During the 2011 summer, 35 youth participating in the Summer Learning Program at the Boston Nature Center, a property of the Massachusetts Audubon Society, stood in a grass field and launched their self-designed kites. There was a lot of running, limited string, and low flying. When a teacher's kite started to edge higher, all eyes focused. The teacher challenged the youth to let the kite string go a little. She circulated to help the youth while keeping her own kite high in the sky. Forty-five minutes later, the sky was full to the tree tops with colorful flyers. This activity was followed by an experientially-based math class lesson on altitude, energy, and aerodynamics.
