Welcome to the Science of Atoms and Molecules (SAM)

SAM is an NSF funded project designed to assist the realignment of high school science disciplines into a physics, chemistry and biology sequence. The project provides sequences of atomic and molecular model-based units that facilitate not only the disciplinary order but also four thematic sequences: Motion and Energy, Charge, Atoms and Molecules, and Light.

SAM uses the free Molecular Workbench system - a powerful environment for creating interactive simulations used around the world.
