What grows first from the seed? (a) a leaf (b) a flower (c) a tiny root (d) a shoot -
5.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) ice (c) steam (d) clouds -

Which of these does an elephant use its trunk for? (a) see (b) smell (c) sleep (d) hear -
7.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.

It takes about a month for the Moon to go around Earth.

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

How big is our heart? (a) the size of our head (b) the size of our fist (c) the size of a pea (d) the size of a ball -

Magnets are used in toys, fridge doors and compasses.
True or false: A magnet can pull a plastic ruler. (a) False (b) True -
