Day 47: Ray Tracing

Monday, 21 October 2013


Above, my twist on the daily agenda is how I keep track of “did I do this with your class?”. Checklists on the board of major topics, assignments, and upcoming quizzes. I get extra mileage out of this scheme because if I forget, some enterprising kid in the class will ask “hey, how do we ray trace for convex mirrors?” or something.


Today, we practiced ray racing in all 4 classes. The kids are working off this handy notes sheet I made with real spherical mirrors drawn to scale. Afterward, the kids move on to the classwork.

What was the warmup in 7th period today?
