🌿 Plant Zones and Carbon Flow Check

Students analyze sample greenhouse plant cards, light maps, and a short teacher-guided carbon cycling model to confirm which ideas are scientifically workable before drafting one direction. They annotate sketches with likely light, humidity, airflow, and soil moisture needs, then explain how photosynthesis and respiration connect to plant placement and greenhouse comfort. This just-in-time science check helps teams avoid selecting ideas that look calm but would fail biologically.
