YEAR 9 EXTENSION SCIENCE
IMCC 2015: TERM 1
CHEMICAL SCIENCES
Year 9 Level Description
The Science Inquiry Skills and the Science as a Human Endeavour strands are described across a two-year band. In their planning, schools and teachers refer
to the expectations outlined in the Achievement Standards and also to the content of the Science Understanding strand for the relevant year level to ensure
that these two strands are addressed over the two-year period. The three strands of the curriculum are interrelated and their content is taught in an integrated
way. The order and detail in which the content descriptions are organised into teaching/learning programs are decisions to be made by the teacher.
Over Years 7 to 10, students develop their understanding of microscopic and atomic structures, how systems at a range of scales are shaped by flows of
energy and matter and interactions due to forces, and develop the ability to quantify changes and relative amounts. In Year 9, students consider the operation
of systems at a range of scales. They explore ways in which the human body as a system responds to its external environment and the interdependencies
between biotic and abiotic components of ecosystems. They are introduced to the notion of the atom as a system of protons, electrons and neutrons, and how
this system can change through nuclear decay. They learn that matter can be rearranged through chemical change and that these changes play an important
role in many systems. They are introduced to the concept of the conservation of matter and begin to develop a more sophisticated view of energy transfer.
They begin to apply their understanding of energy and forces to global systems such as continental movement.
Year 9 Content Descriptions
Science Understanding
Chemical sciences
All matter is made of atoms which are
composed of protons, neutrons and
electrons; natural radioactivity arises from
the decay of nuclei in atoms (ACSSU177)
Chemical reactions involve rearranging
atoms to form new substances; during a
chemical reaction mass is not created or
destroyed (ACSSU178)
Chemical reactions, including combustion
and the reactions of acids, are important in
both non-living and living systems and
involve energy transfer (ACSSU179)
Science as a Human Endeavour
Nature and development of science
Scientific understanding, including models
and theories, are contestable and are
refined over time through a process of
review by the scientific community
(ACSHE157)
Advances in scientific understanding often
rely on developments in technology and
technological advances are often linked to
scientific discoveries (ACSHE158)
Use and influence of science
People can use scientific knowledge to
evaluate whether they should accept
claims, explanations or predictions
(ACSHE160)
Advances in science and emerging
sciences and technologies can significantly
affect people’s lives, including generating
new career opportunities (ACSHE161)
The values and needs of contemporary
society can influence the focus of scientific
research (ACSHE228)
Science Inquiry Skills
Questioning and predicting
Formulate questions or hypotheses that can
be investigated scientifically (ACSIS164)
Planning and conducting
Plan, select and use appropriate
investigation methods, including field
work and laboratory experimentation, to
collect reliable data; assess risk and
address ethical issues associated with these
methods (ACSIS165)
Select and use appropriate equipment,
including digital technologies, to
systematically and accurately collect and
record data (ACSIS166)
Evaluating
Evaluate conclusions, including identifying
sources of uncertainty and possible
alternative explanations, and describe
specific ways to improve the quality of the
data (ACSIS171)
Critically analyse the validity of
information in secondary sources and
evaluate the approaches used to solve
problems (ACSIS172)
Processing and analysing data and information
Communicating
Analyse patterns and trends in data,
including describing relationships between
variables and identifying inconsistencies
(ACSIS169)
Use knowledge of scientific concepts to
draw conclusions that are consistent with
evidence (ACSIS170)
Communicate scientific ideas and
information for a particular purpose,
including constructing evidence-based
arguments and using appropriate scientific
language, conventions and representations
(ACSIS174)

Spontaneous Exothermic Reaction
Unlike the rest of the listed
experiments, you can use this one to
demonstrate how quickly and
vigorously exothermic reactions may
occur. Use 3 grams of potassium
magnate and use a spatula to make a
hollow in the middle of it. Then, pour
about 1 cubed centimetre of glycerol
in the hollow. After a few seconds,
the compound will begin to give off
steam and spontaneously burst into
flames, leaving a black, ashy residue
behind it. Be sure to conduct this
experiment on a heatproof mat.
