Is it an overhead projector, or...?

13/11/2016

Late last year I stumbled across a room filled with old electrical devices that were now obsolete but the school had yet to throw away. What caught my eye was a pile of old overhead projectors stacked up in the corner. My grade nine students were studying a unit on electricity at the time so I saw an opportunity and jumped on it. The directions were to take the projector apart and reassemble it as a new device, then submit it with a report that explains the purpose of the device as well as how the individual components (lights, fans etc) work. Some students took advantage of being allowed to bring in extra bits and pieces from home but overall the project was pretty successful.
