Run a Kims Game using First Aid supplies to teach girls what goes into a First Aid Kit.
Various first aid supplies (20-30 items)
Have a number of first aid items hidden from the girls.
One by one, hold these up and have the girls try to remember as many as they can.
At the end, give each girl a pen and paper and have them try to write down as many items as they can remember.
Include a number of items which do not belong in a first aid kit. For older girls, they should try to identify these items as they go. For younger girls you may want them to have a discussion afterwards in their Sixes/groups.
