The document is a geography worksheet about a Stevenson screen, which is a white wooden box fitted with louvres and placed on stilts in an open space. It is used to shield weather instruments from direct sun and rain while allowing air flow. The screen must be painted white to reflect sunlight, made of wood for stability and ventilation, have louvres for air flow, and be elevated in an open area to properly record weather elements. The worksheet asks students to identify the best location to place a Stevenson screen and explain why other sites would not be suitable.
