A great way to raise money for a big trip is to sell food during sporting events or other after school events. Culinary students can actually make the food and decide on a menu and pricing. This allows students to taken ownership for trips that they go on and learn business skills. It is best especially for high school students to show them how to price things and allow them to come up with ideas to market their products. I view it as first a learning experience and secondly an income generator.
