Physics and Chemistry

Human exploration of the natural sciences dates back to around 3000 BC when disciplines like physics, chemistry, biology, geography, and astronomy were collectively referred to as "science". From the early invention of bronze to the later advancements in shipbuilding, automotive engineering, and aviation, physics has always been intertwined with humanity's quest to understand the natural world. However, it was not until the 18th century, with Antoine Lavoisier's pioneering studies on air components, that the distinct boundary between chemistry and physics began to emerge. Nonetheless, many scientific inquiries continue to straddle the realms of both disciplines, leading to the development of physical chemistry as a distinct field of study.

​

Physical chemistry forms part of the Irish high school curriculum, stemming from the foundational science subjects studied in junior high school. Students engaging with physical chemistry are expected to possess a solid understanding of both physics and chemistry, adeptly applying concepts from both disciplines in their studies.

​

Physical chemistry courses may not be universally available across all schools. In some instances, collaboration between physics and chemistry teachers may occur to deliver the physical chemistry curriculum, while in others, teachers may specialize in teaching this interdisciplinary subject. Course materials typically include textbooks from both physics and chemistry, with some schools opting for teacher-prepared presentations (PPT) as an alternative.

The Leaving Cert examination for Physical Chemistry evaluates students' comprehension, recall, and application of theoretical knowledge. Students must opt for the Higher Level examination. The exam consists of two sections, A and B, each carrying 200 marks, with a total of 400 points and a duration of 3 hours. Section A assesses physics knowledge, while Section B focuses on chemical knowledge. The final score is calculated as a percentage of the total marks. Unlike traditional science exams, there are no experimental components; instead, the assessment emphasizes theoretical understanding across both physics and chemistry domains. Despite the breadth of topics covered, physical chemistry does not necessitate an exceptionally deep understanding compared to standalone physics or chemistry exams. The exam format resembles that of national standardized tests.

When selecting courses, students opting for physical chemistry are unable to choose standalone physics or chemistry courses simultaneously. It's advisable to consider separate physics and chemistry courses for several reasons. Firstly, standalone courses offer practical laboratory experiences, enhancing engagement and interest. Secondly, physical chemistry demands a rigorous understanding of both physics and chemistry principles, necessitating strong scientific thinking skills. Lastly, physical chemistry courses may not be widely available, requiring students to be self-motivated and prepared for independent study if they wish to pursue this subject.
