Change the density of water by adding minerals. The presentation discusses density—from the definition to calculations—and applies it to the real world. It briefly mentions specific gravity, and finishes by showing Archimedes'...

What do Pascal's law, Archimedes' Principle, and Bernoulli's Principle have to do with fluid mechanics? The included PowerPoint presentation provides the basic definitions and equations associated with the three. A set of homework...

In 1879, Sir William Crookes discovered the fourth state of matter, plasma. The presentation covers states of matter, phase changes, density, pressure Pascal's Principle, buoyant force, Archimedes' Principle, Bernoulli's Principle,...

Pupils learn everything from how to take scientific measurements, to accuracy/precision, to density and a plethora of topics from a presentation on the metric system.

Real world chemical reactions are used as examples for teaching stoichiometry. Viewers work through air bag inflation, fat conversion to water in a camel, rocket fuel combustion, and carbon dioxide removal in spacecraft. Make...

Urbanization and how it affects wildlife is the focus of a presentation that uses statistics to make a case for concern and change.

A short exercise explaining the formula for volumetric density followed by several practice problems and examples.
