This simple model is based on a common woodworking project that, at first glance, seems impossible to un-assemble. The puzzle begins with the two pieces together, forming a cube. The goal is to separate the pieces. The key is knowing that it is actually a combination between two magnets and a steel ball preventing the two halves from sliding apart, not the impossible dovetail joinery.
There are many lessons or uses for the impossible dovetail puzzle in the classroom. I have listed a few of the modeling techniques and/or other ways to use the puzzle in classroom below:
|Modeling Techniques||Post Printing Uses|
|Basic Sketches and Extrusions|
Creating Loft Between 2 Sketches
Introduction to Magnetism Units in Science
Family Game Nights
For each of the modeling techniques above, I have estimated times for teacher demonstrations and student modeling.
|Technique||Corresponding Image||Teacher Demo(min)||Student Modeling (min)|
|Basic Sketches and Extrusions||10 -15||15-20|
