My Senses

I hear many sounds with my ears. Some sounds are loud and some are soft.

What are the sounds you hear every day around you? Which sounds do you like?

• Let us play a game.

Blindfold yourself. Let your friends move around you while they make sounds. Find the direction of the sound you hear. Identify your friends with their voices.

We see the world around us with our eyes. We see different shapes, sizes and colours.

• Observe the picture and discuss.

• Look at the shapes given below. Can we try the same shapes with our body?

We see and hear the world around us. We also use our senses of touch, smell, taste and to know the world around us.

The lemon is sour, the Mango is sweet and the bitter guard is bitter.
