Chemistry vocabulary words

Chemistry students put their vocabulary words on http://www.wordle.net/
 and then define them.

Boyle's Law in chemistry lab

In this lab the students discovered that pressure and volume are inversely related; as pressure increases, volume decreases.  This lab also had students working with numbers of greater magnitude than they were used to working with.  The graph of volume vs pressure is a hyperbola and 1/V vs pressure turns out to be a straight line.

M.C. Escher

Making GeoGebra tools in Geometry.  Some reminded me of M. C. Escher's work.  Took time to look at some of his pieces.    Used   http://www.photovisi.com/collage/create?template=template8 to do the collage of M. C. Escher.
Repeated designs where made by constructing a geometric shape, making it a tool, and then using the tool many times to create a design.  Collage was again created using photovisi.
