I'm wondering what kinds of fundraising ideas work well over the summer break for high school students. We've got an expensive trip coming up next year, and I want to make sure all of the continuing students are able to pay for it. They can all earn money in their own ways - babysitting, summer jobs, etc. But for those students who don't have summer incomes, I'm looking for something that I can help facilitate, but that students will be able to accomplish indepedently over the break.
