Chemistry – AS & A Level

AQA

Description of the Specification

At AS Level candidates are given a solid grounding in foundation chemistry. The syllabus introduces the chemical reactivity of atoms and molecules and provides an understanding of their structures. The development and use of the periodic table is explained. The introduction of Practical Skills Assignments (PSA) into the specification allows teachers to credit candidates for work done in routine class practicals. Assessment is linked to the work of the course.

At A2 Level the syllabus develops the concepts of physical chemistry introduced at AS. Candidates will study kinetics, equilibria, organic chemistry and spectroscopic techniques to determine the molecular formulae and structures of organic compounds. Candidates will continue to be assessed through PSA, gaining credit for work done in routine class practicals.

Type and Nature of Work Involved

• Understanding of chemical concepts and principals, and applying them to unfamiliar situations including industrial applications.
• Demonstrating critical awareness of the technological aspects of chemistry, and of the issues of a social, economic and environmental nature;
• Developing skills in the design of experiments and the handling of delicate equipment, and potentially hazardous chemicals.
• Interpretation of information from various sources e.g. graphs, equations, written prose.
