Students tape multiple strips into the book and investigate how different page positions affect the resulting folds. In one experiment, most of the pop-ups are asymmetric (different page positions on either side) while in the other they are all symmetric (same distance on each side). Through these experiments, the students discover the answers to these questions:
If a pop-up is asymmetric, on which side will the fold will the fold be?
If two strips are taped symmetrically, but at different page positions from each other, how will the resulting pop-ups be different?
For each student:
Scissors and tape
Ball-point pen and ruler for making sharp folds. The pens don’t have to write
