Cochlea


We just learned about the Semicircular Canals.

Another part of the bony labryinth in the inner ear is the Cochlea.

This is a spiral that sounds go into, and there are little hairs inside the spiral that send signals to the brain telling it what sounds are being heard.
The different parts of the spiral help the ear listen to different types of sounds.
At the opening the spiral collects sounds that are high pitched like a whistle.
As the spiral goes in further the sounds get lower, more like a big drum beating.

All of these different sounds get sent to the brain to hear all the different highs and lows.

The name cochlea comes from the greek word for spiral snail shell.

We just learned about the country of United Arab Emirates

Let's learn a little about the country of Turkmenistan!

This is a country in the middle east, bordring Kazakhstan, Uzbekistan, Afghanistan, Iran, and the Caspian Sea.
It is about 190,000 square miles, and about 6 million people live there.

The flag of Turkemnistan is green with a red stripe on the left with carpet designs on the red above olive branches.
On the right is a white crescent moon and five stars.
The moon is for hope, the stars are for the provinces in the country, the carpet is for the tribes of people who founded the country.

To eat in Turkmenistan, you might have melons!
This country was once famous for growing all kinds of melons, and they grow over 400 different kinds of melon.

Visiting Turkmenistan you might go see the Darvasa gas crater.
This is a hole in the ground that is abotu 200 feet across and about 60 feet deep.
A long time ago people were drilling for oil in the area, and found a place where gas was leaking out from the ground.
They lit the ground on fire to help get rid of the gas leak, but it never stopped burning and the crater has now been burning for over 50 years.

There is a national holiday in Turkmenistan called Melon Day, because there are so many melon farms in the country.
Every year the second Sunday in August the people get together in the city of Ashgabat and have music, dancing and lots of melons.

Away in a Manger


We just learned about the Christmas song We Three Kings.

Another famous Christmas song is Away in a Manger.

For a very long time, people thought that the words for this song were written in 1883 by Martin Luther, and it was even sometimes called Luther's Cradle Song.
But after going back and looking at the writing, people now think that the words were first written in English somewhere earlier in America, and then later translated to German.

There are two popular tunes that people sing this song to. The one that is most popular in America was wrriten by James R. Murray in 1887. The other one that is more popular in Britan was written by William J. Kirkpatrick.

Leonardo's Robot


We just learned about Leonardo da Vinci's Paris Manuscripts.

Another one of his famous inventions was called Leonardo's Robot.

Some time around 1495, Leonardo da Vinci came up with the idea to make a mechanical knight, that could move around.
He made some sketches on how to make it using pulleys and cables that were inside metal armor.

He showed it off to some people in Milan, and by pulling on cables he could make it stand, sit, and move its arms and head.

His robot has been lost, but some people have followed his designs and made copies of what they think his looked like long ago.

Computers


We just learned about the Tire Code.

We've learned a whole lot about car engines work!

Let's learn a little about Computers.

When we think of computers, some people think of the laptop they use at home, or the bigger computer they use at work.
Other people might think of the really big computers sitting alone in rooms at buildings doing gigantic amounts of work for hundreds, thousands or even millions of people.

There are other things that are computers that people don't really call computers, like tablets or iPads, cell phones, or video game systems.
All of these things have computers inside them that make them work.
These days even things like cars, airplanes, TVs, and even things like Washers and Dryers have tiny computers in them!

The first computers made were made over 50 years ago and filled up entire rooms with all of their parts.
Things have gotten so small now that a computer the size of your fingernail could do more than that whole room of computers did.

Grey-Bellied Night Monkey


We just learned about the Black Capped Squirrel Monkey.

Another type of new world monkey is the Grey-Bellied Night Monkey.

Just like you would guess from their name, these monkeys stay up at night like an owl.
And just like an owl, they have really big eyes so they can try to see as much as they can in the dark.

These monkeys live only in some small parts of South America.
They only grow to be about 3 pounds, and they live in the trees eating fruit, vegetables, and small bugs.
