The Scottish Higher Chemistry: Reactions, Bonding & Energy Changes course offers an in-depth exploration of key chemical principles that shape our understanding of matter and energy. Aligned with the Scottish Qualifications Authority (SQA) Higher Chemistry curriculum, this course provides a comprehensive learning experience that prepares students for academic success and scientific literacy.

The course begins with a close examination of chemical reactions and the factors that influence their speed and direction. Students learn about collision theory, activation energy, and how variables such as temperature, concentration, and catalysts affect reaction rates. Practical activities and real-world examples help contextualise theoretical knowledge, while students also explore reversible reactions and chemical equilibrium—essential concepts in both academic chemistry and industrial applications.

In the second module, learners dive into the nature of chemical bonding and the structures that result from atomic interactions. Lessons cover ionic, covalent, and metallic bonding, as well as intermolecular forces, periodic trends, and how these factors determine the physical properties of substances. Through the study of bonding in everyday materials, students gain insight into how chemistry underpins technologies and products used in modern life.

The final section of the course focuses on energy changes in chemical processes. Students explore the distinction between exothermic and endothermic reactions, learn how to calculate enthalpy changes, and use calorimetry techniques to measure energy transfer. Additional lessons on fuels, energy efficiency, and sustainability promote awareness of how chemistry contributes to global energy solutions and environmental responsibility.

Each lecture includes guided revision, assessment tasks, and practical applications to reinforce learning and prepare students for the SQA exam. With a focus on scientific inquiry, problem solving, and real-life relevance, this course supports learners in developing both theoretical understanding and practical competence in chemistry.
