Reading tip (Find the key word): Pick the key word in the question (roots, honey, clouds). Find that word in the passage. Read that sentence carefully — it holds the answer.

1. 1.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 tiny root (b) a shoot (c) a leaf (d) a flower
2. 2.The Moon is Earth’s closest neighbour in space. It does not make its own light. The Moon shines because sunlight falls on it and bounces off. As the Moon goes around Earth, we see different shapes of it. On a full moon night, we see the whole round Moon. On a new moon night, we cannot see the Moon at all. It takes about a month for the Moon to go around Earth.
   
   Why does the Moon shine? (a) it is made of ice (b) it is on fire (c) sunlight bounces off it (d) it has lamps
3. 3.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 cools high up in the sky to form clouds? (a) water vapour (b) smoke (c) dust (d) ice
4. 4.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 leaves (b) the branches (c) the water (d) the soil
5. 5.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.
   
   The heart works like a ___. (a) fan (b) pump (c) bell (d) clock
6. 6.The Moon is Earth’s closest neighbour in space. It does not make its own light. The Moon shines because sunlight falls on it and bounces off. As the Moon goes around Earth, we see different shapes of it. On a full moon night, we see the whole round Moon. On a new moon night, we cannot see the Moon at all. It takes about a month for the Moon to go around Earth.
   
   True or false: The Moon makes its own light. (a) True (b) False
7. 7.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 happens when ice melts? (a) It becomes a cloud (b) It becomes harder (c) It becomes water (d) It becomes steam
8. 8.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. When it rains, the peacock often spreads its tail and dances. The female, called a peahen, is brown and has no long tail. Peacocks eat seeds, insects and even small snakes.
   
   What is the national bird of India? (a) the parrot (b) the crow (c) the peacock (d) the sparrow
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.
   
   In how many forms can water be found? (a) four (b) five (c) two (d) three
10. 10.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.
    
    What protects a camel’s eyes from sand? (a) its wide feet (b) its hump (c) its long neck (d) long eyelashes
11. 11.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.
    
    What do we taste with? (a) our nose (b) our tongue (c) our skin (d) our ears
12. 12.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.
