Laboratory dissections, physiological modelling, and circulatory biochemistry form the backbone of Grade 10 Biology in Term 3. The 10-page syllabus maps 41 lessons across 9 weeks, aligning strictly with the Anatomy and Physiology of Animals strand prescribed for senior secondary life sciences.
- Internal Transport: examining insect vascular structures, tracing the cardiac pumping cycle, dissecting a mammalian heart, detailing the blood clotting cascade, and calculating compatibility across ABO and Rhesus blood systems (weeks 1 to 3).
- Gaseous Exchange and Respiration: contrasting breathing surfaces in locusts, frogs, and birds with human lungs; building bell-jar and balloon respiratory models; analysing anaerobic lactic acid pathways; and calculating respiratory quotients using respirometer experiments (weeks 3 to 6).
- Laboratory Evaluation: formative mid-term testing in week 7, followed by practical specimen reviews, respiratory model grading, and chemical safety checks during weeks 8 and 9.
Practical setups throughout the term require dissection trays, blood photomicrographs, Y-tubes, timers, and respirometer apparatus to support experimental biology.
