3. 3.Honeybees live together in a home called a hive. A hive has one queen bee, who lays all the eggs. The worker bees collect nectar from flowers and turn it into honey. They also clean the hive and look after the young bees. When a bee finds flowers, it does a special dance to tell the others where to go. Bees also help plants by carrying pollen from flower to flower.
   
   How do bees help plants? (a) by watering them (b) by eating leaves (c) by making shade (d) by carrying pollen
4. 4.A seed has a baby plant inside it. When a seed gets water, air and warmth, it starts to grow. This is called germination. First, a tiny root grows down into the soil. Then a small shoot grows up towards the light. Soon the first green leaves open. You can watch this happen by keeping a few moong seeds on wet cotton.
   
   What grows first from the seed? (a) a leaf (b) a shoot (c) a flower (d) a tiny root
5. 5.Our eyes help us see colours, shapes and light. Our ears help us hear sounds. We smell with our nose and taste with our tongue. Our skin helps us feel if something is hot, cold, rough or smooth. These five are called our sense organs. We must take care of them, for example, by not reading in dim light.
   
   How many sense organs are there? (a) five (b) six (c) four (d) three
6. 6.The camel is called the ship of the desert. It can walk for many days on hot sand without drinking water. Its long eyelashes protect its eyes from blowing sand. Its wide, flat feet do not sink into the sand. The hump on its back stores fat, not water. In India, camels are found in the deserts of Rajasthan.
   
   Where are camels found in India? (a) Assam (b) Sikkim (c) Rajasthan (d) Kerala
7. 7.Butterflies begin their life as tiny eggs on leaves. A caterpillar hatches from each egg. The caterpillar eats leaves all day and grows bigger and bigger. Then it makes a hard case around itself called a pupa. Inside the pupa, the caterpillar slowly changes. After some days, a beautiful butterfly comes out and flies away.
   
   What is the hard case around the caterpillar called? (a) a hive (b) a nest (c) a pupa (d) a shell
8. 8.Trees are very useful to us. They give us fruits, wood and shade. Trees take in the air we breathe out and give out oxygen, the gas we need to live. Their roots hold the soil together, so it is not washed away by rain. Birds build nests in trees, and many insects live on them. That is why we should plant more trees and not cut them down.
   
   What do tree roots hold together? (a) the water (b) the leaves (c) the branches (d) the soil
9. 9.Our teeth help us bite and chew food. Children have twenty milk teeth, which fall out one by one. New, stronger teeth grow in their place. Sugary food and sticky sweets can cause holes in our teeth. So we should brush our teeth twice a day, in the morning and at night. We should also rinse our mouth with water after every meal.
   
   What grows in place of the milk teeth? (a) stronger teeth (b) soft teeth (c) no teeth (d) more milk teeth
10. 10.Butterflies begin their life as tiny eggs on leaves. A caterpillar hatches from each egg. The caterpillar eats leaves all day and grows bigger and bigger. Then it makes a hard case around itself called a pupa. Inside the pupa, the caterpillar slowly changes. After some days, a beautiful butterfly comes out and flies away.
    
    What hatches from a butterfly egg? (a) a bee (b) a caterpillar (c) a worm (d) a butterfly
11. 11.Butterflies begin their life as tiny eggs on leaves. A caterpillar hatches from each egg. The caterpillar eats leaves all day and grows bigger and bigger.

12. 12.Our heart is a strong muscle about the size of our fist. It works like a pump and pushes blood all around the body. The heart never stops, even when we are asleep. Blood carries food and oxygen to every part of the body. When we run or play, our heart beats faster. Doctors listen to the heartbeat with a stethoscope.
