Help your students visualize molecular motion concepts with this dramatic demonstration device. Just pour the simulated molecules (BBs) into the clear acrylic chamber, and focus it on your classroom overhead projector. By varying the number of molecules and movement of the apparatus, you can illustrate the structure of substances in various states, such as solid, liquid or gas. Random molecular motion, molecular distances, kinetic theory and molecular structure of specific substances can all be illustrated with the same device. The kit includes the reaction chamber, the BBs and teacher notes.
Concepts: Molecular motion, kinetic molecular theory.
Time Required: 15 minutes
Materials Provided: Molecular Motion Demonstrator, copper shot.
