relating to forming of natural, social,

4. What is the purpose of

Explanation text is to say 'why' and 'how'
about the forming of the phenomena.
5. Generic Structure of Explanation:
• A general statement which describes or
identifies the phenomenon

6. How Rainbow is Formed?
Rainbow is one of optic phenomena that happens in the
atmosphere of the earth naturally. We can see it at mountin range,
or when it is cloudy, or when it is raining and rising of sun. We can see it
perfectly, if it is seen by standing in the high place. It is real that rainbow is
a circle form not like parabola form. When we are looking at rainbow’s
colors, we will see them that ordered of red is on the highest order, and
purple is on the lowest order.
Red is more dominant than another color caused by having biggest
wave between others. Therefore the red one is in the highest order and
purple one is in lowest order. How rainbow is formed? Try to watch it
when light of sun concerns a 90-degree angle mirror or a glass prism side,
or surface of soap foam. We can see colors on the light. The light is rayyed
to be some wave lenght of light that it is seen by our eyes as red, bright
red, yellow, green, blue and purple. These colors are components of light
that they are called visible light. The other component is invisible light
such as infrared (red is in the right side), and ultraviolet (bright red is in
the left side).
So, we can see the beautiful rainbow because there are some
processes to be beautiful rainbow that it appears in the sky.

8. How Do Bees Make Honey?
Bees are useful insects. There are about 20,000
kinds of bees, but only honey bees make honey. Honey
bees live in groups called colonies. Each colony has one
female queen bee, ten of thousands or workers , and a few
hundred male bees or drones. Honey bees lives in hives.
Inside their hive, the bees make a honey comb of wax. The
honey comb is a kind of bee apartment building full of six –
sided room s in which the bees raises young and store food.
The queen bee lays thousands of eggs. Worms look like
larvae hatch from eggs. Each larva becomes a pupa, which
looks partly like larva and partly like an adult bee. Worker
bees feed the young , clean, guard the hive, and fly to and
from flowers. They collect tiny grains of pollen and a sweet
liquid called nectar for food. The pollen is food for young
bees. Worker bees use the nectar to make honey. Without
bees bringing pollen from flower to flower, many plants can’t
make seeds.
