Survival Shelters outlines what to teach 6th grade students about building survival shelters during a Hatchet field day. Students should be taught the 5 W's of site selection including proximity to water, avoiding dead trees, and reducing bugs. They will learn how to construct lean-to and double lean-to (A-frame) shelters using building materials like frames and debris for weatherproofing. The document provides diagrams of completed shelters including use of a firepit and windwall for additional protection.
