Polyhedra Creations

by Oak Hill 8th Graders

Teachers can find lesson plans and instructions for these projects here.

Oak Hill 8th graders completed construction of 3-d shapes as an investigation of what could be made from regular, 2-d shapes. They compounded, stellated, and truncated the 5 Platonic Solids which are shown below.

And here is what they created ...

stellated icosahedron

Andre made a stellated icosahedron. Notice that each point is a different color ... very unusual and attractive.

great dodecahedron

Ben made a Great Dodecahedron. Notice that we are looking at a black pentagonal face with a star shaped cookie on top. If you view this polyhedron from the left, you see a purple pentagonal face with another raised cookie.

Cas built a totaly red stellated icosahedron. An icosahedron has 20 faces. So this is what you would get if you put a point on each face.

Diana also made a Great Dodecahedron. We can see her pink, yellow, and pale green pentagonal face very clearly. Beautiful.

Frank made a Truncated Icosahedron. This ball-like shape is made from pentagons and hexagons. The other name for this polyhedron is a soccer ball.

stellated icosahedron

Greg made a Stellated Icosahedron. He is holding it to show the green pentagram (5 pointed star) that is in the back plane. From above we can see a yellow star. and, from below, we can see a dark blue star.

dodecadodecahedron

Jenn created a Dodecadodecahedron. From the front, we can see an orange pentagonal face with a parallel face that contains an orange pentagram. In the same way, the red pentagonal face on the left has a raised, parallel, red pentagram face. Cool !

Isaac made a beautiful Great Dodecahedron. Notice that we are looking at an orange pentagonal face with a star shaped cookie on top. From the left you can see a white pentagonal face. From below you can see a dark blue face and from above, right, you can see a lavender face.

Sarah made a Great Dodecahedron. She used only shades of blue. You can clearly see the back, white, pentagonal face with a raised blue star-shaped cookie on top. From the bottom right, you can see a light blue pentagonal face. From the bottom left you can see a dark blue face. Gorgeous !
