Why not try volunteering? We are looking for volunteers to help promote Rise #bakery which is a #socent and is part of Providence Row - a fantastic chariety that supports homeless and vulnerable people. https://speedvolunteer.london.gov.uk/opportunities/2e9ee1cb-7dc7-4c57-953c-b636b0b8f847
One community service project seemed to lead to another for Michael Patterson, grown homeschooler. He shares a variety of service project ideas in here that could work for your family. And as Michael reminds us, "Kids don't have to wait to become adults to be heroes."
Hands On Greater Portland is a clearing house for volunteer projects. Their calendar lists age groups suited to each project and the "advanced search" option allows you to find projects for the whole family.
PebbleTossers is a great site that lists volunteer opportunities for kids and families (and makes it easy to participate). Thoughts - 1) we could try to get projects listed on the site and 2) we could create a website similar to this someday where people can sign up to help with neuroblastoma (help with fundraisers, coordinate with other places for things that directly affect families, etc.) Will work more to type out ideas on this to be more clear
