This resource contains several mini-explorations using a slide projector as a light source to investigate light and the properties of images. These activities can be used as a class demonstration or as learning stations. This guide also includes information about the "anatomy" of slide projectors and how they work. Learners and educators are encouraged to "tinker" with the equipment to find the best conditions and methods. Note: the cost of the projector is not included in the total cost of materials.
