Sense Organs
What you'll learn
- We have five sense organs: eyes, ears, nose, tongue, and skin.
- Eyes help us see; ears help us hear.
- Nose helps us smell; tongue helps us taste.
- Skin helps us feel (touch, heat, cold, pain).
Key concepts
Level 1 — Core idea
Verbal: Each sense organ sends a message to the brain about the world.
Symbolic: Eye → see, Ear → hear, Nose → smell, Tongue → taste, Skin → touch.
Visual: Draw a face and label eyes, ears, nose, tongue, and mark skin all over.
Level 2 — Going deeper
Some people cannot see or hear well. They use other senses more sharply to help, like reading Braille by touch.
NCERT anchor
NCERT Looking Around 3 discusses how we use our senses to observe plants and animals during nature walks.
