Mastery rubrics.
One rubric per unit, plus the three demonstration rubrics. Every rubric uses the same three levels — Not yet, Approaching, Mastered — so the bar is identical for every student.

How the rubrics work
The grading philosophy behind every rubric — decisions not points, a vocabulary published in advance, three tokens that absorb a bad day, and how unit mastery becomes a letter grade.
Unit rubrics
A mastery rubric for each of the eight units. Each one names exactly what a student must be able to do — not how many points they earned — to reach Mastered.
Unit 01
Kinematics & Motion
Position, velocity, and acceleration, the three motion graphs, and free fall & projectiles.
Unit 02
Dynamics & Newton's Laws
Newton's three laws, free-body diagrams, forces on inclines, and friction.
Unit 03
Circular Motion & Gravitation
Centripetal acceleration, the force that supplies it, universal gravitation, and orbits.
Unit 04
Energy & Work
Work as force through a displacement, kinetic and potential energy, and conservation of energy.
Unit 05
Momentum & Collisions
Momentum and impulse, conservation in an isolated system, and elastic & inelastic collisions.
Unit 06
Simple Harmonic Motion
Restoring forces, the period of a spring and a pendulum, and energy in oscillation.
Unit 07
Torque & Rotational Motion
Torque as force times lever arm, static equilibrium, rotational inertia, and angular momentum.
Unit 08
Fluids & Pressure
Density and pressure, how pressure grows with depth, Archimedes' principle, and Pascal's principle.
Demonstration rubrics
The three live demonstrations a student defends in person. These are the AI-proof assessments — you can't paste your way through any of them.
Demonstration
Apparatus build-and-defense
Building a rig to measure a physical quantity, then defending its design and result out loud.
Demonstration
Timed prediction-and-test
Predicting where a projectile lands or how a collision ends, then running it live against the clock.
Demonstration
Lab-notebook defense
Standing behind your recorded methods, data, and reasoning out loud.
