We make our own maple syrup in Michigan and I always used to take my class to the sugar shack for a field trip and let them tap trees and watch the sap boil. Now, I go to classrooms and present to younger kids and take a piece of tree trunk with me and drill a hole from the top down about 2 inches from the side. Then at school I drill in from the side to hit the first drilling and then pound in a tap. When I pour sap down from the top it comes out the tap into a bucket so they can see how it works without actually being there!
