SS2 Chemistry 1st Term
SS2 Chemistry First Term Scheme of Work & Lesson Note
Chemistry is one of the science subjects SS2 students are required to offer in first term. The Unit of Instruction for SS2 Chemistry 1st Term is carefully developed from the Scheme of Work, which in turn is, based on NERDC current curriculum and SSCE syllabus.
Mass-Volume Relationship, Acid–Base Titration, Chemical Reactions, Energy and Chemical Reactions, Chemical Equilibrium, Water, Solution and Solubility, ETC
