PUMAS (poo' • mas) -- is a collection of brief examples showing how math and science topics taught in K-12 classes can be used in interesting settings, including every day life.

The examples are written primarily by scientists, engineers, and other content experts having practical experience with the material. They are aimed mainly at classroom teachers, and are available to all interested parties via the PUMAS web site.

Our goal is to capture, for the benefit of pre-college education, the flavor of the vast experience that working scientists have with interesting and practical uses of math and science.

Thermo and Fluid Dynamics of a Homemade “Lava Lamp” by Dan Miller
Lava lamps are just cool, that’s all there is to it. Most everyone has spent at least an hour of their life just staring at a lava lamp. While the experiment outlined here isn’t really the same as a commercial lava lamp it does demonstrate many of the important fluid and thermodynamic properties. Most importantly it provides students with an interesting and fun visual demonstration intended to motivate thought about the physics behind the experiment itself.
