Overhead Projecter

An overhead projector is a form of a projector that displays an image onto a pull down scree, or wall. It is used to make images larger. Usually, teachers will make a transparency ( a clear piece of plactic with a worskeet on it) to let the class see an image enlarged. The overhead can also be used by teachers who just write right on the screen on the projector instead of making a copy of a worksheet.
