Interactive labs you can run in a browser. Each one is a single self-contained page — nothing to install, no account to make, and no data leaves your device. Pick a subject to browse the labs.
Physics Labs
Thermodynamic cycles on a draggable PV diagram, special relativity from a light clock to cosmic-ray muons, and a projectile-motion challenge where your prediction gets one shot at a moving target.

Chem Labs
Five labs from the Unit 1 chemistry storylines: measure density to identify a suspect liquid, separate a three-part mixture, test six unknowns, run a coffee-cup calorimeter, and read heating and cooling curves.
