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.
   
   Where do some ants build their homes? (a) on water (b) in birds’ nests (c) under the ground (d) in the sky
2. 2.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.
   
   Who warns people before a cyclone? (a) the fishermen (b) the post office (c) the school (d) the weather office
3. 3.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 is the camel called? (a) the king of the jungle (b) the desert horse (c) the sand king (d) the ship of the desert
4. 4.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 has lamps (b) it is made of ice (c) sunlight bounces off it (d) it is on fire
5. 5.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 clouds (b) the wind (c) the Sun (d) the Moon
6. 6.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 do people near the coast do before a cyclone? (a) go fishing (b) move to safe places (c) open windows (d) go to the beach
7. 7.The Sun is a star, the closest one to Earth. It is a huge ball of very hot gases. The Sun gives us light and heat. Without the Sun, there would be no plants, animals or people on Earth. The Sun looks small only because it is very far away. We must never look straight at the Sun, because it can hurt our eyes.
   
   Why must we never look straight at the Sun? (a) It can hurt our eyes (b) It is too far (c) It moves fast (d) It is rude
8. 8.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 making shade (b) by carrying pollen (c) by eating leaves (d) by watering them
9. 9.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.
   
   True or false: A magnet can pull a plastic ruler. (a) False (b) True
10. 10.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) hives (b) herds (c) colonies (d) flocks
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. 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 can cause holes in our teeth? (a) fresh water (b) brushing (c) sticky sweets (d) green leaves
12. 12.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 steam (b) It becomes a cloud (c) It becomes water (d) It becomes harder
