Concept:Field visits are practical learning experiences that connect science theory with real-world observation and interaction.Explanation:Field visits take students outside the classroom to explore natural or man-made environments. Learners directly see, touch, and investigate scientific phenomena. This hands-on approach makes concepts clearer and more memorable. It sparks curiosity and develops observational skills. Unlike textbook study, field trips encourage active participation and deeper understanding. They align with NCF-2005, which stresses science education that is true to life and the learner.
