1. 1.Butterflies begin their life as tiny eggs on leaves. A caterpillar hatches from each egg. The caterpillar eats leaves all day and grows bigger and bigger. Then it makes a hard case around itself called a pupa. Inside the pupa, the caterpillar slowly changes. After some days, a beautiful butterfly comes out and flies away.
   
   What is the hard case around the caterpillar called? (a) a hive (b) a shell (c) a nest (d) a pupa
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 weather office (d) the school
3. 3.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 fruits (b) the flowers (c) the roots (d) the leaves
4. 4.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) blue (b) brown (c) green (d) white
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.
   
   What do frogs use to catch insects? (a) long, sticky tongues (b) webbed feet (c) their tails (d) their back legs
6. 6.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 is it called when a seed starts to grow? (a) evaporation (b) digestion (c) germination (d) pollination
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.
   
   Who lays all the eggs in a hive? (a) the worker bees (b) the oldest bee (c) the young bees (d) the queen bee
8. 8.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 is inside a seed? (a) a baby plant (b) a fruit (c) a flower (d) water
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.
   
   Which of these do trees give us? (a) plastic (b) glass (c) metal (d) shade
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) flocks (b) herds (c) hives (d) colonies
11. 11.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.
    
    What do two north poles do? (a) pull each other close (b) stick together (c) push each other away (d) break apart
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 do doctors use to listen to the heartbeat? (a) a thermometer (b) a torch (c) a mirror (d) a stethoscope
