   Which of these does an elephant use its trunk for? (a) sleep (b) hear (c) smell (d) see
2. 2.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.

   Which two things does the Sun give us? (a) rain and snow (b) light and heat (c) wind and clouds (d) food and water
4. 4.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.
   
   Where do plants make their food? (a) in their roots (b) in their flowers (c) in the soil (d) in their leaves

   What do doctors use to listen to the heartbeat? (a) a mirror (b) a stethoscope (c) a torch (d) a thermometer
6. 6.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) two (b) four (c) three (d) five
7. 7.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.

8. 8.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.

Bees also help plants by carrying pollen from flower to flower.
   
   What is the home of honeybees called? (a) a den (b) a nest (c) a burrow (d) a hive
9. 9.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 skin (c) our ears (d) our nose
10. 10.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.
