Pottery looks like art class. It is actually crystallography, fluid mechanics, and phase change - all visible at kid scale, and all reversible until the moment it isn't. Here is what a session covers.
Kaolinite is stacks of flat hexagonal crystals held together by weak charge. Water slides between them, which is why clay bends instead of crumbling.
Students do: add water to dry clay a few drops at a time and feel it go from crumbly to bendable - the same platelets, just lubricated.
A bisque pot is full of microscopic holes. That is why it drinks water straight off your finger, and why it cannot hold soup yet.
Students do: drip water on bisque and on glazed ware, then predict what happens.
Glaze is silica plus flux - glass that needs help melting. Same recipe, different atmosphere, wildly different surface.
Students do: compare horse hair, obvara, and naked raku pieces fired the same way.
At 1900°F silica melts and fills every pore, then cools solid. Vitrification is a one-way door.
Students do: trace a piece from wet clay to fired glass and find the point of no return.
Why a mug has a handle, why a vase has a narrow neck, why a wide bowl cools soup faster. Every shape was an engineering decision before it was a style decision.
Students do: design a vessel for one job - carry water, cool tea, hold a candle - and defend the shape.
Three physical steps, then three chemical ones. Students learn all six in a single session.
