  • Enzymes: Understanding enzymes is crucial to biology. Students learn about enzyme action, factors affecting enzyme activity, and the role enzymes play in metabolic pathways.
  • Plant Nutrition: This topic explores how plants obtain nutrients, including the process of photosynthesis and its importance for life on Earth.
  • Human Nutrition: Students examine the components of a balanced diet, the digestive system’s structure and function, and how nutrients are absorbed and utilised by the body.
  • Transport in Plants: This section covers the mechanisms plants use to transport water, minerals, and sugars, including the structure and function of xylem and phloem.
  • Transport in Animals: Students learn about the circulatory system in humans and other animals, including the heart’s structure and function, blood vessels, and the transport of gases, nutrients, and waste products.
  • Diseases and Immunity: This important topic covers the causes and prevention of diseases, the body’s defence mechanisms against pathogens, and the principles of vaccination and immunity.
  • Gas Exchange in Humans: Students explore the respiratory system, the process of gas exchange in the lungs, and how breathing is regulated.
  • Respiration: This topic delves into the biochemical pathways of respiration, the role of ATP in energy transfer, and the differences between aerobic and anaerobic respiration.
  • Excretion in Humans: The focus here is on the removal of metabolic waste from the body, including the structure and function of the excretory system, particularly the kidneys.
  • Coordination and Response: Students investigate how organisms respond to changes in their environment, covering the nervous and endocrine systems, receptors, and effectors.
  • Drugs: This topic addresses the effects of drugs on the body, including medical drugs and drugs of abuse, their modes of action, and societal issues related to drug use.
  • Reproduction: Students learn about sexual and asexual reproduction in plants and animals, including human reproductive systems, the menstrual cycle, and the development of gametes.
  • Inheritance: This area explores the principles of genetics, including Mendel’s laws, the inheritance of characteristics, genetic diagrams, and the concept of variation.
  • Variation and Selection: Students examine the sources of genetic variation, the process of natural selection, and how these principles contribute to the evolution of species.
  • Organisms and Their Environment: This topic focuses on ecology, studying how organisms interact with each other and their environment, including food webs, energy transfer, and cycles of matter.
  • Biotechnology and Genetic Engineering: Students explore the applications of biotechnology, including genetic modification, cloning, and the ethical considerations associated with these technologies.
  • Human Influences on Ecosystems: The course concludes with a look at the impact humans have on the environment, including pollution, habitat destruction, and conservation efforts to protect biodiversity.

Each topic is designed to build on the previous ones, providing students with a layered understanding of biology. Through interactive lessons, practical activities, and continuous assessment, students develop not only theoretical knowledge but also critical thinking and problem-solving skills, essential for success in further education and careers in biology and related fields.

Homework, Assessment, and Reporting

Homework is a pivotal component of the CHSO IGCSE Biology course, with assignments allocated fortnightly for Level 3 students and weekly for Level 4. Regular assessments, including internal exams and mock tests, provide valuable feedback on student progress, while detailed reports offer insights into attainment and effort across subjects.

Practical Work and Experiments

Despite the online nature of the course, CHSO encourages an interactive and hands-on approach to learning biology. While practical experiments are not conducted during live sessions, students are urged to engage in safe, supervised experiments at home to complement their theoretical knowledge.

Examination Preparation

Success in IGCSE Biology requires not only understanding the subject matter but also effective examination preparation. CHSO provides comprehensive support to students in this regard, emphasising the importance of:

  • Revision Strategies: Developing effective revision techniques, such as creating revision cards and topic-specific notes, is crucial. CHSO encourages students to review their notes regularly to reinforce their learning.
  • Exam Technique: Understanding the format of the exam and practising past papers helps students become familiar with the types of questions they might encounter, improving their time management and answering skills.

Parents play a vital role in arranging their child’s examinations at a local registered examination centre. CHSO assists families in this process, ensuring that each student finds a suitable venue to sit their written and practical exams.

Book List and Stationery

To maximise the learning experience, CHSO recommends specific resources:

  • Recommended Textbook: “Complete Biology for IGCSE” by Ron Pickering, endorsed by the University of Cambridge International Examinations, is an invaluable resource for students. This comprehensive guide aligns closely with the syllabus and enhances the learning process.
  • Essential Stationery: Access to basic stationery, such as pencils, pens, a ruler, an eraser, and a notebook, is essential. Additionally, having access to a printer is beneficial for printing course materials and revision aids.

Parent and Student Support

CHSO believes in the power of collaborative education, where parents, students, and teachers work together to achieve academic success. The unique approach includes:

  • Continuous Dialogue: Through the family Teams account, parents can maintain an ongoing conversation with teachers, enabling them to track their child’s progress closely.
  • Success Coaches and Reports: Regular reports and feedback from success coaches and the Head Teacher provide insights into students’ achievements and areas for improvement, fostering a supportive learning environment.

Safety Disclaimer and Responsible Experimentation

Safety is paramount when conducting experiments. CHSO emphasises that:

  • Supervised Experiments: Any practical work undertaken at home should be supervised by an adult to ensure safety. CHSO provides guidelines but leaves the decision to conduct experiments to parents and students, who must accept responsibility for any outcomes.
  • Digital Resources: For those unable to conduct experiments at home, CHSO recommends utilising digital resources, such as instructional videos on platforms like YouTube, to observe practical demonstrations.
