The Adventurer Law ends with "be helpful, be cheerful, be thoughtful, be reverent." We practise those on purpose, with projects a five-year-old can do and an nine-year-old can lead.
Service in Adventurers is not a once-a-year event. It is written into the requirements at every level, so every child does some of it every year.

Eager Beavers earn the Helping at Home chip. Busy Bees earn Home Helper. Builders earn Family Helper. Chores, done cheerfully, are the first mission field.

Busy Bees "discuss the work people do for your church" and learn one job by helping the person do it. Kids hand out bulletins, help the deacons, sing for the seniors.

Sunbeams explore their neighborhood, list what could be better, and spend time making it better. Builders befriend someone from another culture or generation and invite them to an event.

A multi-grade award every level can earn: learn the story, then do real acts of mercy for people who cannot pay you back.
Sunbeams earn Acts of Kindness; Helping Hands earn Caring Friend. Both ask the child to notice a need and meet it without being asked.
Adventurers can earn an Evangelism patch by taking part in the church's outreach: inviting a friend, helping at a community event, sharing a story they learned.
Parents come along. Adventurer-age children are under parental supervision at all times, at every event, by North American Division rule, so service projects are family projects.
Jesus said the greatest in His kingdom is the one who serves. For a child that means three plain things we say every week: notice people, help without being asked, and be cheerful about it. The uniform is a reminder that other people are watching how an Adventurer behaves, at home, at school, at play.
The Adventurer Song says it: "To be honest, kind and true, to be like Jesus through and through."
