Superheater


We just learned about the steam locomotive Boiler.

Another part of a steam locomotive is the Superheater.

When the water gets heated up by the fire and goes through the fire tube boiler, it gets really hot and leaves the boiler as steam.
To make it even hotter, that hot steam is sent back into some other pipes to get heated even more.
This is called a superheater.

Superheated steam is better because it is more of a dry steam.
The dry steam holds the heat better, and helps the inside of the engine not get wet and rusty.

Sphynx Cat


We just learned about the Persian Cat.

Another type of cat is the Sphynx Cat.

This is a type of cat with no fur.
One funny thing about their skin is that even though they don't have fur their skin can be different colors, and if fur did grow from that skin it would be the same color as that skin..

Because they don't have fur they cat get cold, and they can either wear clothes made for them or they will go try and find warm places to curl up.

Neutrophil


We just learned about the Monocyte.

Another type of white blood cell is a Neutrophil, also called a neutrocyte or heterophil.

We've learned about 2 other types of white blood cells:
- lymphocytes - that help kill off bad diseases using T, B or NK cells.
- monocytes - that help fight off infections and clean up garbage in the body.

The neutrophils are a lot like the monocytes, where their job is to go fight off bad germs and dirt that cause infections and make you sick.
These are the first line of defense for your body when there is an infection, they are like the emergency workers that rush to the scene to help out.


There are more neutrophils than any other type of white blood cell, and the human body makes about 100 billion neutrophils every day.

One of the only differences between monoctyes and neutrophils is that when a monocyte fights off an infection or disease they leave behind some clues about what kind of disease it might be.
These clues help the super powerful lymphocytes come in if there is a bad disease that needs to be killed off.

Sistine Chapel


We just learned about the Gutenberg Bible.

Another part of early Christianity is the Sistine Chapel.

In 1473 AD the builder Baccio Pontelli tore down an old chapel that was falling over and built a new big chapel for the pope at the time called Pope Sixtus IV.
It was called the "Cappella Magna" or Great Chapel, it was the new home for the Pope and was full of many famous works of art by artists like Boticelli and Michelangelo.
The name was changed to the Sistine Chapel for the name of Pope Sixtus.

When the church is trying to choose a new pope, they put a chimney up on the roof.
If all of the church leaders agree on the pope then they throw all their ballots in the fireplace and it makes white smoke out of the top of the chimney, telling everyone that there is a new pope.
If they can not agree, then they put some other things in the fireplace to make black smoke come out of the chimney to tell everyone they have not made up their minds yet.

Monocyte


We just learned about the kind of white blood cell called a lymphocyte, and the kind of lymphocyte called the B Cell.

There are other kinds of white blood cells, like one called the Monocyte.

These white blood cells are bigger than their cousins the lymphocytes, and their job is to go around cleaning up dirty things like infections in the body.

When they see something like dirt or infection they turn into something else called a macrophage and they wrap themselves around the bad stuff, almost like they are eating it, and they destroy the unhealthy bad stuff.

They are different from the lymphocytes because lymphocytes are really for targeting specific diseases or viruses, and monocytes are really more like cleaning up all the dirty garbage and fighting off infections.

So if your skin gets cut and you don't wash it off and keep it clean, you can get dirt and germs in your body.
The monocytes help fight off the bad stuff that comes from the dirt and germs if it gets infected.

Gutenberg Bible


We just learned about the Devshirme.

Another part of early Christianity was the Gutenberg Bible.

Long ago when people wanted to make a copy of the Bible they had to write it out by hand.
It was not very easy to make paper, ink or pens, so it took a long time, and each copy looked very different depending on who was writing it and what the paper or pen looked like.

Around 1450 people were using something called a Printing Press that was like a big stamp with a roller of paper that could print a lot of copies quickly.

In Germany a man named Johannes Gutenberg used the printing press to make about 150 copies of the Bible, and send them around Germany.
This started a big change in the world of Christianity because a lot more people could read the actual words in the Bible and learn for themselves about God and Jesus.

In your body you have the living cells that make up your body or even bad diseases, and then you have a lot of other liquid floating around that is not made up of cells, just liquid.

The T Cells and NK Cells work on looking at the cells, killing bad ones and letting good ones live.

The B Cells work on the liquid that is flowing around the cells in your body.
If they find anything that looks bad, they let out these things called antibodies that stick to the bad disease and tell the body that this bad cell needs to be killed.

It is 11,000 square miles and has about 2.8 million people living there.
Tirana is the capital city and biggest city in the country.

Because of where it is on the map, it has some very cold weather up in the mountains, and very warm weather in the southern parts on the sea.

Devshirme


We just learned about the Fall of Constantinople.

Another part of early Christianity was Devshirme.

Many times in history Christians and Hebrews were not treated very well.
In Egypt during Moses time they were slaves, and when Jesus was alive they were not treated well by the Roman empire.
When Emperor Constantine came around, things were very good for Christians for about 1,000 years.

After the fall of Constantinople, some Christians started being mistreated again by the people that were the new Ottoman rulers in the east.

One sad thing that happened is that Christian boys from the ages of 8 to 20 were taken away from their parents and made to work in the army for the Ottomans.

