Folio, the notebook that teaches back

Why it surfaced

The site demonstrates lessons including photosynthesis, molecular shape, pendulums, and Ohm’s law, with draggable simulations and embedded comprehension checks. Its promise is unusually concrete: write an idea, watch it move, then teach it in a slide-like presentation.

Folio turns teaching notes into interactive lessons that students can explore, manipulate, and quiz themselves on.
