Of Moths and Whiteboards

Like the primal attraction of a moth to a flame, so it is with teachers to whiteboard markers.

I have found that I can't quite write in a straight line.  All of my writing tilts up. My teaching friends have consoled my fear that this problem will never go away.

I have enjoyed drawing things that help as I teach.  Below is how I explained the mechanisms of evolution.  Students grasp the concept of evolution as a gradual change, but have a difficult time answering the "how."  I hope the picture I drew below helped them out.  I'll be interested to see how my drawing (or lack thereof) changes over the years.
