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.
Introduces the physical properties of objects that sink or float and offers examples of them in everyday life, along with simple experiments to try at home.
Mythbusters Adam Savage and Jamie Hyneman investigate urban legends, including if a child be lifted off the ground by helium balloons and if ping pong balls can be used to raise a sunken ship.
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.
Photographs and text guide young children through a simple science experiment to determine what everyday objects will sink or float in a bowl of water.
