Measuring Liquid Volume Procedure
Volume: In this lab you will use a graduated cylinder to measure and transfer
precise amounts of liquids. Remember, in order to accurately measure liquids in a
graduated cylinder, you should read the level at the bottom of the meniscus, the
curve surface of the liquid.
Material:
 Masking tape
 Markers 6 large test tubes
 Test-tube rack
 10 mL graduated cylinder
 3 beakers filled with colored liquids
 Small funnel
Procedure:
1. Using the masking tape and marker, label the test tubes A, B, C, D,
E, and F. Place them in the test-tube rack. Be careful not to confuse
the test tubes.
2. Using the 10 mL graduated cylinder and the funnel, pour 14 mL of
the red liquid into test tube A. (To do this, first pour 10 mL of the
liquid into the test tube and then add 4 mL of liquid.)
3. Rinse the graduated cylinder and funnel between uses.
4. Measure 13 mL of the yellow liquid, and pour it into test tube C.
Then measure 13 mL of the blue liquid, and pour it into test tube E.
5. Transfer 4mL of liquid from test tube C into test tube D. Transfer 7
mL of liquid from test tube E into test tube D.
6. Measure 4 mL of blue liquid from the beaker, and pour it into test
tube F. Measure 7 mL of red liquid from beaker, and pour it into
test tube F.
7. Transfer 8 mL of liquid from test tube A into test tube B. Transfer
3 mL of liquid from test tube C into test tube B.
Collect Data:
1. In the data table, record the color of the liquid in each test tube.
2. Use the graduated cylinder to measure the volume of liquid in each
test tube, and record the volumes in your data table.
Did all of the groups report the same colors? Explain why the colors were the
same or different.
Why should you not fill the graduated cylinder to the very top?
