Every unit runs with standard physics-classroom equipment, and every demo and lab has a documented online fallback — so you can gauge feasibility for your classroom. Teachers with an existing account get a per-unit Teacher Guide (supplies, prep, safety, and warm-up facilitation) beside each unit on the Handouts page.

New teacher sign-ups are currently paused.
Existing teacher accounts remain active.
Phab Physics has reached its current teacher-account capacity.
New teacher accounts are not being accepted right now. More spots may become available near the end of September as I evaluate hosting costs. Existing teachers can continue to
