylinders to
find the volume of liquids and other objects.
Read the measurement based on the bottom of the
meniscus or curve. When using a real cylinder, make
sure you are eye-level with the level of the water.
What is the volume of water in the cylinder? _____mL
What causes the meniscus?
A concave meniscus occurs when the molecules of the liquid
attract those of the container. The glass attracts the water on
the sides.

5. Reading the
Graduated Cylinder
•Liquids in glass and
some plastic
containers curve at the
edges
•Changing the diameter
of the cylinder will
change the shape of
the curve
•This curve is called the•MENISCUS

6. •Your eye should be level with
the top of the liquid
Reading the
Graduated Cylinder
You should
read to the
bottom of the
MENISCUS
