Chemistry
Chemistry is a dynamic and fascinating science that explores the composition, structure, properties, and changes of matter. The Preliminary and HSC Chemistry courses provide students with a comprehensive understanding of chemical principles and their applications in everyday life and various scientific fields.
Preliminary Chemistry (Year 11)
Course Structure:
The Preliminary Chemistry course is designed to introduce students to fundamental concepts in chemistry and prepare them for the more advanced topics in the HSC course. The course typically covers the following core topics:
Properties and Structure of Matter:
Understanding atoms, molecules, and compounds
The periodic table and trends in properties
Intermolecular forces and their effects on properties
Chemical Reactions:
Types of chemical reactions (synthesis, decomposition, combustion, etc.)
Balancing chemical equations
The concept of the mole and stoichiometry
Quantitative Chemistry:
Measuring and calculating concentrations
Understanding molarity and molality
Empirical and molecular formulas
Energy Changes in Chemical Reactions:
Endothermic and exothermic reactions
Understanding reaction rates and factors affecting them
The Nature of Acids and Bases:
Properties of acids and bases
pH scale and its significance
Neutralisation reactions
Practical Work:
Practical experiments are a significant component of the Preliminary Chemistry course. Students engage in hands-on activities to reinforce theoretical concepts, develop laboratory skills, and understand safety procedures.
HSC Chemistry (Year 12)
Course Structure:
The HSC Chemistry course builds on the concepts learned in the Preliminary course and delves deeper into advanced chemical theories and applications. The course is divided into core and optional topics:
Core Topics:
Managing Chemical Processes:
Industrial processes and their environmental impact
Principles of green chemistry
Chemical Fundamentals:
The nature of chemical bonding
Advanced stoichiometry and equilibrium concepts
Chemical Equilibrium:
Le Chatelier's principle
Factors affecting equilibrium and applications
Organic Chemistry:
Structure and naming of organic compounds
Functional groups and their reactions
Energy and the Environment:
Energy transformations and conservation
The role of chemistry in addressing environmental challenges
Optional Topics:
Students may select from various optional topics such as:
The Chemistry of Food
Industrial Chemistry
Chemistry and Art
Practical Work:
Practical work in the HSC Chemistry course is designed to develop students' investigative skills and understanding of scientific methods. Students conduct experiments, analyse results, and draw conclusions based on their findings.
Assessment and Examination
Assessment:
Both the Preliminary and HSC Chemistry courses involve a combination of school-based assessments, such as practical reports, written tests, and projects. These assessments are designed to evaluate students' understanding and application of chemistry concepts.
HSC Examination:
At the end of Year 12, students will sit for the HSC Chemistry examination, which assesses their knowledge and understanding of the entire HSC curriculum. The examination typically includes a mix of multiple-choice, short answer, and extended response questions.
Conclusion
Studying Chemistry at the Preliminary and HSC levels equips students with essential scientific knowledge and skills applicable in various fields, including medicine, engineering, environmental science, and research. It fosters critical thinking, problem-solving, and analytical skills, preparing students for further studies and careers in science and technology.
