If you are bursting with school spirit…
Talk to your school principal about hosting a decorating contest (i.e. lockers, classroom doors, hallway posters, etc.). Be sure you get the appropriate approval before starting to publicize your event. Consider holding your contest during homecoming or another time when school-spirit events are planned. All high school students and faculty may vote and the contestant who raises the most money wins a prize (such as recognition in the school newspaper and a gift certificate, for example)
