Students' bags should sit flat on the table with the back facing up. Students glue the flukes to the bottom of the bag. Distribute dorsal fins. Show students how to fold the flaps at the bottom of the fin. Fold flaps in opposite directions for better stability.
Students glue the bottoms of the flaps to the bag of the bag so that the fin stands up.
Glue fin in center of bag. Make sure that the fin curves back towards the flukes. Students color and decorate the fronts and backs of their bags. Students put on their suits. Students pretend to move their noses to the tops of their heads to make a blowhole.
