I had the great pleasure of going along to see BREATHE in action at a school last week. This is a FABULOUS opportunity for schools to get young people thinking about spirituality. It's very gentle and yet powerful. I watched two different age groups engaging with it and it was amazing to see them really getting into it very quickly. There are twelve stations some of which deal with the idea of self, the world, others and God. Most of the stations are reallt tactile or visual and others invite some really good personal reflection.
If you're looking for something spiritual rather than "religious" for some schools work I recommend this highly. You can hire it for a day with a host (or several days - at discounted rate for additional days) and timetable it into the school day and if you like it you can even buy in to the package. It takes slightly longer than a standard school period to do all the stations but the experience is not too adversely affected by doing only some. On Friday several of the pupils came back in their break and lunch hour to do some of the stations they hadn't managed. I think that's a pretty good recommendation.
If you want to know more, have a look at the site and you can even download a flier or listen to one of the tracks.
