A teacher prepares a study tour to a local nursery to connect the plant life…

Concept: NCF 2005's Environmental Studies (EVS) syllabus for Classes III-V is deliberately organised as six integrated themes — Family and Friends, Food, Water, Shelter, Travel, and Things We Make and Do — instead of separate Science and Social Science units. Each theme is designed to braid a natural/biological process together with the social and cultural practice built around it, so a single classroom activity can cover both strands at once.

Application: The "Family and Friends" theme carries four sub-themes — Relationships, Work and Play, Animals, and Plants. The Plants sub-theme specifically pairs a biological process (such as a plant's growth or life cycle) with the community and cultural knowledge that surrounds it (such as how elders and families use plants, including in traditional medicine). The teacher's study tour links the nursery's plant life cycle (Science) to how traditional medicine is prepared from plants (Social Science) — exactly this science-plus-society pairing — so the activity falls under Family and Friends.

Cross-check — why the other themes do not fit as well:

• Things We Make and Do centres on fabrication and production activities — pottery, weaving, construction — and the materials, tools, and processes involved, not on a living organism's growth stages.

• Food centres on what is eaten, food sources, and everyday food habits, not on a plant's growth process or its non-food traditional uses.

• Travel centres on modes of movement and reasons for journeys, not on plant biology or community knowledge practices.

Result: Because the activity pairs a Science concept (plant life cycle) with a Social Science concept (traditional medicine knowledge), it fits the Plants sub-theme of Family and Friends — the correct theme is Family and Friends.
