Changing the Density of an Object: Changing Shape

Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float. The density of the clay used in this activity does not change, but the volume of the object made from the clay increases. This increase in volume decreases the overall density of the object, making it float. [Activity is publicly available through a web crawler capture on Archive.org.
