Biology (Grade VI)
Grade VI
Tk. 5,000
Tk. 4,500
Before 10 July
Overview
Discover how living things function—from microscopic cells to human systems.
The Grade VI Biology syllabus provides a foundational understanding of living organisms, from cellular processes to human body systems and ecological concepts. The chart below illustrates the key learning areas:
Identify cell structures in plants and animals and explain their functions- Understand diffusion, osmosis, and active transport in cells
- Explore enzyme action and the lock-and-key model of specificity
- Describe photosynthesis and how leaf adaptations support this process
- Trace the transport of water and ions in flowering plants
- Understand nutrition, digestion, teeth, and enzyme function in humans
- Explore human gas exchange, respiration, and how breathing occurs
- Investigate the circulatory system, structure of the heart, and functions of blood
- Classify living organisms using a binomial system and key physical features
- Understand how variation and inheritance pass traits through generations
- Interpret biological diagrams, experiments, and data with accuracy
- Build a systems view of how organisms grow, adapt, and maintain life

Assessment and Practice
Each topic is assessed through structured tests, and every few weeks are set aside for consolidation and applied problem-solving. The mid-year and final mock exams provide full syllabus review and question-based mastery. Students apply biological reasoning in varied contexts—from cells to ecosystems—building deep conceptual understanding and scientific communication.
Course Structure Overview
This structured plan guides students through the fundamentals of biology, from cell structure and function to human body systems, classification, and inheritance, supported by regular assessment and spiral revision.
