Aspects Covered

Student Outcomes	Text References	Elements of SACSA Framework
Examples of evidence include that the student:
investigate ways of converting various energy forms into more easily usable forms (electricity), and the efficiencies and ecological sustainability of such conversions	p 270-273	Energy Systems 5.3 and Interdependence (In)
use simple electrical circuits to investigate a range of energy transfers, and tests ideas	p 258, 263-264	Energy Systems 5.4
performs appropriate calculations using standard scientific formulae (P = E/t and P = VI)	p 264-269
explains the difference between AC and DC	p 256
demonstrates understanding of electrical power by using the equations P = E/t and P = VI	p 264-269 Wbk p 98 (Chall)
demonstrates how electricity can be generated by the relative motion of a magnet and a coil of wire	p 271
explains how a chain reaction can be controlled to generate heat in a nuclear power station	p 273
deduces Ohm's law by collecting data on the current and voltage in a circuit and drawing a best-line fit	p 263-264	KC3 Planning and Organising
rearranges simple formulas, eg if V = IR, then I = V/R	p 264-269 Wbk p 97 (Core)	KC5 Using Maths
