Poppet Valve

We just learned about the Ball Valve.

Another type of valve is the Poppet Valve.

This is a valve that is usually used to open and close for gas to come through.

In a car's engine there are valves used to help the fuel come in, and after it makes a big explosion there are valves to let the burnt up air out.

We just learned about Cats.

The big cat known as the king of the jungle is the Lion.

Lions mostly live in Africa, but there are also some in the Middle East and Europe.

Lions are big cats that are part of the "Felidae" family.
The male lions have a big mane, and all lions have a hairy fluff of fur at the end of their tails.
They are usually 6 or 7 feet long, and they can weigh over 300 pounds!

Lions live together in a family that is called a "pride".
A pride is usually a few grown up males, then some females and little lion cubs.
When the little lion cubs are about 3 years old, the boy lions are sent off to live on their own, and the girl lions stay with the pride.
When boy lions are out by themselves, sometimes they will group together with a few other boy lions until they find a home where they join a new pride as a grown up male lion.

Lions can make a lot of sounds like purring and meowing, but they are best known for the lion's roar.
It is so loud that it can be heard up to 5 miles away.

There is one type of lion called a white lion, that has white or very light colored fur.

Central Retinal Vein

We just learned about the Central Retinal Artery.

Another part of the eye is the Central Retinal Vein.

The artery brings blood to the eye, and this vein in the back of the eye then takes that deoxygenated used up blood and brings it back to the heart.

Filchner-Ronne Ice Shelf

We just learned about the Ross Ice Shelf.

Another part of Antarctica is the Filchner-Ronne Ice Shelf.

This shelf is about 430,000 square kilometers, which is bigger than the state of California.
It is about 600 meters deep, and below the shelf the water goes down another 1,400 meters.

In 1998 an iceberg named A38 split off from the ice shelf that was over 22,000 square kilometers.

We just learned about the Muslim Conflict.

Another part of early Christianity is Icons.

In the old times of the church, people thought it was bad to use pictures of crosses, or even pictures of Jesus, Mary or any of the old leaders of the church.

The paintings were known as icons.

Because God said not to worship any idols, they felt that putting up artwork of something Christian was like worshipping an idol.

Later on people argued that having these paintings around was good because it helped people think about God and Jesus.

Michigan Soldiers' and Sailors' Monument - Randolph Rogers

We just learned about the sculpture The Willing Captive - Chauncey Ives.

Another famous work of American sculpture is the Michigan Soldiers' and Sailors' Monument by Randolph Rogers in Detroit Michigan, 1867.

Rogers was born in New York, but grew up in Ann Arbor Michigan.
He started off doing most of his sculpture in wood, and then later worked with marble.

When he was about 40 years old he moved to New York City and then Florence Italy to study sculpture.
He didn't really like working with marble, so he would always make his statues out of something else like wood, and then have other marble sculptors make a copy of it in marble for him.

His civil war monument in Detroit is octagon shaped.
On top is a sculpture of a heroic woman called Michigania, or Victory holding a sword and shield.
There are four male sculptures for the Navy, Infantry, Cavalry and Artillery of the Civil War.
Four female sculptures are for Victory, History, Emancipation and Union.
By the bottom are eagles with raised wings, and four plaques with Union generals Lincoln, Grant, Sherman and Farragut.
