The Cambridge IGCSE Chemistry 0620 syllabus provides a comprehensive foundation in chemistry for students aged 14–16, covering both theoretical and practical aspects.

Aims:

• Develop scientific knowledge and understanding of chemical theories and practice.

• Build experimental skills, including handling variables and working safely.

• Use scientific data and evidence to solve problems and evaluate scientific methods.

• Communicate effectively using scientific terminology, notation, and conventions.

• Understand the impact of chemistry on people and the environment.

• Foster enjoyment and informed interest in science.

Assessment Structure:

• Core and Extended assessment options, with multiple-choice, theory, and practical components.

• Assessment objectives:

  • Knowledge with understanding (50%)

  • Handling information and problem-solving (30%)

  • Experimental skills and investigations (20%)

Key Content Areas:

Core Concepts Highlighted:

• Structure of atoms: nucleus (protons, neutrons) and electron shells.

• Relative atomic mass and isotopes. Relative atomic mass=∑(isotope mass × abundance)total abundance

• Types of bonding: ionic, covalent, and metallic; properties of substances based on bonding.

• States of matter and changes of state (melting, boiling, freezing, condensation).

• Periodic Table organization and trends.

• Experimental skills: observation, data analysis, drawing conclusions, and safety.

Skills Developed:

• Application of knowledge to new situations and problem-solving.

• Planning and conducting experiments, interpreting results, and evaluating methods.

• Effective communication using scientific language and conventions.

Assessment Emphasis:

• Recall and explanation of factual material.

• Application of principles to unfamiliar contexts.

• Analysis and evaluation of experimental data.
