Content
Physical World
Describing and exploring specific forces
Students:
- explore and describe some common contact or non-contact forces, for example:
− tension and elastic force
- perform a scientific investigation to explore the effects of changing the strength of a single contact or non-contact force, for example: SciT
− how a stronger or weaker applied force results in objects travelling longer or shorter distances
Transfer and transformation of energy
Students:
- identify different types of energy transformations, for example: (ACSSU097)
− heat energy to light energy
- investigate how electrical energy can be transferred and transformed in electrical circuits and can be generated from a range of sources (ACSSU097) SciT SysT
Forces and energy in products and systems
Students:
- describe examples where light, sound, heat and electrical energy transform from one type of energy to another, for example: ComT SysT
− a solar panel transforms light energy into electrical energy
- investigate how electrical energy can control movement, sound, or light in a product or system (ACTDEK020) ComT SciT
- design, test and evaluate a product or system that involves an energy transformation to meet an identified need using electrical energy ComT DesT
Material World
Properties of materials determine their use
Students:
- critique needs or opportunities for designing using sustainable materials DesT
- design a sustainable product, system or environment individually and/or collaboratively considering the properties of materials SysT DesT
- select appropriate materials, components, tools, equipment and techniques and apply safe procedures to produce designed solutions DesT
