Every simulation is freely accessible. No student accounts, no logins, nothing to provision. Link a scenario, and your class is inside it.
Every scenario opens with a concrete question and forces a commitment before the simulation runs. That structure is a ready-made lesson: collect the votes, run the world once, and teach into the gap between what the room predicted and what physics did.
Does a heavier car win the collision? Hands up. The room commits before anyone touches a control.
The sim runs the honest physics while the class prediction stays visible. The room watches its own belief break together.
Unpack explains the why. Explore and The Field give students the controls, in class or as homework, until the corrected model holds.
Mechanics, Waves & Oscillations, Fields, Thermodynamics, Modern Physics. Each branch is built around a question students think they can answer, because the wrong answers are where the teaching is. Nothing is gated: the full library is open from the first visit.
Browse the Library →Branches map to standard units and carry no prerequisites or gating. Start where your syllabus is this week; scenarios inside a branch need no order either.
Every scenario and every open Field sim has a stable URL. Drop it in your LMS, a slide, or an email. No platform between your class and the physics.
Studio drafts a scenario from your own description, on the same physics engine, checked and human-reviewed before it publishes. Useful when the textbook example is not the one your students will remember.
Students meet Maya and Alfy, the resident guides for pattern and rate. They keep a strict rule your classroom will appreciate: they appear only after the reveal, in the explanation layer. They never hint at the answer, never talk over a prediction, and never soften a miss. The prediction moment stays clean.
