Specific Learning Outcomes
Senior 1: Nature of Electricity
Overview
The conceptual development of the particle model of electricity underlies an understanding of electrostatics and current electricity. To develop and test this model, students construct simple devices like an electrophorous and investigate electrostatic phenomena. A transition from static to current electricity enables the learner to investigate circuits and make connections to daily applications like the cost of electrical energy and the safety and efficiency of electrical appliances. Additionally, students investigate hydroelectric power and address sustainability issues associated with the generation and transmission of electricity in Manitoba.
