Week Lesson Strand Sub-strand Lesson Learning Outcomes Learning Experiences Key Inquiry Question(s) Learning Resources Assessment Reflection
3 1 Physical Chemistry 2.1 Acids and Bases By the end of the lesson, the learner should be able to:
a) carry out titration experiments;
b> determine concentration of acids;
c> appreciate quantitative analysis.		 The learners will be guided to:
i> set up burette and pipette;
ii> perform acid-base titration;
iii> calculate concentration (Core competency: Precision; PCI: Environmental issues - safety in the laboratory).		 How do we find the concentration of an acid? Burette, pipette, acids, bases Titration report assessed using a precision and safety rubric —
3 2 Physical Chemistry 2.1 Acids and Bases By the end of the lesson, the learner should be able to:
a) carry out titration experiments;
b> plot titration curves;
c> appreciate endpoint detection.		 The learners will be guided to:
i> repeat titration with pH meter;
ii> plot pH vs. volume;
iii> identify equivalence point (Core competency: Data analysis; PCI: Environmental issues - safety in the laboratory).		 What does a titration curve tell us? pH meter, graph paper Graph interpretation assessed using a data analysis and safety rubric —
3 3 Physical Chemistry 2.1 Acids and Bases By the end of the lesson, the learner should be able to:
a) investigate household acids and bases;
b> test vinegar, baking soda;
c> appreciate kitchen chemistry.		 The learners will be guided to:
i> test household substances;
ii> create pH scale of home items;
iii> discuss safety (Core competency: Responsibility; PCI: Socio-Economic and Environmental issues - consumer protection).		 What household items are acidic? Household substances, indicators Home pH chart assessed using a responsibility and consumer protection rubric —
3 4 Physical Chemistry 2.1 Acids and Bases By the end of the lesson, the learner should be able to:
a) research industrial acid production;
b> present on contact process;
c> appreciate scale chemistry.		 The learners will be guided to:
i> research contact process for H2SO4;
ii> create flow chart;
iii> discuss economic impact (Core competency: Digital literacy; PCI: Socio-Economic and Environmental issues - consumer protection).		 How is sulphuric acid made industrially? Internet, flow chart tools Flow chart assessed using a digital literacy and consumer protection rubric —
3 5 Physical Chemistry 2.1 Acids and Bases By the end of the lesson, the learner should be able to:
a) model acid dissociation;
b> use molecular kits;
c> appreciate particle representation.		 The learners will be guided to:
i> model HCl dissociation with kits;
ii> show H+ and Cl- ions;
iii> compare with weak acids (Core competency: Creativity; PCI: Environmental issues - safety in the laboratory).		 How do strong and weak acids differ at particle level? Molecular model kits Model assessed using a creativity and safety rubric —
