Another type of new world monkey is the Bald Uakari.
This type of monkey has a bright red face and a bald head.
It lives in South America, spending most of its life in the trees.
Bald Uakari monkeys grow to be about 7 pounds and 18 inches long, and eat mostly fruits, nuts and bugs.
Even though their red face and bald head look weird, a healthy red face means that this type of monkey is healthy!
Inside the Cochlea are tiny microscopic hairs that move when sound hits them.
When these hairs move, the part of the body they are attached to lets out some chemicals.
Those chemicals then touch some other cells in the body which let out electricity.
That electricity sends the message to the brain that the body heard a sound.
Depending on how loud, soft, high or low the sound is, the hairs will wiggle differently,
and that will send different chemicals and different electricity to the brain to tell you what sounds you are hearing.
Let's learn a little about the country of Vietnam, also called the Socialist Republic of Vietnam.
Vietnam is a small country in Asia, about 128,000 square miles, with about 96 million people liveing there.
It borders China, Laos, Cambodia, Thailand, Phillippines, Indonesia, Malaysia and the South China Sea.
To eat in Vietnam you might have bún chả, which is pork with noodles served over rice noodles and dipping sauce.
The word bún means noodles and chả means pork.
Visiting Vietnam you might go see Ban Gioc-Detian Falls, some big waterfalls in the country.

Rice farming is a very important business in Vietnam, and rice is grown there in what are called terraces, that look like stairs.

Another famous Christmas song is Hark! The Herald Angels Sing.
This was first written by Charles Wesley in 1739 in England.
When Wesley first wrote it, he called it "Hark! how all the welkin rings", where the word welkin means sky.
In 1840 another person changed it to the words Hark! The Herald Angels Sing that we know of today.
The tune for the song is from the famous composer Felix Mendelssohn's music called Festgesang.
Hark! The herald-angels sing "Glory to the newborn king;
Peace on earth and mercy mild, God and sinners reconciled"
Joyful all ye nations rise, Join the triumph of the skies
With the angelic host proclaim "Christ is born in Bethlehem"
Hark! The herald-angels sing "Glory to the new-born king"
Christ, by highest heaven adored Christ, the everlasting Lord,
Late in time behold Him come Offspring of a Virgin's womb:
Veiled in flesh the Godhead see, Hail the incarnate Deity
Pleased as man with man to dwell Jesus, our Emmanuel
Hark! The herald-angels sing "Glory to the newborn King"
Hail the Heaven-born Prince of Peace! Hail the Sun of Righteousness!
Light and life to all He brings, Risen with healing in His wings;
Mild He lays His glory by Born that man no more may die
Born to raise the sons of earth Born to give them second birth
Hark! The herald angels sing "Glory to the new-born king"
Another famous thing Leonard did was make Anatomical Drawings.
This means he studied things like arms and legs, and tried to draw sketches of how they work.
He made drawaings of how the human body moves, and even some pictures of what he thought babies looked like before being born.
Da Vinci studied humans and other animals too, and made many drawings about how a bird is able to fly.
This is the part of the computer that you look at, that shows all of the pictures and videos that your computer puts on it.
Through the years computer monitors have changed a lot.
Long ago they only had a black background with white or green text.
Then later monitors could display every color, and also draw pictures on the screen for things like video games or office work.
For a long time, computer monitors were very big, using what were called Cathode Ray Tubes or CRTs to show things on the monitor.
They were later replaced by flat screen monitors, usually called Liquid Crystal Displays or LCD.
LCDs are much thinner, lighter, and usually taller and wider than the old CRT displays.
Some old CRTs could weigh 50 pounds, compared to an LCD with the same screen size weighing only 10 pounds.
Because flat screen monitors could be made so thin and light, people could make computers so small they could fit on your lap, called laptops!
