Day 99 January 31, 2023 – Opaque Projector

Yesterday I spoke about thermofax machine. Today I will recycle a blog I did several years ago about the opaque projector. The connection to my current teaching is that we had a Social Studies teacher who was notorious for putting a text on the opaque projector and having students take notes on it. For the student, I am sure it was boring but for the teacher, it was a breeze. When he retired we gave him his opaque projector to use in perpetuity.  We did keep finding them in closets for several years but they are all gone now
