Our Body and Health
Overview
"Our Body and Health" is a foundational topic in Environmental Studies (EVS) for Varg-3 (Primary Level) of MP TET. This topic integrates basic biology with health education, making it essential for teaching young learners about themselves and healthy living practices.
In the exam, expect questions on identification of body parts and their functions, the five sense organs and their roles, personal hygiene practices, and common childhood diseases with prevention methods. Questions often use child-friendly scenarios—matching sense organs to functions, identifying healthy habits from pictures, or recognizing symptoms of common ailments.
Mastering this topic requires understanding both the content knowledge and how to make it relatable for children aged 6–11 years. Teachers must connect abstract concepts (like digestion or circulation) to children's everyday experiences in MP's diverse rural and urban contexts.

Key Concepts
- **External body parts** include head, neck, trunk (chest and abdomen), arms, hands, legs, and feet. Children learn to name, locate, and understand basic functions of each part.
- **Internal organs** perform life-sustaining functions: heart pumps blood, lungs help breathing, stomach digests food, brain controls the body, and kidneys filter waste.
- **Five sense organs** connect us to the environment: eyes (sight), ears (hearing), nose (smell), tongue (taste), and skin (touch). Each has a specific receptor that sends signals to the brain.
- **Personal hygiene** refers to daily practices that maintain cleanliness and prevent disease—bathing, brushing teeth, handwashing, nail trimming, and wearing clean clothes.
- **Balanced diet** includes carbohydrates, proteins, fats, vitamins, minerals, and water in proper proportions. Local foods like dal-chawal, sabzi, roti, and fruits provide these nutrients.
- **Communicable diseases** spread from person to person through air, water, food, or contact (e.g., cold, flu, diarrhoea, chickenpox). **Non-communicable diseases** do not spread (e.g., diabetes, asthma).
- **Vaccination/Immunization** protects children from serious diseases like polio, measles, tuberculosis, and hepatitis. India's Universal Immunization Programme covers these.
- **First aid** refers to immediate care given before medical help arrives—cleaning wounds, applying bandages, and keeping the patient calm.
