The course map.
Eight units — four per semester — the labs that anchor them, and the two-day rhythm that runs every week of the year. This is the planner’s view — the whole course on one page.
Two days a week, and the work between them.
Every unit runs on the same rhythm: Concept Day → [student works at home] → Experiment Day → [student synthesizes at home] → next Concept Day. One day forces a choice between depth and breadth; two days allow both. More than two crowds out the at-home work where integration actually happens.
Concept Day
- Arrival & warm-up — reconnect with the prior session
- Pre-lecture discussion — surface what the at-home reading raised
- Direct instruction — micro-lectures, worked problems, demonstrations
- Problem set / model work — apply the concept, solo or in pairs
- Misconception sweep & wrap-up — correct common errors, preview the lab
Guide's role: Socratic and diagnostic. Student's role: active participation; pre-reading required.
Experiment Day
- Pre-lab briefing — the question, the procedure, the safety
- Safety check — goggles and gloves for dissection, sharps care with scalpels & blades; explicit, every time
- Setup — microscopes, specimens, dissection kits, partner assignment
- Execution — the lab itself; the guide circulates and coaches
- Debrief & lab notebook — completed before the student leaves
- Cleanup & specimen disposal — to standard; non-negotiable
Guide's role: safety officer first, teacher second. Student's role: the lab notebook is THE artifact — predictions before results.
From the plant cell to whole ecosystems.
The sequence is deliberate: each unit assumes the one before it. Click any unit to open its mastery rubric — the standard a student demonstrates against to advance.
| Unit | Big ideas | Anchor lab(s) | Integrates with |
|---|---|---|---|
| 01 · Plant Cells & Tissues | The plant cell, cell wall & vacuole, chloroplasts & plastids, meristematic vs. dermal, ground & vascular tissue | Microscopy of plant cells & tissues (epidermis peel, stomata, xylem) | Robert Hooke names the “cell” from cork (history, reading); microscopy technique; scale & magnification math |
| 02 · Roots, Stems & Leaves | Root & shoot systems, primary & secondary growth, leaf anatomy, xylem & phloem organization | Leaf & root structure dissection; stem cross-sections under the scope | The early plant anatomists (history, writing); comparative anatomy; measuring growth rates |
| 03 · Photosynthesis & Plant Energy | Light & Calvin reactions, chloroplast function, pigments, C3 / C4 / CAM, cellular respiration | Photosynthesis rate (floating-disk assay); leaf-pigment chromatography | Priestley & Ingenhousz discover photosynthesis; van Helmont’s willow (history); rate & gas-volume math |
| 04 · Water & Nutrient Transport | Water potential, transpiration, phloem transport, mineral nutrition, mycorrhizae and microbial nitrogen fixation | Approved potometer work; supplied water-potential and plant-microbe datasets | Stephen Hales measures sap flow (history); the physics of capillarity; water-potential calculation |
| 05 · Plant Growth & Hormones | Growth regulation, tropisms, photoperiodism, abiotic stress and biotic defense | 14-day normal-care observation plan; supplied repeated-growth and stress-response data | Darwin’s phototropism experiments (history, reading); growth-curve math |
| 06 · Flowers, Seeds & Fruit | Flower and seed development, alternation of generations, breeding, selection response and ploidy | Flower dissection & pollination study | Gregor Mendel’s pea garden (history, reading, writing); genetics ignored until 1900; probability, ratios & the chi-square test |
| 07 · Plant Diversity & Classification | Plant groups and life cycles, monocots/eudicots, branching phylogeny and identification keys | Dichotomous-key plant identification | Linnaeus & binomial naming (history); building & using keys; cladistics & tree-reading |
| 08 · Plants, Ecosystems & People | Plants in ecosystems, primary productivity, agriculture & crops, conservation | Seed dispersal & fruit survey; productivity estimate | Borlaug & the Green Revolution (history, economics, ethics); engineering; yield & productivity math |
Every unit carries the core spokes — History, Reading, and Writing — anchored to the story in the integration guide. The column above names each unit’s distinctive spokes; geography and soft social studies run where they fit, and students pick from elective spokes (data, ethics, economics, technology, art). An applied-math lane runs through every unit too — math used in service of the science, never as a separate program.
Where mastery gets proven in person.
Three times across the year, the student steps up to a demonstration that cannot be faked, outsourced, or generated. These are the AI-proof core of the course — understanding, shown in real time, against a rubric, in front of a guide.
Plant dissection defense
Dissect a flower, seed, or stem, name each structure, and defend its function out loud, under questions.
Timed plant identification
Key out unknown plants and structures with a dichotomous key — naming and justifying each step, under time pressure.
Oral lab-notebook defense
Walk a guide through your own notebook: the question, the method, the data, the anomalies, the interpretation.
Assigned student learning
Open the eight learning pathways for specific reading sections, explanations, datasets, leveled practice, worked answers, and transfer evidence. Print the student unit pages alongside the separate assessment packets. Broad book recommendations do not replace the assigned sections.
