Community service is when you volunteer in places you are interested in such as church, the humane society, or a food pantry, etc. You can help neighbors or do clean up days in your neighborhood.
Volunteering for family (aunts, uncles, parents, grandparents) is NOT community service. Babysitting for your siblings or cousins is NOT community service. You should do things for family because you are part of a family. You cannot get paid for community service.
You can volunteer as part of a group at Church, a youth organization or local non-profit.
You can create a food drive or organize an activity that is designed to help a need in the community.
