  Mini-Activity: Human Dome
Activites Index | Glossary Educator Support  

Definition Dome A curved roof enclosing a circular space; a three-dimensional arch


1. Have five kids stand in a circle around a soccer ball. The kids should all place their fingertips on the ball and lift it, leaning in toward the center of the circle and sliding their feet back.  
2. Reach into the center and push down gently on the ball. Ask: Where could the dome use more support? (Adding five seated kids as buttresses at the base of each "rib" of the dome will help the dome support more compression. As in an arch, the buttresses exert an inward force on the sides of the dome that balances the outward force created by the load pressing down on the top of the arch.) 
Illustration: kids leaning in, pressing on a soccer ball at the center.
