More than mere eye appeal, the colors of this poster are symbolic. Each predominant color - brown, yellow, green, red, and blue - represents a type of energy or resource. The activities on the poster's reverse side correlate to the color coding and aid students in carrying out an energy audit of their school that leads to learning about operations and maintenance, energy conservation measures, and adaptations to renewable resources. Grades 5-10, 23" x 35", Full Color, B/W back.
