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.
