1. 1.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.
   
   Which two things does the Sun give us? (a) light and heat (b) wind and clouds (c) rain and snow (d) food and water
2. 2.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 takes in water from the soil? (a) the flowers (b) the fruits (c) the leaves (d) the roots
3. 3.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.
   
   What is the Sun? (a) a cloud (b) a moon (c) a planet (d) a star
4. 4.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) washing hands (c) drinking water (d) sleeping early
5. 5.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) three (b) five (c) four (d) two
6. 6.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) Rajasthan (b) Assam (c) Sikkim (d) Kerala
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 scare birds (b) to have fun (c) to wake the queen (d) to tell others the way
8. 8.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.
   
   Which of these do plants need to make food? (a) sunlight (b) salt (c) sand (d) darkness
9. 9.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.
   
   Who builds nests in trees? (a) frogs (b) cows (c) birds (d) fish
10. 10.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.
    
    True or false: Animals can make their own food like plants. (a) False (b) True
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 tongue (b) our ears (c) our skin (d) our nose
12. 12.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.
    
    What does blood carry to every part of the body? (a) air and smoke (b) food and oxygen (c) water and salt (d) light and heat
