Using a graduated cylinder to measure the volume of an irregular shaped object is called displacement. 1. Fill the graduated cylinder to 50 mL. Take a photo. Be sure the blue numbers show. 2. Slowly drop the rock into the graduated cylinder. Observe the new water level. 3. Take a photo of your rock in the graduated cylinder. Be sure the numbers show. 4.
