Finding Volume: The Water Displacement Method

We have formulas for finding the volume of geometric shapes, but what if the shape is irregular? Lesson describes how to find volume through water displacement. After a demonstration, scholars practice in small groups. Then analysis questions lead them to connect the information to a larger purpose. Lesson is the second in a series of six.
