Fold-Up Paper Projects

My k-8 classes have been exploring different tools we can use with simple materials like craft paper, coincell batteries, LED's and brads. We have been talking a lot about using tools like scissors, paper straws, hole punches and our Glowforge to produce machines with a construction paper chassis that folds up from a symmetrical 2D geometric net into a 3D structure. With the fish in the photo there is a simple brass brad as an eyeball, but it is also the lynchpin of the whole structure, that when taken back out allows the fish to unfold and allow change the battery, change the LED's or modify the paper chassis design. The idea is to make projects that can easily come apart for rapid design interactions by the students.
