The document outlines an assessment activity for reviewing material selection for electrical power lines to reduce resistance and energy loss. The goals are to: state what will be achieved; research and list notes on protocols to reduce resistance; and produce a hypothesis. Additionally, a table of research references must be drawn, analyzing relevance and discussing reasons. A method must be written and other considerations outlined with justifications for the final choice. Good referencing from multiple sources and fully evaluating alternatives are grading tips provided.
