When you step into a full bathtub, you learn a lot about displacement of water. As your body sinks into the tub, the water moves out of the way. But water is also pushing up on you as you enter into it. Why Do Ships Float? reveals the science behind buoyancy and why objects float, even if they are large cruise or military vessels. Colorful photographs and illustrations will enthrall young readers on this voyage through science.
