Science Library Update

I know you've heard this several times over the past few weeks, but the science library has once again added a few new Gizmos! Four new Gizmos were put in place earlier this week: Diffusion, Osmosis, Energy of a Pendulum, and Period of a Pendulum. The Exploration Guide and Assessment Questions are under development. While the EG is developed there are occasionally some modifications to the Gizmo.
