=8.3 Electrical Energy in the Home (30 indicative hours)=

//Contextual Outline//
 Electricity is an essential energy source for modern living. Disruption to supply or isolation can lead to the development of alternative methods of obtaining this essential energy resource. For electrical energy to be useful it must be harnessed through the use of an electrical circuit and an energy-converting appliance.  As electricity became increasingly used as the main power supply in homes and electrical appliances became an integral part of daily life for many Australians, the dangers associated with electricity became more prominent. Voltages as low as 20 volts can be dangerous to the human body depending on the health of the person and length of time of contact with the current. Safety devices in household appliances and within the electric circuits in the home can prevent electrical injury or assist in reducing the potential for electric shock.  This module increases students’ understanding of the history, nature and practice of physics and the applications and uses of physics.

//Values and Attitudes//
During this module, teaching/learning activities should allow students to reflect on personal and societal choices and responsibilities about energy production and consumption. There should be an enhanced understanding of the impacts of the provision of electrical energy on the environments from which the necessary resources are obtained and those environments in which electrical generation and transmission occur. Often the decisions Governments make are compromises e.g. coal mining is allowed if associated with conservation projects and these issues could provide opportunities for class debate. <span style="FONT-SIZE: 11pt; FONT-FAMILY: Arial; mso-bidi-font-size: 10.0pt; mso-bidi-font-family: 'Times New Roman'"> <span style="FONT-SIZE: 11pt; FONT-FAMILY: Arial; mso-bidi-font-size: 10.0pt; mso-bidi-font-family: 'Times New Roman'">Students should be provided with opportunities to develop a better understanding of the need to provide a balance between the electrical energy needs of people and limited resources available to produce that energy. The importance of research into renewable, low impact sources of energy should be raised. They should also appreciate the imbalance that occurs across and between societies in the availability and consumption of electrical energy. <span style="FONT-SIZE: 11pt; FONT-FAMILY: Arial; mso-bidi-font-size: 10.0pt; mso-bidi-font-family: 'Times New Roman'"> <span style="FONT-SIZE: 11pt; FONT-FAMILY: Arial; mso-bidi-font-size: 10.0pt; mso-bidi-font-family: 'Times New Roman'">Open class discussions centred round Gospel values should challenge the students to formulate their own opinions about equity, conservation and respect for the opinions of others.
