Content descriptor classify different types of energy as kinetic or potential and investigate energy transfer and transformations in simple systems

Elaborations

• • Elaboration investigating relationships between kinetic and potential energy in a simple system such as a roller-coaster or Newton’s cradle
• • Elaboration classifying types of energy as either kinetic energy such as movement, heat and electricity or potential energy such as chemical, elastic and gravitational
• • Elaboration critiquing and using representations such as flow diagrams to illustrate changes between different forms of energy in a system
• • Elaboration identifying where heat energy is produced as a by-product of energy transfer, such as filament light globes, exercise, and battery charging and use
• • Elaboration using electrical circuits and components to demonstrate electrical energy transfer and its transformation into heat, light and sound
• • Elaboration observing a Rube Goldberg machine and identifying the energy transfers and transformations involved
• • Elaboration investigating traditional fire-starting methods used by First Nations Australians and their understandings of the transformation of energy
