LASER Lissajous patterns..geometric designs /// Homemade Science with Bruce Yeany

This homemade laser light show device produces different geometric designs that change as adjustments are made to it. The laser beam bounces from one spinning mirror to a second one and will change the pattern as the mirror speed varies from one to the other. Homemade science is a collection of classroom tested ideas, suggestions, projects, and experiments that I have used in teaching physical science for the Annville-Cleona school district in central Pennsylvania. I am currently in my 38th year of teaching. My intention is to share these ideas with other teachers or anyone who has an interest in science. I have found that designing and building my own equipment has taught me more than any course that I have ever taken. I hope that you consider trying this for yourself.. I also share and show some of these ideas at workshops, science conferences, or inservice presentations.
