Singapore · MOE Syllabus Outcomes
Secondary 3 Science (Chemistry, Biology).
This curriculum provides Secondary 3 students with a strong foundation in biological concepts as part of the Singapore O-Level Science (Chemistry, Biology) syllabus. It emphasizes scientific inquiry, the understanding of living systems, and the application of biology to everyday life.
01Principles of Biology
Students explore the fundamental building blocks of life, including cell structure, the movement of substances, and biological molecules.
Students explore the basic building blocks of life by examining plant and animal cells. They learn to identify cellular organelles and understand their specific functions.
This topic investigates how substances move in and out of cells. Students will differentiate between diffusion, osmosis, and active transport.
Students learn about the chemical composition of living organisms, focusing on carbohydrates, fats, and proteins. They will also conduct food tests to identify these nutrients.
This topic introduces enzymes as biological catalysts. Students will explore the lock-and-key hypothesis and factors affecting enzyme activity.
02Maintenance of Life
This unit covers the essential processes that maintain life in plants and humans, including nutrition and transport systems.
Students examine the human digestive system and the processes of ingestion, digestion, absorption, and assimilation. The focus is on how complex food is broken down into simple, soluble substances.
This topic covers photosynthesis, the process by which plants synthesize food. Students will investigate the factors necessary for photosynthesis and the structure of a leaf.
Students learn about the transport systems in plants, specifically the xylem and phloem. They will explore the processes of transpiration and translocation.
This topic explores the human circulatory system, including the heart, blood vessels, and blood components. Students will understand how oxygen and nutrients are delivered to cells.
03Respiration and Coordination
Students investigate how organisms release energy through respiration and how they detect and respond to changes in their environment.
Students differentiate between aerobic and anaerobic respiration and understand their importance in energy release. They also study the human gas exchange system.
This topic introduces the human nervous system, focusing on the brain, spinal cord, and nerves. Students will learn about reflex actions and voluntary responses.
Students examine the structure and function of the human eye as a sensory organ. They will explore how the eye focuses on near and distant objects.
This topic covers the endocrine system and the role of hormones in chemical coordination. Students will focus on adrenaline and its effects on the body.
04Continuity of Life
This unit explores how life is perpetuated through reproduction in plants and humans, and introduces the principles of heredity and genetics.
Students explore asexual and sexual reproduction in flowering plants. They will examine flower structure, pollination, and fertilization.
This topic covers the human male and female reproductive systems and the menstrual cycle. Students will learn about fertilization, implantation, and the development of the fetus.
Students are introduced to the basics of genetics, including chromosomes, genes, and alleles. They will use genetic diagrams to solve problems involving monohybrid inheritance.
This topic delves into the structure of DNA and its role in protein synthesis. Students will understand how genes determine the characteristics of an organism.
