1. Stellated Icosahedron

2. Part 1: You will build this first:

3. Part 2: You add the stellation points:

4. Anyone goofing off with materials will be banned from the project.
WARNING:
Anyone goofing off with materials
will be banned from the project.

5. To begin you make the center which is the ICOSAHEDRON.
You should use only one color on this part.

6. Prepare the materials:
Captains pick up a bag of straws and pass out 45 straws to each person (no more, no less!)
Learning Facilitators pick up a gallon-sized baggy for each table member and one sharpie.
Each student:
Write your name on your baggie.
Cut each straw in half. (Cut carefully one at a time. They need to all be approximately the same size.)
Take off the straw wrappers and recycle.
Store straws in the baggie.
Cut off a long piece of ribbon. This will be the color for the center icosahedron.

7. Step 1:
Take a long stand of ribbon and place five (cut) straws

8. Step 2: Tie it together to make a pentagon
Step 2: Tie it together to make a pentagon. (Make sure every time you tie it, it’s a double or triple knot and is tied very well!)
NOTE: Leave a tiny bit of wiggle room in the pentagon so it wiggles with ease.)

10. Step 4: You are transforming the two pentagons to look like this next figure. It will look like a giant bracelet.

16. They will be a little lopsided!

18. Woohoo! You made it all the way around. This is the hardest part.
What we have so far is like a large bracelet. To finish the icosahedron, you have to fill in these tow pentagons.

19. Step 10:
Add TWO straws to the ribbon. Attach the ribbon to
an adjacent vertex
of the same pentagon.

20. Step Eleven: You want to use t he triangle that those two straws created to help fill in the pentagon. To do this you need the ribbon to be at another vertex. Feed the ribbon through the edge/straw to get to the next vertex:

21. Turn over the project to make it a little easier.

30. Woohoo! A complete icosahedron!
Tie off the ribbon and cut it off.
You’ll reattach a new color (if desired) for the points.
