1. 1.Ants are tiny insects, but they are very strong. An ant can carry things much heavier than its own body. Ants live together in large groups called colonies. Some ants build their homes under the ground, with many rooms and tunnels. When an ant finds food, it leaves a smell trail. Other ants follow this trail to reach the food.
   
   What are large groups of ants called? (a) colonies (b) flocks (c) hives (d) herds
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.
   
   What do we see on a full moon night? (a) half the Moon (b) no Moon (c) a thin Moon (d) the whole round Moon
3. 3.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.
   
   True or false: The peahen has a long tail. (a) True (b) False
4. 4.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 do worker bees collect from flowers? (a) leaves (b) water (c) nectar (d) seeds
5. 5.Plants make their own food in their leaves. To do this, they need sunlight, water and air. The roots take in water from the soil. The green colour in the leaves helps them catch sunlight. Animals cannot make their own food like plants do. That is why plants are very important for all living things.
   
   What helps leaves catch sunlight? (a) the roots (b) the green colour (c) the soil (d) the rain
6. 6.Frogs can live both in water and on land. A frog lays its eggs in water. Tadpoles come out of the eggs and swim with their tails, like tiny fish. Slowly, they grow legs and lose their tails. Then they hop out of the water as young frogs. Frogs catch insects with their long, sticky tongues. In the monsoon, you can hear them croaking loudly.
   
   How do tadpoles swim? (a) with their legs (b) with their tails (c) with their tongues (d) with fins
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.
   
   Who lays all the eggs in a hive? (a) the worker bees (b) the young bees (c) the oldest bee (d) the queen bee
8. 8.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.

   The heart works like a ___. (a) fan (b) clock (c) pump (d) bell
9. 9.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.
   
   Why don’t a camel’s feet sink into the sand? (a) They are wet (b) They are very small (c) They are wide and flat (d) They have claws
10. 10.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 solid (b) a cloud (c) a gas (d) a liquid
11. 11.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.

    How many milk teeth do children have? (a) ten (b) twenty (c) thirty (d) sixteen
12. 12.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.
