Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a...

NOVA explores the basic principle of buoyancy. Also included at this site are some interesting brain-teasers related to the topic.

Instructional module focusing on density as a physical property of matter. Discussion incorporates historical references as well as formulas. Site also includes an interactive practice quiz and links relating to the topic.

Deepen the students' understanding of density by constructing a simple hydrometer that can be used to compare the densities of different solutions.
