A complete revision and exam practice bundle covering the full **SB5 Health, Disease and the Development of Medicines** unit of the Pearson Edexcel GCSE Biology (9-1) Separate Science specification. This bundle brings together all 12 individual topic packs into one discounted resource, giving teachers and students everything they need to master this unit from first teaching through to final exam preparation. Each pack in this bundle has been built directly from the official Edexcel specification, teaching and learning materials, and mark schemes.

This bundle contains 12 complete topic packs: **SB5a Health and Disease**: Covers definitions of health and disease, the distinction between communicable and non-communicable diseases, the role of the immune system, and how disease can compromise immunity. **SB5b Non-Communicable Disease**: Covers examples of non-communicable diseases, malnutrition and diet, the link between alcohol and liver disease, and the local, national and global impact of alcohol-related liver disease. **SB5c Cardiovascular Disease**: Covers BMI and waist-to-hip ratio calculations, correlations between obesity and cardiovascular disease, smoking and cardiovascular disease, the role of diet and exercise, and comparison of treatment options. **SB5d Pathogens**: Covers diseases caused by bacteria, viruses, protists and fungi, and how signs and symptoms can be used to identify the causative pathogen. **SB5e Spreading Pathogens**: Covers routes of pathogen transmission including water, air, vectors, direct contact and body fluids, with specific named examples (cholera, tuberculosis, malaria, Ebola, Helicobacter), and prevention strategies. **SB5f Virus Life Cycles**: Covers virus structure, how viruses differ from cells, the lytic and lysogenic pathways, comparison of both pathways, and cross-sectional area calculations of viral cultures. **SB5g Plant Defences**: Covers physical and chemical plant defences against pests and pathogens, plant protective chemicals used in human medicine, and the principles and purpose of aseptic technique. **SB5h Plant Diseases (H)**: Covers identification of plant disease from visible symptoms, elimination of environmental causes, distribution analysis, and laboratory diagnosis of plant pathogens. **SB5i Physical and Chemical Barriers**: Covers physical barriers (skin, mucus, cilia) and chemical barriers (lysozymes, hydrochloric acid) in the human body, and prevention of STIs including Chlamydia and HIV. **SB5j The Immune System**: Covers antigens, antibody production, memory lymphocytes, the secondary immune response, how immunisation works, and evaluation of immunisation including herd immunity. **SB5k - Antibiotics**: Covers the definition and mechanism of antibiotics, why they are effective against bacteria but not other pathogens, and the stages of new medicine development and why each stage is needed. **SB5l - Monoclonal Antibodies (H)**: Covers the production of monoclonal antibodies via hybridoma cells, their use in pregnancy testing and disease diagnosis (blood clots and cancer), and advantages over conventional drug and radiotherapy treatments. Every pack in this bundle contains five files. A **Topic Mastery Sheet** (PDF) - a comprehensive reference covering the full specification for that subtopic. Each sheet includes full specification coverage with spec reference codes, all key definitions and mechanisms explained in depth, worked examples using actual Edexcel exam figures, comparison tables and process diagrams, common errors explicitly flagged with the correct exam language, and a stretch and challenge section for students targeting Grade 8-9. A **Student Exam Practice Sheet** (PDF and DOCX) - five to seven exam-style questions escalating from recall through to extended writing. Questions use correct Edexcel command words, include mark allocations, and are sized with appropriate answer space. The DOCX version allows teachers to adapt questions for their class. A **Teacher Answer Key** (PDF and DOCX) - a full tick-point mark scheme verified against the official Edexcel mark scheme. Each answer includes the exact wording required, examiner notes on what is and is not accepted, full working for all calculation questions, and level descriptors for any extended writing questions. All resources are designed for whole-class use in mixed ability settings. Higher tier content is clearly tagged throughout. Questions escalate from foundation recall to higher extended writing within every sheet, so every student is working towards excellence without anyone being left behind or held back. Suitable for end-of-topic revision lessons, independent study, homework, intervention sessions, exam preparation in Year 10 and Year 11, cover lessons, and as a take-home revision pack for students.
