Another time we met on a Saturday and carpooled to our local food pantry to deliver canned goods and money we had collected. They gave us a tour and told about their program.
We always try to include photos or a little write up in our church newsletter after the trip.
We also culminated a food collection project (sorry pre-rotation and can't remember what the story was) activity several years back with a trip to our local food pantry.
We made "Linus Project Blankets" for terminally ill children (www.projectlinus.org)as a culmination of a stewardship unit last fall on Wednesday night. Then we took them to our local drop off point in the church vans and took the kids out to view Christmas lights as a treat.
This can also be a good experience in learning about hospitality and welcoming the stranger.
It is daunting to be in a new place, where you don't know anyone, and don't even know where the bathrooms are or how to find your Sunday School room!
We have also found that the students benefit from experiencing different worship styles, while recognizing that the Lord we worship is one and the same.
We have walked, and carpooled. There must always be parent permission slips, and no child will leave the property without it.
We also require volunteer screening forms for all persons who work with children, youth and vulnerable adults.
