20. Every part of the peoples 5
senses has a job.

21. Cornea-its like a clear mirror which covers the first
layer of an eye.
Iris-is the part that has color. This is the one who
brings light into our eyes.
Pupil-is in the middle of the iris.Its circle and this is
where the light enters our eye.
Lens-This is in the middle part of an eye which
gives pictures or things that can see in retina.
Retina-is like a curtain that covers the eye to
focus on something we see
Optic nerve-connect the eye to the brain. They
give message to the thing we see.

22. Answer the following questions.
1.Is an eye helpful to a person? Why?
2.Which part of the eye is like a clear mirror that
covers the first layer?
3.Which part connects the eye to the brain and
gives message to something we see?
4.Which part of the eye is like a curtain which

5.Is it right to take care of our eye?why?

23. Ears helps us too listen to something. There
are different parts of the ear. The outer part of
the ear is called pinna. This is the part that we
can see and this is where we put our earing.
This part recieves sounds bringing to the ear
canal. Ear canal is a tube where ear wax is
formed. The ear canal sends the message to
the ear drum. Ear drum is a thin skin which is
so streched just like a drum. When a sound
reached the ear drum, it will vibrate.

24. There are three seeds connected to each
other at the back of the eardrum. Those are
hammer, anvil, and stirrup. When the eardrum
vibrates, the little seeds will vibrate as well.
The cochlea can feel the vibration. The
cochlea shapes like a snails shell that has
liquid inside. When the liquid inside vibrates, it
sends message to the brain by the auditory
nerve which gives knowledge to the sound we
hear.

25. Answer the following questions.
1.What are the three little seeds connected to
each other at the back of the eardrum?
2.What is pinna?
3. What is ear canal?
4.What is the auditory nerve?
5.What is cochlea?

26. Our nose helps us to smell everything
around us. We use it to breath. This
is made by nostrils, nasal cavity, and
nerves. Nostrils is the little hole we
can see. Inside the nostrils has a
hair which helps to segragate the
dirt. When we smell air it goes to the
nostrils going to the nasal passages
going to nasal cavity. Nasal cavity is
the part at the back of the nose at
the middle of our face. The walls of
this part is wet, hot, and covered
with mucus. Mucus is sticky liquid.

27. This part segregates the dirt and
germs that is not being segregates
by the hair inside the nostrils. Inside
the nasal cavity is the nerves that
gets the smell that the air brings.
The roots sends the message in the
nasal cavity and gives knowledge to
what we see.

28. 1. What are the part of the nose?
2. What is the nose made of?
3. What are nostrils and what are inside of it?
4. Where is the air going after passing throught
the nostrils?
5.Whats inside the nasal cavity?
REMEMBER:
Our nose help us to breath, every part of the
nose inside has a job .

29. Our tongue is a part of the five senses which helps
us to taste. Here are the taste buds. The taste of the
food goes to the taste buds and at the end of the
roots. The roots sends the message to the brain and
gives knowledge to the taste of the food we eat.
REMEMBER:
Our tongue helps us to taste everything.
Same as the other senses. Every part has a job.

30.  Our skin is the outer part of the 5 senses which
covers the whole body. This is the safeguard for
the exhaustion of water, damage, and germs. It
helps to maintain the temperature in our body and
the sensory around. Its made of the two parts. The
epidermis is the first part this is the outer part of
the skin where we see the dead skin cells. We can
see and feel this part. The dermis is in the lower
part that covers blood vessels, nerves, sweat and
oil glands.