They were not killed or tortured, but they were told that they could not be Christian anymore.
These kids were put into school and could even become rulers in the land, like the Grand Vizier the second most powerful person in a land.

Even though they weren't killed many families were very sad that their kids were taken away.

Another famous American sculpture is Prometheus by Paul Manship in New York in 1934.

In the 1920s in America, some sculptors started making statues that were a lot like the very old Greek statues in the art style called Classical Art.

Paul Manship was born in Minnesota in 1885 and grew up learning to be an artist.
When he was 24 he won an art competition and got a trip to to go Rome Italy.
While he was there he really learned to like the old Classical style, and when he came back to America he started making statues like he saw in Europe.

The Prometheus sculpture is made of bronze, and it is in New York at the famous Rockefeller Center.
It is 18 feet tall and weighs 8 tons.
Prometheus is a Titan from Greek mythology who brought fire to people by stealing it from the sun.
In this sculpture it has a big ring around Prometheus that he is falling through toward the earth.

On the wall behind the statue are the words: "Prometheus, teacher in every art, brought the fire that hath proved to mortals a means to mighty ends."

Another type of lymphocyte is T Cells.

We are looking at:
- the type of blood cells called white blood cells,
- the type of white blood cells called lymphocytes
- the type of lymphocytes called T Cells.

These cells are called T Cells because they are usually found in a part of the body called the thymus, which is right in the middle of your chest behind your sternum.

All white blood cells are made in the bone marrow, but after these T Cells leave the bone marrow they go to the thymus.

T Cells are kind of like NK Cells as they go kill bad viruses that attack your body, but the T Cells are special because they are made to only attack certain types of viruses, where as the NK Cells attack everything.

When the T Cells go to the thymus, the thymus sorts them out and figures out which ones are set up to fight the right kinds of viruses that the body wants to fight, and then if a T Cell is not needed it is thrown away.

The T Cells are sort of like specialized attack soldiers waiting for certain viruses to show up and then they attack.

Another part of early Christianity was the Fall of Constantinople.

Back in the year 313 the emperor Constantine made himself a home city of Constantinople, in eastern Europe.
For a long time it was the strongest city in the area, and was the head of the Roman empire.

Later on the eastern and western parts of Europe started arguing over how the church should be run, and about whether the head of the church should be in Rome, Paris or Constaninople.

When that happened, and Constantinople had other problems like fighting off plagues, it was not the strongest city anymore.

In the middle eastern countries the Ottoman Empire was getting very strong, and so they started a war to take over Constantinople.
The western European countries did not come to help Constantinople, so the Ottomans took over Constantinople easily, and also because they were using gunpowder and cannons.

It wasn't made just for Native Americans, but for the whole world.

The statue is 38 feet high, and made of onyx.
It is on top of a moving base at the bottom that slowly spins the statue around about 1 time every few hours.

Carl Milles was born in Sweden in 1875, and became a famous artist working there until he was 56.

These cells float around in the body, and if they find a cell that doesn't look like it's supposed to be part of the body then it lets out some chemicals called cytokines that will destroy the bad cell.

The bad cells might be like a tumor, an infection or a virus, and when the NK Cell releases it's cytokins and the bad cell will be destroyed.

Even though it is an island, the rock part of the island is below the water, and on top of the rock is a big bunch of ice that makes up the island.
If all of the ice melted, the island would be under water.

Joan of Arc


We just learned about the Avignon Papacy.

Another part of early Christianity is the famous French person Joan of Arc.

She was born in France in 1412, while there was a war going on between France and England.

When she was 13 she said that she had a vision of some Christian saints, who told her she needed to go help King Charles VII of France to win the war.

At first no one believed her, but she begged over and over again to go see the king.

When she was 17 she finally got to see the king, and he let her go to some of the battles and try to help out.
Wherever she was at the French won their battles easily, so people started believing that she was a sign from God that they could win the war.

She wasn't really a fighter who carried a sword, she usually had a banner that she waved around to try and help get all the French soldiers excited about winning.

When she was 19 she was captured by the English soldiers, and they had a trial where they said she was bad and wasn't talking to Christian saints but was working for the devil, and they had her killed.

Years later the French people said that trial was not fair and said she was innocent, and the church leaders agreed so she became a Christian hero Saint Joan of Arc.

Her story is very famous in France and people have even found the house where she grew up and turned it into a museum.

We just learned about the sculpture of Richard Yates by Albin Polasek .

Another famous work of American art is the sculpture of Georgia O'Keefe made by Gaston Lachaise in 1927.

Lachaise was born in 1882 in France, where he grew up learning how to be a sculptor.
He met an American woman named Isabel and fell in love with her, so when he was about 20 years old he moved to America with her and they got married.

Connecting Rod


We just learned about the Coupling Rod that hooks all the wheels together.

Another part of a steam locomotive is the Connecting Rod.

Remember that we learned about how steam pressure works with a steam cylinder to push and pull a piece of metal in a tube called a piston.

The piston is hooked up to the connecting rod, which takes that forward and back pushing an pulling and makes it into a circular push and pull to spin the locomotive's wheel around.
