Take Care of Your Book Dos: 1. Cover your book with plastic or manila paper. Old newspapers and magazines will do. 2. Be sure your hands are clean when you handle or turn the pages. 3. When using a new book for the first time, lay it on its back. Open only a few pages at a time. Press lightly along the bound edge as you turn the pages. This will keep the cover in good condition. 4. Use a piece of paper or cardboard for bookmarks. 5. Paste or tape immediately any torn pages. 6. Handle the book with care when passing from one person to another. 7. Always keep your book in a clean, dry place. 8. When your book is lost, report it to your teacher right away.

Our eyes help us to see. It has different parts that work together so we can see things around us. The cornea is like a clear glass that covers the front of the eye. The iris is the colored part of the eye. It lets just the right amount of light to enter the eye. At the center of the iris is the pupil. The pupil is a circular hole where light enters. Next to the pupil is the lens. The lens focuses the image we see onto the retina located at the back of the eye. The retina is like a “screen” where the image of the object seen is focused. The optic nerve connected to the eye sends the message to the brain to tell about the image seen. 50

DRAFT April 10, 2014 Parts and Function of our Ears Our ears help us to hear sounds. It has different parts that work together so we can hear sounds. The outside of the ear is called the pinna. This is the part that you can see where the girl’s earring is pierced. The pinna collects sound and directs it into the ear canal. The ear canal is like a tube where ear wax is formed. The ear canal directs the sound into the eardrum located at the end. The eardrum is like a thin piece of skin stretched tight like a drum. When sounds reach the eardrum, it shakes or vibrates. There are three small bones connected behind the eardrum. These bones are called hammer, anvil, and 2. Based on the what you read, labelthese the three parts bones of the stirrup. When eardrum vibrates, of the earone on your . thatdiagram are connected afternotebook. another also vibrate. The cochlea detects the vibration. The cochlea is the snail-like part which is filled with liquid. When the liquid inside the cochlea vibrates, it sends messages to our brain through the auditory nerve to tell us about the sounds we hear.

3. Read about the parts and functions of the nose.
Parts and Function of the Nose Our nose helps us to smell things around us. We use it to breathe. The nose is made up of the nostrils, nasal cavity and nerves. The nostrils are the two holes of the nose. Inside the nostrils are hairs that keep dust out of the nose.When you inhale, air enters the nostrils and passes through the nasal passages and into the nasal cavity. The nasal cavity is the space behind your nose, in the middle of your face. Its walls are wet, warm, and covered with mucus, a sticky liquid. Mucus traps dusts, dirt or germs which enter the nostrils and were not filtered by the nose hairs. Inside the nasal cavity are nerves that pick up the scents carried by air. The nerves in the nasal cavity send messages to the brain which interprets what we have smelled.

The skin is the outer covering of our body. It protects the body from losing too much water, injuries, and infection. It helps maintain body temperature and help us sense our
The skin consists of two layers. The epidermis is the outer layer of the skin on the surface on which dead skin cells are found. This is the part that we can see and touch. The dermis is the inner layer of the skin which contains blood vessels, nerves, sweat glands, and oil glands.
The sweat glands open the surface of the skin through the pore. The oil glands keep the hair and skin soft and moist.
