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
Ecosystems & Energy Flow
Trophic levels, food webs, the 10% rule, primary productivity, and keystone species.
Unit 02
Biodiversity & Populations
Species diversity, population growth, carrying capacity, and survey methods.
Unit 03
Biogeochemical Cycles
The carbon, nitrogen, phosphorus, and water cycles, and how they interlock.
Unit 04
Human Population & Resource Use
Demographic transition, resource demand, and ecological footprints.
Unit 05
Water Resources & Pollution
Watersheds, water quality, dissolved oxygen, nitrate, and turbidity.
Unit 06
Air, Atmosphere & Climate Change
Air pollutants, the greenhouse effect, acid rain, and reading climate data.
Unit 07
Land Use, Agriculture & Waste
Soil, agriculture, land-use change, and solid-waste management.
Unit 08
Sustainability & Environmental Policy
Renewable energy, conservation, and environmental law.
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
Field quadrat / transect defense
Defending your sampling design, data, and conclusions after a real field survey.
Demonstration
Timed data interpretation
Reading an unfamiliar environmental dataset — trend, mechanism, uncertainty — against the clock.
Demonstration
Oral lab-notebook defense
Standing behind your own field notebook — methods, data, and reasoning — out loud.
