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.
   
   Which way does the shoot grow? (a) sideways (b) up towards the light (c) down into the soil (d) into the water
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.
   
   What do people near the coast do before a cyclone? (a) open windows (b) go to the beach (c) go fishing (d) move to safe places
3. 3.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) water (b) seeds (c) leaves (d) nectar
4. 4.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.
   
   How often should we brush our teeth? (a) twice a day (b) once a day (c) once a week (d) five times a day
5. 5.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 tongues (b) with fins (c) with their tails (d) with their legs
6. 6.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 nose (c) our ears (d) our tongue
7. 7.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
8. 8.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 does water become when it freezes? (a) ice (b) clouds (c) steam (d) rain
9. 9.Elephants are the largest animals that live on land. An elephant uses its long trunk to breathe, smell, drink and pick up food. It sucks water into its trunk and then sprays it into its mouth. Elephants have big ears that flap to keep them cool. They live in groups led by the oldest female. In India, elephants live in forests in Kerala, Karnataka, Assam and other states.
   
   Which of these does an elephant use its trunk for? (a) hear (b) sleep (c) smell (d) see
10. 10.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 does the pattern on each feather look like? (a) a moon (b) a leaf (c) a star (d) an eye
11. 11.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) food and water (b) rain and snow (c) light and heat (d) wind and clouds
12. 12.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
