Your Turn!Your Turn!• Research, design and build a Geodesic

Dome.• You may use any dimensions and any

type of material for construction.• You must turn in the dome and a data

sheet showing which dome ratio you used along with all math steps.

• Also show the predicted and the actual dimensions of your dome.
