Reading tip (Cause and effect): Find the topic of the passage in the first sentence. Look for cause-and-effect words: because, so, as a result. Work out new science words from the sentence that explains them.

1. 1.Bees visit flowers to collect sweet nectar. While they feed, yellow dust called pollen sticks to their hairy bodies. When a bee flies to the next flower, some pollen rubs off. This carrying of pollen is called pollination. Pollination helps plants make fruits and seeds. Mangoes, apples and many vegetables depend on it. Without bees, farmers would harvest far less food. So bees are tiny helpers of every farm.
   
   What is the yellow dust on flowers called? (a) nectar (b) pollen (c) honey (d) wax
2. 2.In many Indian cities, people face water shortages in summer. Rainwater harvesting is one simple answer. Rain falling on rooftops is collected through pipes. It is then stored in tanks or sent into the ground through pits. Water sent into the ground raises the level of water in wells. A single roof can collect thousands of litres in one monsoon. Some states have made rainwater harvesting compulsory for new buildings. Saving rain today means more water tomorrow.
   
   What rises when water is sent into the ground? (a) The roof height (b) Soil heat (c) Water in wells (d) Rainfall
3. 3.The monsoon is a seasonal wind that brings rain to India. In summer, the land heats up faster than the sea. Moist winds then blow from the sea towards the land. The south-west monsoon usually reaches Kerala in early June. Over the next few weeks, it spreads across most of the country. Farmers wait eagerly for it because many crops need its rain. Rice, for example, grows in fields full of water. A weak monsoon can mean a poor harvest.
   
   What can a weak monsoon mean? (a) A poor harvest (b) More rice (c) A cold winter (d) A big flood
4. 4.Lightning is a giant spark of electricity in the sky. It happens when electric charges build up inside storm clouds. A flash of lightning heats the air around it very quickly. The hot air expands with a loud bang, which we hear as thunder. Light travels much faster than sound. That is why we see the flash before we hear the thunder. During a thunderstorm, stay indoors and away from tall trees. Standing under a tree is not safe, as lightning often strikes tall objects.
   
   Where should you stay during a thunderstorm? (a) Under a tree (b) On a rooftop (c) Indoors (d) In an open field
5. 5.Lightning is a giant spark of electricity in the sky. It happens when electric charges build up inside storm clouds. A flash of lightning heats the air around it very quickly. The hot air expands with a loud bang, which we hear as thunder. Light travels much faster than sound. That is why we see the flash before we hear the thunder. During a thunderstorm, stay indoors and away from tall trees. Standing under a tree is not safe, as lightning often strikes tall objects.
   
   What is lightning? (a) A burst of rain (b) A falling star (c) A gust of wind (d) A spark of electricity
6. 6.Bees visit flowers to collect sweet nectar. While they feed, yellow dust called pollen sticks to their hairy bodies. When a bee flies to the next flower, some pollen rubs off. This carrying of pollen is called pollination. Pollination helps plants make fruits and seeds. Mangoes, apples and many vegetables depend on it. Without bees, farmers would harvest far less food. So bees are tiny helpers of every farm.
   
   Why do bees visit flowers? (a) To collect nectar (b) To sleep (c) To lay eggs (d) To find water
7. 7.The monsoon is a seasonal wind that brings rain to India. In summer, the land heats up faster than the sea. Moist winds then blow from the sea towards the land. The south-west monsoon usually reaches Kerala in early June. Over the next few weeks, it spreads across most of the country. Farmers wait eagerly for it because many crops need its rain. Rice, for example, grows in fields full of water. A weak monsoon can mean a poor harvest.
   
   Why do farmers wait eagerly for the monsoon? (a) Schools close (b) Crops need its rain (c) It is cool (d) It brings snow
8. 8.Bees visit flowers to collect sweet nectar. While they feed, yellow dust called pollen sticks to their hairy bodies. When a bee flies to the next flower, some pollen rubs off. This carrying of pollen is called pollination. Pollination helps plants make fruits and seeds. Mangoes, apples and many vegetables depend on it. Without bees, farmers would harvest far less food. So bees are tiny helpers of every farm.
   
   What would happen without bees? (a) Farmers get less food (b) More rain would fall (c) Farms become quieter (d) Flowers grow bigger
9. 9.The Earth spins like a top on an imaginary line called its axis. One full spin takes about twenty-four hours. As the Earth spins, one half faces the Sun and has day. The other half faces away and has night. The Earth also moves around the Sun. One trip around the Sun takes about 365 days, which is one year. The tilt of the Earth’s axis gives us seasons. So spinning gives us day and night, while the tilt and the yearly trip give us seasons.
   
   How long does one full spin take? (a) About one hour (b) About one week (c) About twenty-four hours (d) About 365 days
10. 10.Mangroves are trees that grow in salty water along the coast. Their roots stick out of the mud like knobbly fingers. These roots help the trees breathe in wet, airless soil. Mangrove forests protect the coast from strong waves and storms. They also give shelter to fish, crabs and birds. The Sundarbans, shared by India and Bangladesh, is the largest mangrove forest in the world. It is home to the Royal Bengal tiger. Cutting mangroves leaves the coast open to damage.
    
    Where do mangroves grow? (a) In deserts (b) On high mountains (c) In cold forests (d) In salty coastal water
11. 11.Lightning is a giant spark of electricity in the sky. It happens when electric charges build up inside storm clouds. A flash of lightning heats the air around it very quickly. The hot air expands with a loud bang, which we hear as thunder. Light travels much faster than sound. That is why we see the flash before we hear the thunder. During a thunderstorm, stay indoors and away from tall trees. Standing under a tree is not safe, as lightning often strikes tall objects.
    
    Why is standing under a tree unsafe? (a) Leaves are wet (b) Birds live there (c) It strikes tall objects (d) Trees fall in rain
12. 12.Green plants make their own food. This process is called photosynthesis. Leaves take in carbon dioxide from the air through tiny holes. Roots take up water from the soil. A green substance in the leaves, called chlorophyll, traps sunlight. Using the energy of sunlight, the leaf turns water and carbon dioxide into sugar. Oxygen is given out into the air. Animals and people breathe in this oxygen.
    
    Which gas is given out during photosynthesis? (a) Water vapour (b) Carbon dioxide (c) Oxygen (d) Smoke
