archimedes' principle

An introduction to density that explains how it determines whether objects float or sink and discusses how people use floating and sinking in their lives.

Presents an introduction to the concepts of sinking and floating, in simple text with illustrations, explaining how density and shape impact whether an object will sink or float.

Uses simple experiments and activities to explore concepts such as density, upthrust, and water displacement and to explain why objects float or sink.
