USING A GRADUATED CYLINDER
2
A GRADUATED CYLINDER is a tool that is mostly
used to measure the volume (amount) of a liquid.
3
Graduated Cylinders measure liquids using the
metric unit of milliliters (mL)
1mL

• 1mL is a VERY TINY amount of liquid. It is just
  a few drops!

4
1,000 mL 1liter (L)
5
All graduated cylinders are marked with lines.

• The lines help you measure how much liquid is in
  the cylinder.

6
Look at the graduated cylinders at your table.

• Look at the lines and the numbers.

All graduated cylinders have lines that count by
at least two different numbers. Some count by
20s and 5s. Some count by 10s and 1s.
Some count by 10s and 2s.
What do yours count by?
7
In your notes, use the outlines to DRAW the
graduated cylinders at your table.

• Show the numbers and lines the way they are on
  your cylinders.

8
Now, trade one cylinder with a table in front of
or behind you and draw that cylinder with its
markings.

• Do all graduated cylinders measure using the same
  numbers?

In the blanks below each cylinder you drew,
write the two numbers each one is measuring by.
9
Which cylinder at your table would be best for
measuring out 10mL of water?

• Which one would be best for.
• measuring out 75mL of water?

For measuring 12mL of water?
For measuring 125mL of water?
10
Sometimes the liquid in a cylinder will look
U-shaped at the top. When this happens, read the
number at the BOTTOM OF THE CURVE. This is
called the MENISCUS.
How much liquid is in this cylinder?
MENISCUS
11
Try filling each of the cylinders at your table
with different amounts of water.

• Then, draw a picture of what each cylinder looks
  like with that amount of water in it.

Finally, label each of your drawings, telling
how many mL (milliliters) of water is in each
one.
