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 ...

 Andre made a stellated icosahedron. Notice that each point is a different color ... very unusual and attractive.   Back to Top Ben made 5 intersecting tetrahedron. You can see almost the entire green tetrahedron.   Back to Top 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.   Back to Top 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. Catherine built a Great Dodecahedron. You can see a yellow, pentagonal face to the left and front. There is a light turquoise face on the right hand side. Back to Top Diana also made a Great Dodecahedron. We can see her pink, yellow, and pale green pentagonal face very clearly. Beautiful. Back to Top Dina made a Stellated Icosahedron. You can see a pink pentagram (5 pointed star) in the background of the figure. Looking at the polyhedron from the left, you can see a red pentagram. Beautiful! Back to Top Emily made a Stellated Icosahedron in different shades of blue. Beautiful ! Back to Top Erica made a stellated icosahedron. Notice that from the left view you can see a pale blue 5 pointed star. From below and to the left, you can see a purple star. From the front you can see a pink star. Neat ! Back to Top Esther also made a Great Dodecahedron. Beautiful ! Back to Top Francesca made an octahedron (black polyhedron) pierced by a hexahedron (pink cube). Back to Top 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. Back to Top 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. Back to Top Gyu made an incredible Great Icosahedron. This figure contains 120 individual pieces to accurately cut and glue together. Awesome! Back to Top Jackie made the Sixth Stellation of the Icosahedron. I think it look like a medieval weapon? Back to Top Jake made a Great Dodecahedron. Back to Top 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 ! Back to Top Jenny made two perfectly matched tiny and large Great Dodecahedron. Very fun ! Back to Top Jeremy created a beautiful Great Dodecahedron. Back to Top Jonathan made a Stellated Octahedron. Imagine an octahedron and place a point on each face. Voila ! Back to Top Juhin made two intersecting tetrahedron. You can see almost the entire yellow tetrahedron. Back to Top Kamerry had a hard time with this creation. It is a Small Dodecahemicosahedron. Very hard to do. Great job.   Back to Top Kayleigh made a beautiful Stellated Icosahedron. Notice that you can see a green 5 pointed star facing left; a yellow star facing up; and an orange star facing the camera. Back to Top 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.   Back to Top Kristina made an outstanding polyhedra. This is the Sixth Stellation of an Icosahedron. Pretty amazing ! Back to Top Lauren made a pastel rendition of 5 intersecting tetrahedra. You can see the yellow tetrahedra almost completely. Back to Top Leslie gave her Great Dodecahedron some extra visuals. Back to Top Lily made an Icosidodecahedron. The name means that it is a combination of an icosahedron and a dodecahedron. Back to Top Lin made a very difficult polyhedron. This is called the Great Icosahedron. This is a confusing polyhedron to build but Lin did a perfect job. Awesome! Back to Top Marina made an incredibly beautiful mobile. She dangled five, two intersecting tetrahedra from fine strings to make a beautiful piece of art. Back to Top Matt made two intersecting tetrahedra. You can see the light blue tetrahedra almost completely. Back to Top Mayaan wanted to create a 3-d Star of David. I think he did it beautifully. Back to Top Oleg created a Great Icosahedron. This figure contains 120 pieces that need to be accurately cut and glued. The color arrangement is frustratingly difficult. Oleg did a marvelous job. Back to Top Sade made a Stellated Octahedron. Imagine an octahedron (8 faces) with a point attached to each face. Back to Top Sara made an Icosidodecahedron. It's name implies that it is a combination of an icosahedron and a dodecahedron. Beautiful ! Back to Top 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 ! Back to Top Sari created a model of 5 intersecting tetrahedra. You can see a yellow tetrahedra almost completely. Beautiful! Back to Top Shir made a perfect model of an Octahedron (red, eight-sided figure) compounded with a hexahedron (yellow, six-sided cube). Back to Top Stephanie made a beautiful, pastel, Great Dodecahedron. Back to Top Steven must have been enjoying himself. He created two amazing figures. The figure on the left is a lovely Great Dodecahedron. The polyhedra on the right is the sixth stellation of an Icosahedron. awesome ! Back to Top Josh made a beautiful model of 5 intersecting tetrahedra. We can see the green tetrahedra almost completely. Very neatly done! Back to Top Travis made a lovely model of five intersecting tetrahedra. We can see a green tetrahedron almost completely. Beautifully constructed! Back to Top
