How can you encourage students to question and explore their day-to-day encounters with science and still get through the curriculum for the year? At a local hardware store--you'll discover the solution--a big metal mailbox. It has all the trimmings: a flip door, a red flag on the side, even the approval of the Postmaster General. This is the birth of the mailbox question. This strategy is sure to “deliver” inquiry based learning into your science curriculum.
