The Structure And Motion of Matter (SAMM) Survey

© 2010 Marilyne Stains and Hannah Sevian 

The SAMM survey is a 15-min, open-ended survey that evaluates students' implicit assumptions about the structure of solute and solvent substances in a gas solution, the origin of motion of the gaseous solute particles, and their trajectories.
