Week Lesson Strand Sub-strand Lesson Learning Outcomes Learning Experiences Key Inquiry Question(s) Learning Resources Assessment Reflection
2 1 Cell Biology and Biodiversity 1.2 Specimen Collection and Preservation By the end of the lesson, the learner should be able to:
a) improvise apparatus from locally available materials;
b) build a pooter or sweep net;
c) appreciate resourcefulness in science.		 The learners will be guided to:
i) improvise apparatus from locally available materials;
ii) test functionality in pairs;
iii) discuss environmental impact (Core competency: Critical Thinking and Problem Solving; PCI: Environmental conservation).		 How can we improvise specimen collection tools? Local materials (bottles, nets, tubes) Tool functionality assessed using a critical thinking and conservation rubric —
2 2 Cell Biology and Biodiversity 1.2 Specimen Collection and Preservation By the end of the lesson, the learner should be able to:
a) collect, process and preserve specimens using improvised apparatus;
b) follow ethical collection practices;
c) appreciate biodiversity conservation.		 The learners will be guided to:
i) observe designated road crossing points while collecting specimen;
ii) collect plant specimens ethically;
iii) press samples for herbarium (Core competency: Self-efficacy; PCI: Environmental conservation).		 How do we collect specimens responsibly? Collection tools, field site Specimen collection assessed using a self-efficacy and conservation checklist —
2 3 Cell Biology and Biodiversity 1.2 Specimen Collection and Preservation By the end of the lesson, the learner should be able to:
