Sierra Leone JSS3 Integrated Science Syllabus This syllabus covers a wide range of science subjects, including physics, chemistry, biology, agricultural science, earth science, home economics, and mathematics. The teaching approach emphasizes demonstrations, problem-solving, analysis, experiments, and fieldwork. The syllabus is divided into thirty units, serving as a guide for problem-solving, demonstrations, group work, and continuous assessment. The Basic Education Certificate Examination (BECE) for Integrated Science consists of three sections:
The syllabus content is organized into units covering various topics. Unit 1 focuses on Force, Work, Power, and Energy, exploring concepts like types of forces, effects of force, friction, and calculations related to these concepts. Unit 2 covers Measurement, listing common physical quantities, appropriate instruments, and SI units. Unit 3 delves into Density, Weight, and Volume, explaining their measurement, differences between mass and weight, determining volume, and calculating density. Unit 4 explores Machines, including simple and complex machines, mechanical advantage, velocity ratio, and efficiency. Unit 5 discusses Heat and Sources of Heat, covering heat generation, effects of heat, and factors affecting heat change. Unit 6 focuses on Measurement of Heat, including heat capacity, specific heat capacity, and latent heat. Unit 7 covers Electricity, describing static and current electricity, circuit components, and primary/secondary cells. Unit 8 explores Matter, explaining its nature, states, characteristics, and changes in state. Unit 9 covers Separation of Mixtures, outlining methods like filtration, evaporation, distillation, and chromatography. Unit 10 focuses on Air, discussing its components, rusting, and properties/uses of gases in air. Unit 11 delves into Water, covering sources, uses, properties, treatment, and hardness. Unit 12 explores the Periodic Table, explaining its organization, groups, periods, and families of elements. Unit 13 focuses on Atomic Structure, distinguishing between atomic and mass numbers and describing particle arrangement. Unit 14 covers Chemical Formulae and Equations, explaining their writing and balancing. Unit 15 explores Acids, Bases, and Salts, explaining their properties, types, and neutralization. Unit 16 discusses Metals and Non-metals, classifying elements and describing their properties and alloys. Unit 17 focuses on Continuity and Change, differentiating between living and non-living things. Unit 18 explores Living Cells, describing their structure and functions in plants and animals. Unit 19 covers Amoeba Proteus, describing its structure, functions, and life processes. Unit 20 discusses Flowering Plants, describing their structure and functions. Unit 21 focuses on Flowers, covering their structure, pollination, fertilization, and fruit development. Units 22 and 23 explore Nutrition, classifying food items, explaining nutrient importance, and testing for starch, proteins, fats, and oils. Unit 24 covers Digestion in Humans, describing the digestive system's structure and function. Unit 25 explores the Circulatory System, describing its structure, functions of blood and heart, and types of circulation. Unit 26 focuses on Ecology, explaining basic ecological terms and defining ecosystems. Unit 27 discusses Ecosystems, describing component interactions and dependencies between plants and animals. Unit 28 covers Population Changes, defining population, migration, and related terms, listing factors affecting population, and discussing problems of population growth. Unit 29 delves into Earth Science, covering the universe, moon, eclipse, planets, and their characteristics. Unit 30 focuses on Soil and Rocks, describing earth's structure, rock formation, soil types, and soil conservation. [ |
