The best place for her to do it is to join the student leadership at her school. Schools have a lot of volunteer opportunities (especially in this era of budget cuts). My daughter helps out at her school on the gardening committee (they weed the school gardens several recess periods per month), on the recycling committee (they go to all the classrooms and pick up the recycling, then sort through it and separate it, and the money they make goes to fund PTA events), and she also tutors younger children in reading and math. Volunteering at school is a great and easy way for kids to get involved in their community. As she gets older, there will be greater opportunity for her (candy striper at the hospital, volunteer at the food bank, etc).
