The Cambridge IGCSE Chemistry 0620 syllabus provides a comprehensive foundation in chemistry for students aged 14-16, preparing them for further study and practical application.

Aims:

• Develop scientific knowledge and understanding of 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 scientific knowledge on people and the environment.

• Foster enjoyment and informed interest in science.

Key Content Areas:

• States of matter

• Atoms, elements, and compounds

• Stoichiometry

• Electrochemistry

• Chemical energetics

• Chemical reactions

• Acids, bases, and salts

• The Periodic Table

• Metals

• Chemistry of the environment

• Organic chemistry

• Experimental techniques and chemical analysis

Assessment Structure:

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

• Practical assessment through either a practical test or an alternative to practical paper.

• Assessment objectives:

  • Knowledge with understanding (50%)

  • Handling information and problem-solving (30%)

  • Experimental skills and investigations (20%)

Skills Developed:

• Observation, analysis, and safe laboratory practice.

• Application of scientific concepts to unfamiliar contexts.

• Interpretation and evaluation of data, including graphical and numerical information.

• Planning and conducting experiments, making and testing hypotheses.

Sample Key Concepts:

• Structure of the atom: nucleus with protons and neutrons, electrons in shells.

• Relative atomic mass (Arel), proton number (Z), and nucleon number (A).

• Isotopes: atoms of the same element with different numbers of neutrons.

• Ionic and covalent bonding, properties of ionic and covalent compounds.

• Giant covalent structures (e.g., diamond, graphite) and their properties.

Practical Skills:

• Safe use of laboratory apparatus and chemicals.

• Recording and interpreting experimental results.

• Evaluating methods and suggesting improvements.

The syllabus encourages learners to be confident, responsible, reflective, innovative, and engaged in scientific inquiry and problem-solving.
