Icosahedron Planets

In our continuing exploration of geometry, we turned out attention to icosahedrons. The word comes from the Greek word eíkosi meaning ‘twenty’ and hédra meaning ‘seat’. So guess how many sides the largest of the platonic solids have? You guessed it – TWENTY!

This activity came on the heels of learning about Buckminster Fuller (see our prior post on building a geodesic dome) and his Dymaxion Map. He created the only flat map of our planet where all the land masses are connected. That guy was incredible!

We downloaded these super cool templates here. It would have been great to have scaled them up and down to make them more representational of the planets’ relative size, but our printer doesn’t print larger than letter size :0). Maybe for a summer project!

Getting the last folds in place was tricky and even after making 2 planets each, I’m not sure we successfully mastered it, but it was a super fun project.
