In working together, these groups solicit donations or products from local businesses. The donations are put together and associated with a question. In a format similar to the popular game show Jeopardy, contestants from each of the school groups compete for the donations. The event can be staged in the school auditorium. Admission can be charged, concession stands can be set up to sell food, etc.
Local businesses can help advertise the event.
Proceeds from the admission and concession stands can then be divided evenly between all of the competing school groups so that everyone leaves with something for their cause. Sell bicycle helmets.
