Biology Form 1 under the Zambia CBC framework focuses on the study of living organisms, cell structure, plant and animal biology, and ecosystems. Learners develop competence-based skills in observation, experimentation, and analytical thinking. The syllabus aligns with ECZ assessment standards, and learners practice past exam questions, practical exercises, and revision activities. 25schools provides interactive materials and structured guidance to help learners consolidate knowledge, strengthen scientific reasoning, and prepare effectively for national examinations and higher Forms.

Topic 18
Nutritional Deficiency Diseases and Disorders
Students learn about diseases caused by a lack of specific nutrients, such as kwashiorkor, marasmus, scurvy, rickets, and goitre. This topic links diet directly to health outcomes, a key area in human biology for ECZ exams. It raises awareness among Zambian learners about preventable health conditions and the importance of a balanced diet, supporting the syllabus's integration of biology with life skills and health education.

Topic 23
Coordination and Response in Animals
Students explore taxic responses (directional movement) in invertebrates, such as phototaxis in cockroaches and chemotaxis in bacteria. They evaluate the relevance of these responses and apply the knowledge to pest control. This topic introduces the concept of animal behaviour as a biological response. It is foundational for later study of the nervous and endocrine systems and is relevant to ECZ questions on animal biology and practical applications in agriculture and health.

Biotic and Abiotic Interactions
This topic teaches students to distinguish between biotic (living) and abiotic (non-living) factors in an ecosystem and analyse the three kinds of relationships: within the biotic community, between the biotic community and the physical environment, and within the physical environment itself. Understanding these interactions is fundamental to ecology and is heavily tested in ECZ exams. It helps Zambian learners see the complex web of connections in their local environment.

Topic 8
Characteristics of Living Things
This topic covers the seven key characteristics of living things: feeding/nutrition, respiration, excretion, reproduction, sensitivity/irritability, movement/locomotion, and growth. Students will analyse these characteristics to distinguish living from non-living things and categorise life processes into catabolism and anabolism. Understanding these features is essential for defining life and forms the basis for many ECZ exam questions. It equips Zambian learners with the foundational knowledge needed to explore more complex biological processes in subsequent forms.

Ecological Relationships and Evolution
This unit introduces learners to basic ecology and environmental science. Students will explore local ecosystems, interpret biotic and abiotic interactions, practice waste management, and analyse soil composition and fertility. These topics ground biological study in the Zambian environment and address cross-cutting issues like climate change and sustainability. This knowledge is crucial for ECZ exams on ecology and aligns with the CBC's goal of creating environmentally responsible citizens.

Reproduction in Living Organisms
This topic introduces learners to the concept of reproduction as a life process. Students demonstrate an understanding of how different types of organisms reproduce, setting the stage for detailed study of reproduction in plants, humans, and microorganisms in later forms. It is a fundamental concept for ECZ exams, as questions on reproduction and continuity of life are common. It helps Zambian students grasp the biological imperative for species survival.

Reproduction and Development in Human Beings
Students learn about the human reproductive system, drawing and labeling male and female structures, explaining their functions, and outlining secondary sexual characteristics. They also practice personal hygiene. This topic provides essential knowledge for Zambian learners' personal development and health education. It is a sensitive but crucial part of the ECZ syllabus, assessed in questions on human biology and life skills, and aligns with the CBC's focus on holistic education.

Reproduction in Viruses, Protozoa, Bacteria and Fungi
Learners explore the diverse methods of reproduction in microorganisms: viral replication, binary fission in protozoa and bacteria, and spore formation in fungi. They investigate fungal structure by growing cultures. This topic introduces the invisible world of microbes, which is vital for understanding disease, decomposition, and biotechnology. It prepares Zambian students for ECZ questions on microbiology and its applications in health and the environment.

Coordination and Response in Plants
This topic introduces tropisms—directional growth responses in plants to stimuli like light (phototropism) and gravity (geotropism). Students explore the relevance of these responses to plant survival. Understanding how plants interact with their environment is a basic principle of biology assessed in ECZ exams. It helps Zambian learners appreciate that even stationary organisms like plants sense and respond to their surroundings, a concept that will be expanded with plant hormones in Form 2.
