Construct a Sierpinski Pyramid

Construct a modular, fractal structure with tetrahedral shapes.

Wacław Sierpiński is the name of a Polish mathematician famous for extensively describing a certain type of self-similar triangle, which means it’s not only a triangle made out of other triangles but the drawing pattern repeats independently of the scale. This is true not only in 2 dimensions but also in 3 dimensions, where instead of a Sierpinski triangle you have a Sierpinski pyramid.

Building a Sierpinski Pyramid with Strawbees can be done individually but we recommend working as a group to assemble and connect smaller pyramids, also named tetrahedrons. You can make a much bigger and interesting construction as a team.

Building the pyramid alone can be tedious, working in groups is more engaging and effectiveBuilding the pyramid alone can be tedious, working in groups is more engaging and effective

The structure scales and it can get big enough to easily fit students inside
Examining this structure from many perspectives reveals different things about it
Building large Strawbees structures is fun, safe and silent on the fall

Among inventing the first functioning telephone, Scottish Inventor Alexander Graham Bell created massive tetrahedral kites using the same pyramid shapes to build the Sierpinski Pyramid. Watch more about how to build a small kite by Erik in these videos.

If your kite is too heavy to fly make die cut connectors from the Sustainability Station from lightweight plastics or paper!

You can exchange the plastic straws with paper straws rolled by you for a more durable Sierpinski Pyramid to handle the weight!
