School Greenhouse Seed Starting Lesson Plan Builder

You are an experienced science and garden-based learning teacher. Build a seed starting lesson plan for a school greenhouse or classroom growing setup.

Grade level and subject: [elementary science, middle school life science, high school biology, agriculture class, environmental science, after-school club]
Learning goals: [germination, plant needs, variables, data collection, food systems, climate, responsibility, sustainability]
Growing setup: [greenhouse, windowsill, grow lights, outdoor nursery, hydroponic tray, raised bed prep]
Seeds available: [lettuce, basil, tomatoes, beans, native plants, flowers, herbs, school garden crops]
Timeline: [one lesson, two-week observation, six-week unit, spring planting cycle, harvest project]
Class context: [student count, groups, period length, indoor/outdoor access, greenhouse rules]
Materials: [trays, soil mix, labels, water, spray bottles, gloves, thermometers, rulers, data sheets, tablets]
Experiment options: [light, water, temperature, seed depth, soil type, scarification, control group, no experiment]
Student needs: [IEP/504 accommodations, language learners, sensory needs, allergies, mobility, behavior supports]
Safety and school rules: [tool use, soil handling, hand washing, mold, fertilizer, pests, heat, glass, food safety, photo policy]
Assessment type: [exit ticket, lab report, data graph, reflection, presentation, garden journal]
Standards or framework: [NGSS, local standards, school garden outcomes, career education, sustainability goals]

Create:
1. Lesson overview with objectives, vocabulary, standards alignment, and success criteria.
2. Materials and setup checklist for teacher, students, and greenhouse space.
3. Minute-by-minute lesson plan for launch, seed setup, data logging, cleanup, and reflection.
4. Germination experiment design with variables, controls, predictions, and fair-test cautions.
5. Student role cards for seed manager, label checker, water monitor, data recorder, and cleanup lead.
6. Data log template for date, germination, height, leaves, moisture, temperature, and observations.
7. Differentiation and accessibility supports.
8. Safety, hygiene, allergy, mold, tool, and food-growing checklist.
9. Follow-up schedule for care, measurement, transplanting, and troubleshooting.
10. Assessment rubric and extension ideas for harvest, compost, pollinators, or community sharing.

Do not invent school safety rules, pesticide guidance, food safety permissions, or local standards. Flag all greenhouse, allergy, tool, and food-growing policies for teacher or administrator verification.
