How do scientists develop life-saving medicines? What makes batteries power electric vehicles? And how can chemistry help solve challenges such as climate change, clean water shortages and sustainable energy production?
Chemistry ATAR explores the composition, structure and behaviour of matter and investigates the chemical processes that shape the world around us. From the food we eat and the materials we use to medical breakthroughs and environmental solutions, chemistry plays a vital role in modern life and future innovation.
Through practical investigations, problem-solving and scientific inquiry, students develop analytical thinking, mathematical reasoning and laboratory skills while learning how chemistry contributes to ethical decision-making, sustainability and service to the wider community.
Why do different substances behave in different ways? How can chemists predict chemical reactions? And what happens at an atomic level when matter changes?
In Unit 1, students investigate atomic structure, chemical bonding and the properties of substances. They explore how the arrangement of atoms influences the behaviour of elements and compounds and examine how chemical reactions involve the transfer and transformation of energy.
Students apply the mole concept to solve quantitative problems and investigate how chemistry is used to design useful materials, improve industrial processes and develop products used in medicine, agriculture and manufacturing. Through laboratory experiments and data analysis, students develop practical skills in scientific investigation and chemical problem-solving.
Why does soft drink lose its fizz? How do antacids relieve heartburn? And why do some chemical reactions happen instantly while others occur slowly over time?
In Unit 2, students investigate the physical and chemical properties of materials, with a focus on gases, water, aqueous solutions, acids and bases. They explore why water is essential for life, how substances dissolve, and how solutions can be tested, compared and analysed in everyday and industrial contexts.
Students also examine reaction rates and investigate how factors such as temperature, concentration, surface area and catalysts affect the speed of chemical reactions. Using models such as Kinetic Theory and particle theory, students develop an understanding of how and why chemical reactions occur.
Through practical and research investigations, students develop skills in measuring reaction rates, analysing gases and solutions, predicting reaction outcomes and applying scientific knowledge to real-world situations in areas such as health, industry and environmental science.
