I recently discovered the idea behind provocations. I had been making lists of things that interest the children along with objects that encourage exploration. As I introduce those items, I often make notes on their reactions and thoughts so that I can continue the process!
This site explains which items can be used as Provocations, and explains how they are seen as invitations to learn.
The author of the site also has a great Pinterest board dedicated to Reggio Provocations.
