Science Australia 4 Year 10 students round off their studies of ideas and skills in general science. They apply their understanding of physics to sport. Their understanding of chemistry and biology is used in a forensic science exploration. Topics include motion in sport, evolution, chemical reactions, biochemistry, sound and light technology, homeostasis and forensic science. Using a wide variety of sports as the context student investigate the concepts of mass and weight, force, friction, aerodynamics, work, energy, momentum and inertia.
Students look at examples all the forms of electromagnetic radiation.
They explore the origin of the radiation, how it may be used and any potential dangers. The reflection and refraction of light are investigated in detail. Oxidation is used as the starting point for developing the skills of writing chemical formulae and balanced equations. Ionic bonding is revised and covalent bonding is introduced. Isotopes, allotropes, carbon compounds and electrolysis are introduced as patterns related to atomic structure, bonding and chemical reactions.
