Chapter Overview & SLOs
What is the Science of Biology? Chapter 1, "The Science of Biology," provides a comprehensive introduction to the study of life and the scientific processes used to understand living organisms. What are the major branches of biology? You will learn the definitions and significance of key branches including Physiology, Paleontology, Biotechnology, Morphology, Anatomy, Cytology, Genetics, and Ecology. How is biology related to other sciences? Explore interdisciplinary fields including Biophysics, Biochemistry, Biometry, Bioeconomics, and Computational Biology. What careers can you pursue with biology? Career paths include Medicine, Pharmacology, Fisheries, Agriculture, Forestry, Animal Husbandry, Horticulture, and Farming. What is the biological method? Study all steps: Observation, Hypothesis, Deduction, Experimentation, Conclusion, and Theory/Law. Learn to differentiate between qualitative observations and quantitative observations. How was malaria investigated? Case study featuring Laveran (discovered parasite), A.F.A. King (identified mosquito vector), and Ronald Ross (proved transmission). Human malaria: Anopheles mosquitoes. Bird malaria: Culex mosquitoes. These notes are strictly aligned with the Student Learning Outcomes (SLOs) for the FBISE 2026 annual examination.
