      • Interdependence between organisms: symbiosis, parasitism and predation
      • Brief account of abiotic or non-living components such as air, soil, water and climatic factors such as sunlight, temperature, humidity and wind;
      • Only, forest ecosystem with its flora and fauna to be taught.
  • Human Body:Endocrine, Circulatory and Nervous System :
  • Endocrine System
  • Two types of glands- exocrine, endocrine (basic concept and difference);
  • Hormone (definition).
  • Hormonal glands – (thyroid, adrenal, pancreas, pituitary); location and function of each.
  • Following points to be studied in tabular form: name of gland, location in body, secretion, function.
  • Adolescence and 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, time management, sports, hobbies, rational thinking etc.)
    • Circulatory System
      • Internal structure of heart in detail (including valves, septum; 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 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.
  • 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 vector.
        • Method of preventing diseases in general; use of vaccines to be mentioned.
        • Vaccination and immunization: the concepts and difference between the two.
        • Harmful effects of consuming tobacco, drinking alcohol, taking drugs.
      • First Aid
        • First aid- meaning. First aid given in the following cases:(burns, bleeding, fracture, object in the eye, unconsciousness, swallowing poison, snake bite, stings).
  • Food Production
    • Bacteria: uses of bacteria in food industry.
    • Fungi – Importance of mushrooms and yeast in 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 (pisiculture); sericulture and apiculture (awareness level).
