Subscription Virtual Lab Platform — PhysicsSimulation.org

The simulations built for Edukul were good enough that schools and students outside the institute wanted them. That needed a different product: one that anyone could find, try and pay for, and that a teacher could use with a whole class.

Access is a set of shelves: a free shelf anyone can open, a trial shelf for new accounts, one-class plans, and Pro and Teacher plans that open every lab. Teachers make classes, pick each class's labs and students join with a code.

The simulations are synced from the Edukul codebase rather than forked, so a fix made once reaches both sites.

Every lab ships with a teaching kit — lesson plan, questions for the class, a printable quiz and the key formulas — because a teacher needs a lesson, not just an animation.
