What must be true

The course must teach, simulate, assess, and adapt.

Learn the chemical idea with particle-level visuals before controls appear.
Predict what a molecular or reaction system will do.
Manipulate one chemical variable and observe particle + data consequences.
Explain the mechanism and revise from contradictory evidence.
Defend a claim with units, assumptions, and a transfer case.
