Physical Science Content Descriptions
Energy appears in different forms, including movement (kinetic energy), heat and potential energy, and energy transformations and
transfers cause change within systems (ACSSU155)
• recognising that kinetic energy is the energy possessed by moving bodies
• recognising that potential energy is stored energy, such as gravitational, chemical and elastic energy
• investigating different forms of energy in terms of the effects they cause, such as gravitational potential causing objects to fall
and heat energy transferred between materials that have a different temperature
• recognising that heat energy is often produced as a by-product of energy transfer, such as brakes on a car and light globes
• using flow diagrams to illustrate changes between different forms of energy

Content
General overview of types of energy –
link with forces
Scientific Investigation: Pendulum and
Length, while recognising the constant
interchange of gravitational potential
energy and kinetic energy
Activities

learning – energy and forces.
 ICT exercise – find appropriate
diagrams and label them to identify
where each energy type and force
is being demonstrated.

Unit 3.7:
Solar cells

Consider sources of energy loss and
how they can be reduced.
 Solutions to contemporary issues
that are found using science and
technology, may impact on other
areas of society and may involve
ethical considerations
 People use science understanding
and skills in their occupations and
these have influenced the
development of practices in areas of
human activity
Investigate use of solar power in
Australia.
