When I was in graduate school, we kept a moon journal for a class on observation.  I realized I had not paid much attention to the moon over the years.  Each night I would step into the darkness and spin around until I found the moon.  My journal sketches show the moon changing, first just a sliver, gradually filling the darkness with light, and finally fading to a glimmer as it waxed and waned.  Some nights, the sky was filled with clouds and I would write instead of draw.  The words in my journal reflect my curiosity about the moon, a constant I had not considered in the past.  I wonder what might happen if we watched our students with this same kind of curiosity?
