To familiarise students with the theme, ‘Natural Vegetation and Wildlife’,…

Experiential (activity-based) learning holds that students build lasting understanding of a topic when they engage with real objects, settings, or phenomena through direct, hands-on activity, rather than when they only receive information passively through listening, watching, or reading.

For the theme 'Natural Vegetation and Wildlife', a visit to a wildlife sanctuary puts students inside the actual natural setting: they see plant forms, animal habitats, and ecological relationships first-hand, use several senses at once, and can ask questions about what they observe in real time. This direct, activity-based engagement is what experiential learning theory identifies as the most effective route to concept-building for a nature-based theme.

• Screening a documentary on the theme delivers visual and audio content through a recorded medium; students remain viewers of a mediated representation rather than participants in the actual environment.

• Inviting an expert for a lecture conveys information through spoken explanation; students listen to a description of the theme rather than encountering it directly.

• Textbook reading and discussion presents the theme through written text and classroom conversation; students work with an abstract, secondhand account rather than the environment itself.

Because it is the only option that gives students direct, first-hand contact with the actual natural setting, a visit to a wildlife sanctuary best fulfils the experiential-learning goal of familiarising students with 'Natural Vegetation and Wildlife'.
