Course Curriculum

Cell Division – This topic delves into cellular reproduction, covering mitosis for asexual reproduction and meiosis for sexual reproduction. It explores their roles in maintaining genetic information across organisms, integrating theory with practical applications.
Plant Reproduction – This topic covers the reproductive structures and processes in flowering plants. Students learn about flower structures, pollination mechanisms, and the formation of seeds and fruits. An example activity could involve dissecting a flower and identifying its different parts to understand their roles in reproduction.
Human Reproduction – This topic explores reproduction in humans, including the male and female reproductive systems. Students learn about the processes of fertilization, embryo development, and pregnancy. An example activity could involve studying the stages of embryonic development using visual aids.
Molecular Genetics – This topic delves into the study of DNA structure and its role in protein synthesis. Students learn about the process of DNA replication, transcription, and translation. An example activity could involve modeling the steps of protein synthesis using paper cut-outs to understand the relationship between DNA and proteins.
Inheritance – This topic explores the principles of inheritance and variation in organisms. Students learn about chromosomes, genes, alleles, genotype, phenotype, and the factors influencing genetic variation. An example activity could involve analyzing family pedigrees to understand how traits are inherited and predicting the likelihood of specific traits in offspring.
Ecology – This topic explores the dynamics of ecosystems, emphasizing energy transfer and interdependence among organisms. It addresses human impacts on ecosystems and focuses on global warming.
Homeostasis, Coordination and Response – This topic deeply explores the mechanisms by which living organisms detect and respond to changes in their internal and external environments to maintain a stable internal milieu essential for life sustenance. Emphasis is placed on the criticality of homeostasis in ensuring the stability of human physiological processes like digestion, respiration, and substance transport. Specific focus is given to the necessity of maintaining consistent water potential in blood for efficient substance exchange.
Review of the Human body – This topic thoroughly explores how systems such as nutrition, transport, respiration, and excretion interact to sustain life. Students analyze how energy usage and macromolecular systems contribute to growth, reproduction, and maintaining internal equilibrium. Furthermore, it investigates disease dynamics, highlighting the impact of pathogens on bodily functions and the historical development of disease understanding.
