Year 10 Biological Science Program Semester 2 2015

Year 10 Level Description
The Science Inquiry Skills and 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 Standard 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 should be 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.
In the Year 10 curriculum students explore systems at different scales and connect microscopic and macroscopic properties to explain phenomena. Students explore the
biological, chemical, geological and physical evidence for different theories, such as the theories of natural selection and the Big Bang. Atomic theory is developed to
understand relationships within the periodic table. Understanding motion and forces are related by applying physical laws. Relationships between aspects of the living,
Year 10 Content Description
Science Understanding
Biological sciences
Science as a Human Endeavour
Nature and development of science
The transmission of heritable characteristics from
one generation to the next involves DNA and genes
Scientific understanding, including models and
theories, are contestable and are refined over time
through a process of review by the scientific
community (ACSHE191)
The theory of evolution by natural selection
explains the diversity of living things and is
supported by a range of scientific evidence
Advances in scientific understanding often rely on
developments in technology and technological
advances are often linked to scientific discoveries
Use and influence of science
People can use scientific knowledge to evaluate
whether they should accept claims, explanations or
predictions (ACSHE194)
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
Science Inquiry Skills
Questioning and predicting
Formulate questions or hypotheses that can be
investigated scientifically (ACSIS198)
Processing and analysing data and
Analyse patterns and trends in data, including
describing relationships between variables and
identifying inconsistencies (ACSIS203)
and describe specific ways to improve the quality
of the data (ACSIS205)
Critically analyse the validity of information in
secondary sources and evaluate the approaches
used to solve problems (ACSIS206)
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 (ACSIS199)
Use knowledge of scientific concepts to draw
conclusions that are consistent with evidence
Select and use appropriate equipment, including
digital technologies, to systematically and
accurately collect and record data (ACSIS200)
Evaluate conclusions, including identifying sources
of uncertainty and possible alternative explanations,
Communicate scientific ideas and information for a
particular purpose, including constructing evidencebased arguments and using appropriate scientific
language, conventions and representations
1. Outline processes involved in natural selection and describe biodiversity as a function of evolution.
2. Investigate the changes caused by natural selection in a population and describe the relationship between genetic characteristics,
survival and reproduction.
3. Evaluate and interpret evidence for evolution (including, fossil records, chemical and anatomical similarities and geographical
4. Discuss the role of different sources of evidence for evolution by natural selection, including biochemical, anatomical and fossil
Revision quiz testing the knowledge retained from
semester 1.
Fossils and evolution
Examine the evolution of the horse. Find
fossil evidence from the chapter to
support the idea that the horse had
evolved over time.
Define: evolution and generation.

Structure and relationships
Theory – That organisms that exhibited the same
characteristic must be related at some point. Relate
this back to their study of genetics in semester 1.
Matching activity – using different organisms to
illustrate similarities between species.
Analogous &amp; homologous structures – Identify
if features on an organism is analogous or
homologous. A continuation of the above activity.
Why do we breed different animals and plants?
What do humans try to achieve from this?
Artificial selection – process by which we choose
to breed organisms by desirable features/functions.
Students choose a particular organism (birds, dogs,
cats, flowers etc.) and look at what feature has
been bred in/out, why and compare. Create a fact
Darwin &amp; Natural Selection
Examine Darwin’s theory of natural selection.
Students define natural selection and explain how
the desired features are ‘chosen’ and passed onto
the next generation. Define selective agent &amp;

introduce the idea of ‘survival of the fittest’ – only
those characteristics that will help the organism to
survive are more likely to be passed on.
Variation – Natural selection can only act if
variation is involved (Darwin’s theory). Students
must use prior knowledge about genes to explain
how variation in characteristics can be passed on.
Complete experiment.
Students brainstorm the variation evident in
humans (height, nose shape, skin colour etc.)
Variation task: present students with pictures of
plants of the same type (species). Examine a
particular feature (leaf size, structure, colour) and
examine the variation between them.

Humans and apes
Briefly compare structures between humans and
apes. Students create a brief timeline/scale/flow
chart of human evolution using information from
the text. Students must examine the evidence and

brief description should be included. Students
should also b aware that these groups may have
evolved at the same time, rather than one at a time.
