I would create the list by noting the activities in reverse chronological order (most recent first). That way they can see what activities you have been in involved in most recently and progress down the list. Alphabetical order may seem like a good idea but it puts everything out of context with activities next to each other than may have been an interest of yours years apart. The reverse chronological order method keeps everything in context. It's always important to list the most recent activities first. Next to each activity note the time frame you participated in it, and possibly the affiliation (school, church, community).

put it in alphabetical order
