On Wednesday I taught a group of 8th grade math students how to use geometry in turning. I introduced turning and they all made 5 cylinders. This was to get them used to the idea of putting things on and off the lathe and using the tool rest as a straight edge guide. Then all the students marked the end of wood cylinders, offset, so that everyone could turn an ellipse. Once that was accomplished we marked the ends of another cylinder and made triangles. The kids were great! Just so they could have a functional item to take home we made the ellipses into whistles. Here are some pictures.
