4-h clubs, demonstrations
Agricultural Extension Service, South Dakota State College of Agriculture and Mechanic Arts
Have you ever shown someone how to make a whistle, play a game, make a rope, tie a knot or can some food? If you have done any of these or similar things, then you have given a demonstration, because a demonstration is a method of "showing by doing" and at the same time telling how the process is done. It is one of the best methods of teaching and learning.
