For one of our class activities the girls decided that they want to do a service treasure hunt. The idea was presented that the girls are given a service assignment. (All service assignments had been previously determined and arranged).
The girls show up at their arranged location to perform the service. When they are finished there is a new envelope waiting. Inside is a clue for their next service. This continues for as long as your time allows. If they correctly figure out and follow the clues they will be led back to a "treasure" at the ward building or a leaders home.
The thing that makes this worth while is that we contact ward members before hand to set up service that they need done. For example, weeding a certain section of the yard, sweeping out gutters, sweeping off porches, picking fruit, folding laundry, loading the dishwasher or doing dinner dishes or reading a bedtime story to young children.
We split up into groups of 2-3 girls with each group having a leader nearby. It is a race to see who can find the treasure first.
This activity is a huge hit. Beware that it does take some preparation with the class president to get all the service activities lined up, the clues written and everything delivered. Let's face it, the best activities take work :)
Pictures to come later.
