Physical Sciences
Physics - to be delivered in Term 4
(10th October to 7th December:
8 teaching weeks with week 9
being the Exam week)
Energy appears in different forms including movement (kinetic energy), heat and potential energy, and causes change within systems (ACSSU155)
Elaborations
●
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

ACSSU155
Consider sources of energy
– non-renewable (fossil
fuels and nuclear) and
renewable (wave, wind,
tidal, geothermal,
hydroelectric, solar and
biomass). Links with SHE.
ACSSU155
Investigate 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
ACSSU155
Investigate different forms
of heat transfer –
conduction, convection and
radiation
ACSSU155: 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
Revise concepts from
weeks 1-8
Investigate why it is
important to develop
renewable energy
resources and how they
can ‘captured’ to make
useful types of energy,
especially electricity and
heat
Energy Makes things
happen
Heat Transfer
Hot Stuff
Use flow diagrams to

They represent and predict the
effects of unbalanced forces,
including Earth’s gravity, on motion.
They identify different forms of
energy and describe how energy
transfers and transformations
cause change in simple
systems.

Energy transfer through
different mediums can be
explained using wave and
particle models
They explain the concept
of energy conservation and
represent energy transfer
and transformation within
systems. They apply
relationships between
force, mass and
acceleration to predict
changes in the motion of
objects.
Science Understanding
Physical Sciences
Science as a Human
Endeavour
Nature and development
of Science
Scientific knowledge changes
as new evidence becomes
available, and some scientific
discoveries have significantly
changed people’s
understanding of the world
Science knowledge can
develop through collaboration
and connecting ideas across
the disciplines of science
Use and influence of
Science
Science and technology
contribute to finding solutions to
a range of
Contemporary issues; these
solutions may impact on other
areas of society and involve
ethical considerations
Refer to year 7
descriptors.
Scientific understanding,
including models and
theories, are contestable
and are refined over time
through a process of
review by the scientific
community
Advances in scientific
understanding often rely
on developments in
technology and
technological advances
are often linked to
scientific discoveries
People can use scientific
knowledge to evaluate
whether they should
Refer to year 9
descriptors.
Science understanding
influences the development of
practices in areas of human
activity such as industry,
agriculture and marine and
terrestrial resource
management
People use understanding and
skills from across the
disciplines of science in their
occupations
accept claims,
explanations or
predictions
Advances in science and
emerging sciences and
technologies can
significantly affect
people’s lives, including
generating new career
opportunities
The values and needs of
contemporary society can
influence the focus of
scientific research
