The document outlines a lesson plan using an inquiry training model to teach students about the merits of cooperative societies, with phases including encountering the problem, gathering data through asking yes/no questions, group discussion and experimentation to form rules about the merits, and analysis of the inquiry process used. The lesson plan is designed to develop students' inquiry skills like observing and classifying while learning that cooperative societies ensure continuous existence, mobilize savings, protect members from exploitation, and give equal voting rights.
