Geology, taught at the outcrop and the bench.

Most geology courses are a textbook full of diagrams with a few specimens passed around. This one is the reverse. Every week is built around a question you answer at the bench or in the field — with a hand lens, a streak plate, a Mohs hardness kit, a drop of dilute acid on a carbonate — and the reading exists to support that work. That is what "lab-led, not textbook-led" means, and it is the single most important thing to understand about how this course runs.

The course is organized as a two-day rhythm: a Concept Day where the idea is introduced and worked through on paper, and a Field & Lab Day where it becomes physical (a specimen scratched for hardness, a streak drawn, an outcrop read bed by bed) and gets written into a real lab notebook. Between the two days, the student works at home, and that gap is where retention actually consolidates.

Mastery is the progression rule. A student advances through a concept when they can reproduce, explain, and apply it, rather than advancing simply because a week has passed. "Developing" is the honest, expected default; "mastered" is earned and demonstrated. The rubrics are the instrument that makes that judgment fair and repeatable.
