Method demonstrations provide an excellent 
of training 4-H Club members in both leadershi 
subject matter. In addition, they provide a me 
showing other groups · what the members have learn 
th~ir 4-H Club work. 
Training demonstration teams apparently is 
difficult unless we make it so. Demonstratio 
4-H Club members can be made easy if simplicit 
encouragement is adhered to. 
The method of developing demonstrations as 
sented in this circular is not unique, but rather 
been proved by many. Both Extension Agents and vo 
tary 4-H ·Club leaders have. used this method suc 
fully ih training. demonstration teams in the var 
phases of Agricultur~l Engineering.
