Idea's for my Photoshoot

I want to take photo's of several students around the college, I want to have a fun group feeling, showing people socialising and studying so that they are related to the college but do not look boring. They should look as natural as possible and not posed. I want the pictures in lots of different locations around college, I will also have to take more photo's than I need so that I can select images that will be suitable for the cover, contents page and will work with the rest of the design. I will take the photo's throughout the week so that I can get a good variety and so that the weather is good.
