4 ideas in Class 9 Skill Education, explained in plain words, with games and quizzes to practise.
Rooftop Garden Plan
Part of: Terrace farming
Terrace growers follow a ten-step chart: soil testing, potting mix, germination test, sowing, irrigation with weeding, pest protection, growth monitoring with nutrients, harvest, packaging and transport. Learning trips visit homes, offices, hospitals, hotels and institutes sporting roof farms. Observers log processes, tools with storage, maintenance habits and safety rules like correct tool use and locked chemical stores.
Why it matters. Planned terraces feed families fresh.

- Name five chart steps.
- Name three visit sites.
- State observation heads.
Try at home. Chart your own garden.
Potting Mix Science
Part of: Terrace farming
Roof mixes stay light yet rich: cocopeat, vermiculite or perlite plus compost plus soil in equal 1:1:1 shares, pH-checked as before. Ordinary soil packs dense when wet, starving roots of air, pooling water and rotting roots. Designed mixes stay loose and airy for oxygen and drainage while sparing roofs: one litre weighs about 290 g with perlite but 700 g with soil, a 410 g penalty for the heavier choice.
Why it matters. Light mixes lift heavy harvests.

- State the 1:1:1 recipe.
- State soil's three faults.
- State the weight proof.
Try at home. Weigh your own pot mix.
Seed Wisdom
Part of: Terrace farming
Hybrid seeds promise higher yields but cost more and serve only once, while local seeds harvested with care and saved for next season guard seed security and biodiversity. Packets print germination rates, yet field results swing with moisture and temperature, so depth and spacing follow packet advice or expert counsel. Wise growers weigh price against permanence before sowing.
Why it matters. Right seeds secure harvests.
Try it in two minutes
- State hybrid traits.
- State local seed value.
- State packet facts.
Try at home. Sort seeds by season.
Germination Test
Part of: Terrace farming
Testers first count seeds, then plant them in trays, pots or containers and water on schedule. After two to three weeks they tally sprouts against seeds sown, calculate the percentage, and match it with packet claims. Healthy seedlings graduate straight into rooftop beds, so testing doubles as nursery work and no good sprout goes waste.
Why it matters. Testing saves sowing surprises.
Try it in two minutes
- List five test steps.
- State the waiting time.
- State seedling reuse.
Try at home. Test any pulse seeds.
