This is a short, animated, PowerPoint slide show, demonstrating the method used to find the volume of an irregular solid (a swimmer doll) using liquid displacement. The original volume of water in the graduated cylinder is measured, the swimmer races over to the graduated cylinder and jumps into the water, the water level rises, and the new volume of the water is measured. The subtraction of the two numbers is shown, along with the results.Note - It is also part of my bundled packages of lesson
