Answer 1

1. Children - Has this ever happened to you:
3. You were eating in the playground, an eagle flew down and took away your roti. As you walked softly past a sleeping dog, its ears shot up at once.
5. 
7. You dropped something sweet on the ground and within minutes many ants collected around it.
9. 
11. Why does it happen:
13. Animals also have different senses. They can see, hear, taste, smell and feel. Some animals can see their prey from far away. Some can hear even the faintest sound. 
15. 
17. Some animals can find their friends by their smell. The animal world is full of examples of amazing senses!

21. SENSE ORGANS
23. The sense organs are eyes, ears, tongue, skin, and nose. There are five senses: sight, hearing, taste, smell and touch.
25. 
27. How did the ant recognise a friend:
29. An ant was going along on the ground. It saw a group of ants coming from the other side. The first ant quickly came back to its hole. The ant guarding the hole recognised it and let it in.
31. 
33. Many years ago a scientist did many experiments like this. He found out that as the ants move, they leave a smell on the ground. The other ants follow the smell to find the way.
35. 
37. Now can you guess why the ants behaved like that when you blocked their path? Some male insects can recognise their females by their smell.
39. 
41. Have you ever been troubled by mosquitoes. Just think, how do they know where you are? Mosquitoes can find you by the smell of your
43. body. They also find you by the smell of the sole of your feet and the heat of your body.

47. I am a silk worm. I can find my female worm from many kilometres away by her smell.

59. 
61. It was funny that both the babies did potty at the same time. She happily cleaned her daughter but when she was cleaning her sister’s son Deepak, she covered her nose with her dupatta (scarf).
63. 
65. Most of the birds have their eyes on either side of the head.Their eyes can focus on two different things at a time. When they look straight ahead, both their eyes focus on the same object. 
67. 
69. You must have seen birds moving their neck very often. Do you know why? In most of the birds, eyes are fixed and cannot move. So birds have to turn their heads to see around.
71. 
73. Some birds like kites, eagles, vultures can see four times as far as we can. These birds can see things from a distance of eight metres what we can see from a distance of two metres._ Now can you guess from what distance can an eagle in the sky can see a roti on the ground?
75. 
77. Do animals see colours:
79. Animals cannot see as many colours as we can. See how things in these pictures will be seen by some animals.

89. In Class IV, you read that we cannot easily see birds’ ears. Their ears
91. are small holes covered with feathers.
