Biology is the branch of science which deals with the study of living organisms. The ICSE Class 8 Biology syllabus covers topics such as transport of food and minerals in plants, reproduction in plant and animals, ecosystems, and human body-endocrine, circulatory and nervous system. The syllabus is designed to help you understand the basic concepts and principles of biology, and to develop your skills of observation, experimentation, and analysis. The syllabus also aims to foster your curiosity and interest in the natural world, and to appreciate its diversity and interdependence.

• Learning Objectives:

  UNIT 1: Transport of food and minerals in plants

  UNIT 2: Reproduction in plants and animals

  UNIT 3: Ecosystems

  UNIT 4: Human Body: Endocrine, Circulatory, and Nervous System

  UNIT 5: Health and Hygiene

  UNIT 6: Food Production

• Course Outline:

   

  UNIT 1: Transport of food and minerals in plants

  • Diffusion – its definition;
  • Osmosis – its definition, examples, semi-permeable membrane; active transport; root pressure;
  • Transpiration – its definition, importance and the factors affecting transpiration.
  • Structure and the function of the Xylem and Phloem in detail;
  • Importance of minerals: macro and micro-nutrients; three deficiency diseases caused by the lack of these essential nutrients.

   

  UNIT 2: Reproduction in plants and animals

  Plants

  • Sexual reproduction in the Plants:
    • Binary fission, fragmentation, budding, spore formation, vegetative propagation, artificial propagation by the tissue culture (basic process along with the suitable example of each)
  • Sexual reproduction in the Plants:
  • Review of parts of a typical flower (its 4 whorls and their structure and functions)
  • Pollination: self and cross;
  • Agents of pollination: the three characteristics of plants pollinated by insects, wind and water (with examples). Characteristics of the flowers of each kind.
  • The fertilisation process, in brief, is represented by a flow chart.
  • Mention of artificial pollination.

  Animals

  1. Sexual reproduction in humans:
  2. Main organs of the male and female reproductive system

   

  UNIT 3: Ecosystems

  1. Understanding ecosystems: definition, the interaction between biotic and abiotic factors.
  2. Biotic components consist of producers, consumers and decomposers. Meaning of food chain. Food web and pyramid of numbers.
  3. Interdependence between organisms: symbiosis, parasitism and predation.
  4. A brief account of the abiotic or non-living components such as air, water, soil and climatic factors such as sunlight, humidity temperature and wind;
  5. Only forest ecosystems with their flora and fauna are taught.

   

  UNIT 4: Human Body: Endocrine, Circulatory, and Nervous System

  Endocrine system

  • Two types of glands- exocrine and endocrine (the basic concept and difference);
  • Hormone (its definition).
  • Hormonal glands – (thyroid, pancreas, adrenal, pituitary); location and function of each.
  • The following points are to be studied in a tabular form: name of the gland, location in the body, secretion and function.

  Adolescence and the accompanying changes

  • Physical and emotional changes in the body during adolescence.
  • Importance of personal hygiene
  • Stress management (meaning of stress; ways to tackle stress: yoga, meditation, sports, hobbies, time management, rational thinking, etc.)

   

  Circulatory System

  • The internal structure of the heart in detail (including valves, septum, and pacemaker).
  • Schematic diagram of the heart;
  • Blood vessels – aorta, pulmonary trunk, coronary artery & vein, vena cava.
  • Circulation of blood as double circulation.
  • Blood Groups (A, B, AB and O): universal donor and universal acceptor.
  • Conditions related to the functioning of the heart: palpitations, cardiac arrest and hypertension.
  • Introduction of the lymphatic system as a parallel circulatory system.

  Nervous System

  • Types of nerves: sensory, motor, mixed (function only). Cranial and spinal nerves (only definition and number).
  • Structure of a motor neuron
  • Central nervous system (CNS) in detail with its parts and their functions.
  • Reflex action: definition and basic terms used to describe reflex action stimulus, response, impulse, receptor, effector); common examples of reflex action.

   

  UNIT 5: Health and Hygiene

  Diseases

  • A brief idea of communicable diseases (influenza, measles, malaria, dengue, chikungunya, HIV) – causative agents, symptoms, and prevention to be dealt with in a tabular form.
  • The meaning of vectors.
  • Method of preventing diseases in general; use of vaccines to be mentioned.
  • Vaccination and immunisation: the concepts and differences between the two.
  • Harmful effects of consuming tobacco, drinking alcohol and taking drugs.

  First Aid

  • First aid- meaning.
  • First aid is given in the following cases:(burns, bleeding, fracture, object in the eye, unconsciousness, swallowing poison, snake bite, and stings).

   

  UNIT 6: Food Production

  • Bacteria: uses of bacteria in the food industry.
  • Fungi – Importance of mushrooms and yeast in the food industry.
  • Agriculture: cultivated crops (food crops and cash crops), crops grown in India.
  • Horticulture- vegetables, fruits, decorative plants and flowers.
  • Organic farming and green revolution in brief (awareness level).
  • Animal husbandry: milk-yielding (milch) animals; white revolution; meat providing livestock; draught animals (heavy work); poultry; fish farming (pisciculture); sericulture and apiculture (awareness level).

   

   

• Recomended Audience:

  The audience of this course is students of Grade-8from ICSE Board. All the Chapters are well designed and its coverage as per latest curriculum released by the board. Still Student have complete flexibility to enhance or modify the course coverage during the course of learning process with Teacher. We are expecting that students of Grade-8should drive their classes with Teacher as per chapters mentioned and also as per syllabus of their school and applicable School district or Board.

   

• Pre-Requisite Requirement:

  For attending this course, prior knowledge of Grade-7  Biology  is required, this course assumes that students have prior experience with all the topics of Biology  of Grade-7. This is not an introductory class for absolute beginners on Biology  of Grade-7. Participants should already be familiar with the basic learning objective.
