A well run project

Some days, it just goes right. The perfect project is one where I spend hours and hours preparing it, but when put in the hands of the students I do almost nothing. If I've planned it right, if I introduce the project correctly, students get to take control and run with it.
Today, it worked. Students moved around the room, asking survey questions they wrote about topics they picked to other students in the room. From my highest students to my lowest, students were gathering data and finding success. I sat back and watched. It felt so so so so so good.
