From confused in September to confident in May
Each section below is a chapter in your student's env. science story — plain language on one side, an interactive resource on the other.
Unit 1 · Foundations
Food webs finally make sense — when you see who eats whom
Every ecosystem is a web of eating and being eaten. When we trace energy from sunlight through producers, herbivores, and predators, the whole picture snaps into focus — and those worksheet questions stop feeling impossible.
Food Web Builder — Drag & Label Diagram
Place 14 organisms in the right trophic levels. Instant feedback, printable answer key, vocabulary sidebar.
Unit 2 · Cycles
The carbon cycle isn't scary — it's just atoms taking a very long road trip
Carbon moves from atmosphere to plant to animal to soil and back again across millions of years. Once students see it as a journey rather than a memorization list, the AP multiple-choice questions answer themselves.
Carbon Cycle Flowchart — Annotated Study Sheet
Full cycle with reservoir sizes, flux rates, and a human-impact overlay. Illustrated margins, key vocab highlighted.

Unit 3 · Biodiversity
Biodiversity indices: the math that tells you if an ecosystem is healthy
Simpson's and Shannon's indices turn species counts into a single number that describes ecosystem health. We walk through the formula step-by-step with real data from a Pacific Northwest watershed so the numbers feel grounded.
Biodiversity Index Calculator — Guided Worksheet
Real species data, step-by-step formula walkthrough, comparison scenarios, and an AP FRQ practice question at the end.
Unit 4 · Human Impact
Bioaccumulation: why the fish at the top of the food chain carries the most toxins
Each trophic level concentrates persistent chemicals like DDT and mercury — a concept that shows up on the AP exam every single year. We use a Great Lakes case study with real concentration data so students can write the FRQ from memory.
Bioaccumulation Case Study — Great Lakes PCBs
Real EPA concentration data, trophic level diagram with magnification factors, and three AP-style FRQ prompts with model answers.

From tears to that clicks
My daughter was in tears over the nitrogen cycle worksheet. We pulled up Biome at 9:30 PM and by 10:15 she had every blank filled in and actually understood why. Her teacher wrote 'excellent explanation' on the paper.

Mom of a 10th-grader, Austin TX
As a homeschool dad I was winging the ecology unit. Biome gave me a semester's worth of sequenced material — the kids actually ask to do science now. The watershed case study had my 12-year-old writing two pages unprompted.
Daniel Okafor
Homeschool parent of 3, Portland OR
I needed a 4 on the AP exam to keep my scholarship. The biogeochemical cycle resources here are the clearest I've found — better than my textbook. I got a 5. I cried. My mom cried. We both cried.
