This is a simple project. Set up a video camera. Ask students individually or in pairs to take a seat. Then ask them a few questions. Edit it together and you will have a unique window into your school community. 

Wenona School has done this beautifully. This video has a natural conversational feel to it. Hearing what students say about your school can be much more effective than the Principal or School Tour leader saying the same thing because it is perceived as more authentic.
