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.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) two (b) three (c) five (d) four
2. 2.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 colour is a peahen? (a) blue (b) green (c) white (d) brown
3. 3.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 should we not do, according to the passage? (a) reading in dim light (b) sleeping early (c) drinking water (d) washing hands
4. 4.Magnets can pull things made of iron and steel. This pull is called attraction. A magnet cannot pull wood, paper, plastic or glass. Every magnet has two ends called poles: a north pole and a south pole. Two north poles push each other away. A north pole and a south pole pull each other close. Magnets are used in toys, fridge doors and compasses.
   
   What can magnets pull? (a) plastic and glass (b) stone and sand (c) wood and paper (d) iron and steel
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.
   
   What do we taste with? (a) our skin (b) our ears (c) our tongue (d) our nose
6. 6.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.
   
   True or false: The air high up in the sky is cold. (a) False (b) True
7. 7.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.
   
   Why does a bee do a special dance? (a) to tell others the way (b) to scare birds (c) to wake the queen (d) to have fun
8. 8.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) Kerala (b) Assam (c) Sikkim (d) Rajasthan
9. 9.Winds are moving air. A gentle wind is called a breeze, and it feels pleasant on a hot day. A very strong wind with heavy rain is called a storm. A cyclone is a huge storm that forms over the sea and can damage houses and trees. Before a cyclone, the weather office warns people near the coast. People then move to safe places until the cyclone passes.
   
   What is a gentle wind called? (a) a cyclone (b) a breeze (c) a storm (d) a cloud
10. 10.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 is it called when a seed starts to grow? (a) pollination (b) germination (c) evaporation (d) digestion
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.
    
    How many sense organs are there? (a) four (b) five (c) three (d) six
12. 12.Magnets can pull things made of iron and steel. This pull is called attraction. A magnet cannot pull wood, paper, plastic or glass. Every magnet has two ends called poles: a north pole and a south pole. Two north poles push each other away. A north pole and a south pole pull each other close.
