buoyant ascent (hydrodynamics)

An introduction to the physical properties of weight and buoyancy, including everyday examples.

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

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

Presents information on floating and sinking in liquids or air, providing instructions for relevant scientific experiments.

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

Illustrates with experiments how objects displace water to stay afloat, why some objects float and others sink, and why the water's ability to sustain weight makes swimming, diving, and other water sports possible.
