Tabby Cat

We just learned about the Calico Cat.

Another type of cat is a Tabby Cat.

Just like the calico, tabby isn't a type of cat breed, it is just a type of fur style that can be on just about any breed of domestic cat.

A tabby cat is any cat that has an M shaped mark on their forehead, and stripes on its body.

NK Cells

We just learned about the type of white blood cell called a Lymphocyte.

There are a few types of lymphocytes, like the NK Cells, also called Natural Killer Cells or large granular lymphocytes (LGL).

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.
Because these LGLs kill other bad cells they are called natural killers.

Berkner Island

We just learned about the largest island in Antarctica, Alexander Island.

The second largest island is Berkner Island.

This island is about 200 miles by 100 miles, and 17,000 square miles, bigger than the US state of Maryland.

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.

During the cold parts of the year the island is surrounded by ice, so it doesn't always look like an island.

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.

Georgia O'Keefe - Gaston Lachaise

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.

He was mostly famous for making sculptures of women that looked very big and powerful, like a force of nature.
Most people made sculptures of women that were very small and delicate, so this different way of making sculptures of women was seen as a way to give power to women who were seen by some people as weak.

He also made sculptures of famous people like Georgia O'Keefe.
She was a famous American artist, who some people called the Mother of American modernism.

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.
