Year 3 Chemistry Lesson Planners for SHS | NaCCA Aligned

Chemistry in Year 3 is heavy on physical chemistry before moving into organic topics closer to WASSCE. This planner follows that order week by week.

First Semester (Weeks 1-12)

• Acid-base equilibria: pH, pOH, pKa/pKb and buffer solutions.
• Salts and indicators: hydrolysis of salts and acid-base indicators.
• Redox chemistry: oxidation and reduction reactions and titrations.
• Titration technique: balancing redox reactions and identifying oxidising/reducing agents.

Second Semester (Weeks 13-24)

• Electrochemistry: electrochemical cells, electrode potentials and electrolysis.
• Corrosion: how metals corrode and how to prevent it.
• Transition elements: their properties and complexes, compared with main group elements.
• Organic chemistry: esters, fats and oils, and natural and synthetic polymers.

Editable Word/PDF, split by semester or bundled together.
