From seed to plate: teaching food systems
A 6-week module that begins with a single tray.
A food system sounds like a university topic until you realise a single growing tray contains the whole thing: inputs, production, harvest, distribution, consumption, and waste. This six-week module walks a class through all of it, and it works at school or at home.
Week 1, inputs: students examine seeds, growing media, water, and light, and cost them. Where did the seeds come from? What makes a seed certified organic? Week 2, production: sowing day. Students set up trays, agree a care rota, and start their observation journals with height, colour, and moisture readings.
Week 3, growth and risk: the crop is now a responsibility. Classes meet problems, dry patches, mould, uneven growth, and solve them, learning that food does not simply appear. Week 4, harvest: cutting, weighing, and hygiene. The yield number matters; it turns into grams per litre of water and grams per rupee, the arithmetic of every farm on earth.
Week 5, distribution and consumption: the harvest goes somewhere real, the mid-day meal, a tasting counter, or home to families, and students track who ate what. Week 6, waste and renewal: spent media is composted, trays are cleaned, and the class closes the loop by costing the whole cycle and planning the next one.
By the end, 'food system' is not a diagram. It is six weeks of decisions the students made themselves, and a plate they can explain from seed onward.
