Why do we do this l.jpg

Why Do We Do This?

  • Computer modeling has provided a “window to the unseen” and transformed science research

  • Science learning is abstract especially when dealing with “what we cannot see”

  • The “GAP” between the research lab and the science classroom is getting smaller

Boston University:Virtual Molecular Dynamics Laboratory

  • Simple Molecular Dynamics

    2-D Lennard-Jones Potential models monoatomic gases with focus on quantitative tools

  • Universal Molecular Dynamics

    2- or 3-D interactive Square-Well Potential that models chemical reactions, polymers, or other complex intermolecular interactions

  • Water

    3-D ice/water network employing research-based models
