Engineering Principles 1 helps students understand the fields of engineering and engineering technology. Mechanical and electrical engineering are emphasized. Topics include: an overview of engineering and engineering problem solving; work, energy and mechanical power; energy resources, conversion, and efficiency; electromechanical applications; circuits and instrumentation; thermal applications; and the completion of an Engineering Field Career Research Portfolio. In addition to including approximately half of the PLTW POE content, Engineering Principles challenges students to complete additional related, extended projects of interest.
