Engineering With Triangles and Geometry: Modular Construction Build Techniques

In this four week course, we will learn about the importance of the triangle in engineering and construction.  Because it is the strongest polygon, it can be used to create structures that are incredibly strong AND lightweight.  We will make triangle based pyramids with one, two, and three unit bases, and examine how simple pyramids can be used to create much larger fractal structures.  We will look at the constructions of Buckminster Fuller and learn about icosahedrons and the importance of strut length in geodesic domes and spheres.  We will make both a V1 and a V2 sphere, paying careful attention to measuring and placement.  We will pause during construction of the spheres and consider how domes can be used to make shelters and dwellings.

Week One: Build small triangle based pyramids, and use four of these units to create medium pyramids.  Discuss safety of using hand tools and working with sharp wires.
Week Two: Build four medium pyramids and use four of those to create a large pyramid, illustrating a fractal structure.
Week Three: Build triangle units and assemble into a icosahedron, also known as a V1 geodesic sphere.  Begin building pentagon units.
Week Four: Finish building pentagon units and assemble into a V2 geodesic sphere.

We will be using math and geometry skills, and crafting skills of measuring, cutting, fastening, and selecting color for impact.

Materials and tools for this course are simple: straws, pipe cleaners, ruler, sharpie, scissors, and household wire cutters and pliers.  All finished structures are lightweight and can be hung from the ceiling or displayed on a shelf.  

I will be building these structures right along with you.  I have a second bird's-eye-view camera focused on my work surface so I can clearly show how the parts go together.  Because of the modular nature of these constructions, there is plenty of opportunity to create new, unique designs and to work independently on new ideas.  You are only limited by the number of straws and pipe cleaners you have on hand!
