Finding Volume Lab
Purpose:
To accurately use a metric graduated cylinder to find volumes of liquids and irregular solids.
To successfully use a metric ruler to find the volume of rectangular solids.
Task #1: Liquid Volume:
Materials:
colored water, test tube stand, 6 test tubes/A-F, graduated cylinder
Procedure:
1. Label 6 different test tubes A, B, C, D, E, & F.
2. Into test tube A add 19mL of red water.
3. Into test tube C add 18 mL of yellow water.
4. Into test tube E add 18 mL of blue water.
5. From test tube C take 4mL and pour the 4mL into test tube D.
6. From test tube E take 7mL and add it to test tube D MIX.
7. From the beaker of blue water measure 4mL and pour it into test tube F.
8. From the beaker of red water measure 7mL and add it to test tube F MIX.
9. From test tube A take 8mL of water and pour into test tube B.
10. From test tube C take 3mL and add it to test tube B MIX.
11. Record the final color of the water found in each test tube in the data table below.
12. Measure & record (in the data table) the final volume of the water found in each test tube.
13. Convert the volume measurements into liters and record in the final column of the data table below.
14. Rinse out all test tubes and place upside down in racks.
15. Do not dump out or mix beakers of colored water.

4.
Pour water into a 50mL or 100mL graduated cylinder. Fill half way full.
Record Volume in mL
Carefully place the irregular solid into the water. Record volume of water plus object
Subtract the volume of the water alone from the volume of the water plus object to get the volume of
irregular solid.
