SS2 Chemistry Scheme of Work (1st, 2nd, 3rd terms)

The Senior Secondary school two, SS2 Chemistry Scheme of Work takes students through structured learning of various chemistry topics in three terms.

It begins with atomic structure, periodic trends, chemical kinetics, and equilibrium in the first term, followed by electrochemistry and organic chemistry in the second term. In the third term, It delves into coordination chemistry, thermodynamics, metallurgy, and environmental chemistry.

Each week focuses on specific themes, including reactions, properties, and practical applications, ultimately enhancing students' understanding of fundamental chemistry concepts.
