1. AIR: Air is present all around us. We feel the air when it moves but we can't see air. All living things need air to breathe. Without air, there will be no life on the earth.


Uses of Air:

  • Plants and animals need air to breathe.
  • Air can fill balloon, football etc.
  • Air has weight.
  • Fire needs air to burn

Air cannot be seen, we can only feel air. Moving air is called wind. The slow moving wind is called breeze. The fast moving wind is called storm which can damage your house



Water is needed for life. Plants and animals need water. Water is present in oceans, river lakes, ponds.   We need water for drinking, bathing, cooking and washing.




Water is very essential for our life. Life not possible without water. Water can stored in dams, wells, ponds, rivers, lakes etc. We should not waste water. Water can be reused for various purposes such as cleaning, washing, irrigation etc. This is called water conservation.

2. MOON: The Moon shines at night. The Moon looks like a big white ball. The shape of the Moon changes every night. Moon does not have its own light


3. STAR: We see stars in the sky at night. Stars are very far from us, that is why they appear very small.
