   What do people near the coast do before a cyclone? (a) go fishing (b) go to the beach (c) move to safe places (d) open windows
4. 4.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.

   What does the caterpillar eat? (a) insects (b) flowers (c) seeds (d) leaves

7. 7.The peacock is the national bird of India. The male peacock has a long tail with shining blue and green feathers. Each feather has a pattern that looks like an eye.

   What is the national bird of India? (a) the crow (b) the peacock (c) the parrot (d) the sparrow
8. 8.Rain begins with the Sun heating water in seas, rivers and lakes. The warm water turns into water vapour and rises into the sky. High up, the air is cold, so the vapour cools and forms tiny drops. Many drops join together to make clouds. When the drops become too heavy, they fall as rain. This journey of water is called the water cycle.
   
   What heats the water in seas and rivers? (a) the Moon (b) the Sun (c) the wind (d) the clouds
9. 9.Water can be found in three forms. When water freezes, it becomes solid ice. When ice melts, it turns back into liquid water. When water is heated, it turns into steam, which is a gas. We use ice to keep drinks cold on hot days. Clouds are formed when water vapour cools high up in the sky.
   
   What is steam? (a) a cloud (b) a liquid (c) a solid (d) a gas
10. 10.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 soil (b) the leaves (c) the water (d) the branches
11. 11.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.
    
    What is the home of honeybees called? (a) a hive (b) a nest (c) a den (d) a burrow
12. 12.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 shoot (b) a tiny root (c) a leaf (d) a flower
