Fog Machines, Vapors, and Phase Diagrams Ed Vitz
This series of demonstrations elucidate the operation of commercial fog machines using common laboratory materials and can be adapted for elementary through tertiary levels. The formation of fogs is discussed in terms of the phase diagram for water and other chemical principles.

Building a Successful Middle School Outreach Effort: Microscopy Camp R. Lee Penn, Leslie Flynn, and Page Johnson
Microscopy Camp is a middle school outreach program designed to introduce and reinforce concepts regarding the atomic structure of crystals. Students synthesize magnetite nanoparticles and characterize them using light, scanning electron, and high-resolution transmission electron microscopy.

Classifying Matter: A Physical Model Using Paper Clips Bob Blake, Lynn Hogue, and Jerry L. Sarquis
By using colored paper clips, students can represent pure substances, mixtures, elements, and compounds and then discuss their similarities and differences. This model is advantageous for the beginning student who would not know enough about the detailed composition of simple materials like milk, brass, sand, and air to classify them properly.
