Here is the laser light contraption that takes sound waves and converts them to visible light wave using a laser. I show how I built it and then some of the things my classes discovered about it. It was pretty fun.

This was our big challenge for the first semester. Take 6 groups each with a different part of a Rube Goldberg machine and then combine them together. The video has three sections, Videos spliced to show what we were hoping for, videos spliced but in slow motion, and finally the actual try, which by the way actually performed the task of flipping a water bottle, as that is the current trend going around at our school at least. After multiple trials we were not able to get all 36 parts to work on a single try. Somewhere, some part would always fail, but all parts worked multiple times. It was entertaining to say the least. Kids were excited.

Students learn to measure with a metric tape, create a spreadsheet that calculates averages, and how to use the Magnus Effect in order to make a bic pen fly across the classroom.
