The climate leaf was designed to provide an experience of exploration and measurement. A leaf was chosen as the light meter shape to represent how leaves collect and use sunlight. The kit is made to be assembled in 10 minutes. A solar collector, in a simple circuit, is connected to an ammeter to show how electrical current can be derived from the sun in real time. A bubble level allows reproducible measurement in different settings, and a thermometer/hygrometer lets users look for relationships between heat/humidity and current.
