We have five sense organs — eyes, ears, nose, tongue, and skin — and they send messages to our brain about the world. Our eyes see light, colour, shape, size, and movement. Our ears hear sounds — loud and soft, high and low. Our nose smells pleasant smells like flowers and food, and bad smells like smoke and rotten fruit that warn us of danger.
Our tongue has tiny bumps called taste buds that taste sweet, salty, sour, and bitter. Our skin feels touch, pressure, pain, heat, and cold. Some people cannot see or hear. Blind people read with their fingers using raised dots called Braille, and deaf people talk with their hands using sign language. We must protect our sense organs: read in good light, keep the volume low, never poke anything into ears or nose, and wash our skin.
Example: Close your eyes and let a friend give you three things to smell, three to taste, and three to touch. Guess each one without looking!
