Field trips and excursions provide hands-on learning experiences outside the classroom that are planned to supplement lessons. They stimulate students' interest, help concepts come alive, and foster observation skills and personal development. Proper planning is needed - choosing relevant locations, obtaining permissions, arranging transportation and accommodations safely. Teachers must take precautions for student control and health. Follow-up after trips includes addressing student questions and having them write about what they learned to help solidify knowledge from the experiential learning.
