Inquiry Spring
Working with springs is a treat for my students. They compress them and watch the results. Without energy applied, there is not much to see and as a result, it's not very engaging for students. My reaction to Wil's metaphor of a spring is that you need to put energy into the inquiry system otherwise nothing happens. The energy input can also be directed to other places on the spring and new results can be observed. In this sense, I like this metaphor for inquiry.
