Wall of Death
You will need approx. 12 cards on wool to hang around necks. Make pairs of cards for each first aid situation - e.g. nose bleed, cut or grazed finger, bandage knee, etc. Hang a card around the necks of two girls from each patrol. On word "go", each "tagged" girl holds her hands out as if riding a motor bike, makes appropriate noise, and runs around the hall and touches each wall. When whistle goes, each Patrol finds their "injured" girls and treat accordingly.
