🎯 Learning outcomes
- Name external body parts and the five sense organs
- Tell what each sense organ helps us do
- Follow simple habits of cleanliness and safety
Before you start: Naming parts of the body.
📖 Explanation
Our body has many parts: head, neck, arms, hands, legs, feet. We have five sense organs: eyes to see, ears to hear, nose to smell, tongue to taste and skin to feel touch, heat and cold.
Sense organs keep us safe: the nose smells smoke, ears hear a horn, eyes see a puddle, skin feels a hot pan.
Good habits keep us healthy: wash hands with soap before eating and after using the toilet, brush teeth twice a day, bathe daily, trim nails and wear clean clothes.
During the monsoon many children in India fall ill from dirty water and unwashed hands; washing hands with soap for 20 seconds helps stop germs.
✗ If hands look clean, they are clean
✓ Germs are too small to see; wash hands with soap even when they look clean.
🧪 Try this activity
Close your eyes. A friend gives you a lemon, a flower, a bell and a piece of cotton. Use your other senses to guess each and name the sense you used.

💬 Questions and answers
1What am I looking at?
Answer: A see-through human body showing the major organs and bones in their real positions.
2What are its parts? (click a part to identify it)
Answer: Brain and spinal cord (nervous), windpipe, lungs and diaphragm (respiratory), heart and blood vessels (circulatory), food pipe, stomach, liver, pancreas and intestines (digestive), kidneys and bladder (excretory), glands (endocrine) and the skeleton.
3How does it work?
Answer: Organs work in teams called systems. Food is digested and absorbed, the lungs take in oxygen, the heart pumps blood that carries both to every cell, the kidneys remove waste, and the brain controls everything.
4Why is it important?
Answer: Knowing where organs are and what they do helps you understand health, illness, first aid and the human-biology chapters of Classes 5 to 12.
5What happens if I change something? (use the sliders)
Answer: Switch systems on and off to see one team at a time, take the body apart to separate organs, and make the skin clearer or more solid.
6What should I remember for the exam?
Answer: Organ system → organs → function. Example: digestive system = mouth, oesophagus, stomach, small and large intestine, with liver and pancreas.
