Supporter early access for AP Physics teachers — AP Physics 1 and AP Physics C — handouts stay free for everyone
🎓 Want to know what you're signing up for? The About page covers the philosophy, a live demo, and everything that's included — plus the 5-minute orientation and the features tour.
Every unit runs with standard physics-classroom equipment, and every demo and lab has a documented online fallback — so you can gauge feasibility before signing up. Signed-in teachers get a per-unit Teacher Guide (supplies, prep, safety, and warm-up facilitation) beside each unit on the Handouts page.
