Water displacement is a method used to measure the volume of an object by observing the amount of water it displaces when submerged. By recording the initial water level in a container and then noting the new water level after the object is added, the difference in levels indicates the object's vol...
Water Displacement Lab
Name: ________________________________________ Period: ______________
Purpose: Today you will learn to determine
the volume of irregular-shaped objects. We
will use a procedure called water Hypothesis (If…then..because...:
displacement.
Materials:
• graduated cylinder
• bottle or beaker of water
• collection of irregular shaped objects
• Pencil or Pen
• Calculator
1. (MEASURE) Using water bottles or pitcher, fill graduated cylinder to 50mL (get as close as
possible). Record this as your initial volume in the table below.
2. (DROP) Carefully drop object into the graduated cylinder. Wait for water the settle.
3. (MEASURE) Read the new volume reading. Record this as your final volume.
4. (SUBTRACT) Calculate the difference of the two volume readings. [Remember: (Final) - (First)].
This number will be the volume of the object. Record this reading on the table below.
5. Repeat steps #2 through #5 for all objects in bin.
6. Answer Lab Conclusion questions on next page.
