Fifth grade teachers were looking at some science content GLEs and talking about the systems concept as it applied to Sun, Moon, and stars. The goal was to create some descriptors representing performance levels of 1, 2, 3, 4.
"We could make a 4 represent a student who is able to explain why the appearance of the Moon changes over time."
"I can hear it now: 'God did it.'"
"No, honey. That would be a 1...not a 4."
