2026 Grade 10 Chemistry Lesson Plans – Week 1-Week 14 – Term 2

It covers the following strands and sub-strands:

• Inorganic Chemistry
  • Periodicity
    • Periodic trends in physical properties, atomic size and radius, ionisation energy, electronegativity, electron affinity, trends in melting and boiling points, physical and chemical properties of Group I (Alkali metals) including reactions with water, properties of Group II (Alkaline earth metals), and properties/reactions of Group VII (Halogens).
• Physical Chemistry
  • Acids and Bases
    • Arrhenius definitions, household acids and bases, the pH scale and its importance in agriculture and aquatic life, industrial uses of common acids (sulfuric, nitric) and bases, and the use of indicators for testing strength.
  • Introduction to Salts
    • Definition and nomenclature of salts, solubility rules, laboratory preparation methods for soluble and insoluble salts, writing and balancing chemical and net ionic equations, crystallization and saturated solutions, environmental impacts of excessive salt use (eutrophication/salinity), and qualitative analysis (ion identification via precipitates).
