Simple text and experiments illustrate why objects sink and float.

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

Uses simple experiments and activities to demonstrate the properties of water and such principles as floating.

Presents simple activities and experiments that demonstrate buoyancy by observing why some things sink and others float in water.

Simple activities introduce the qualities of things that float in water, the difference between floating and swimming, and how balloons and airships stay up in the air.
