BSA provides the troop program feature guides as a resource for Boy Scout troops. A PLC can use these guides to plan a series of meetings and outings around a single theme. My post Troop Program Features for Meetings and Outings has more information about these guides.
The plans for the First Aid troop program feature can be found in Volume 2 of Troop Program Features from BSA:
Having agreed to live by the Scout Oath, Scouts pledge themselves to help other people at all times. Often, all that takes is an observant eye to spot a person in need of assistance, and then the kindness to lend a hand. But sometimes, especially when somebody is ill or injured, being helpful takes skill and knowledge, too. That’s why Boy Scouts have been learning first aid since the earliest days of the Scouting movement.
The focus of the First Aid troop program feature is learning to assess an emergency and practical first aid skills. Younger Scouts can work on early rank requirements related to first aid. Older Scouts can focus on the First Aid Merit Badge and the Emergency Preparedness Merit Badge..
The feature event for the program theme is a “disaster day”. Scouts are presented with realistic situations where they can assess the problems and determine what type of first aid to perform.
