1. 1.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.
   
   How many sense organs are there? (a) six (b) five (c) four (d) three
2. 2.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) rain (b) clouds (c) steam (d) ice
3. 3.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 many milk teeth do children have? (a) twenty (b) sixteen (c) ten (d) thirty
4. 4.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) into the water (c) down into the soil (d) up towards the light
5. 5.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 colour is a peahen? (a) brown (b) blue (c) green (d) white
6. 6.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.
   
   Who leads a group of elephants? (a) a tiger (b) the biggest male (c) the youngest calf (d) the oldest female
7. 7.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.
   
   What grows first from the seed? (a) a flower (b) a tiny root (c) a shoot (d) a leaf
8. 8.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.
   
   How long does the Moon take to go around Earth? (a) about a month (b) about a day (c) about a year (d) about a week
9. 9.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.
   
   True or false: The Moon makes its own light. (a) False (b) True
10. 10.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.
