Building a Model of a Geodesic Dome
Based on information furnished by:

It's Child's Play!!!

  IMPORTANT: This is a family project and is best done with adult supervision.

Carefully cut out the paper pattern for the repeating triangle.

Then trace around the pattern on stiff cardboard.

You will need to make 15 cardboard cutouts like this.
 
Use a metal straight-edge and a utility knife, trimming razor or scissors to make the cutouts.

Then mark the "bend line" (from the paper pattern) on to each triangle and score it 1/2 way through the cardboard.

Bend the cardboard along the scored lines and your geodesic "icosa faces" start to take shape.
 
Now all that's left to do is fasten together the edges.

We used duct tape. A hot-glue gun also works.

As the edges are fastened together, the dome starts to take shape.
 

 
And before you know it, your geodesic dome has come to life!!!

Do you see the repeating 5-pointed star pattern?

Technically speaking, this structure is 2/3 of a sphere. Each "icosa face" (repeating triangle) contains 4 sub-triangles. Do you see the icosa faces in our dome?
 
Paper Pattern:
This is what your paper pattern will look like, but bigger.

It is a pattern for "1 icosa face" of a 2-frequency dome. It contains 4 sub-triangles.

2-frequency means that the base of the icosa face measures 2 sub-triangles wide.

 

 "A" lines = 4 and 1/32 inches
"B" lines = 5 and 5/16 inches

Measure accurately!!! It is very important!!!

The "A" lines are the lines you cut on. The "B" lines are the "score and bend" lines.

These plans and patterns are based on resources provided by GoodKarmaDomes.
