Hydraulic Cylinder


We just learned about Hydraulics, using water to move things.

Another part of hydraulics is a Hydraulic Cylinder.

This is a tube that is filled with liquid like oil, and a special motor pushes more oil into the cylinder which pushes something like a big metal rod out of the tube.

Clouded Leopard


We just learned about the Snow Leopard.

Another type of cat is the Clouded Leopard.

This cat lives in the himalayan mountains in Asia near China.
There are not many of these cats left, with only about 10,000 of them around.
The clouded leopard and sunda clouded leopard are actually two different types of cats, but are very difficult to tell apart other than where they live, as the sunda lives in Borneo and Sumatra.

These cats have dark grey fur, with black and dark blotched spots on them.
They have black ears and some stripes on their face and shoulders.

The clouded leopards are much smaller than other leopards, weighing only about 50 pounds, and being less than 4 feet long.

Because these cats live in the mountains, they are great climbers.
They can even climb down a tree head first, hanging on with their back paws wrapped around the tree.
These cats are also great jumpers, and can easily jump over 4 feet high.

Depth Perception


We just learned about Rapid Eye Movement.

Another part of how eyes work is Depth Perception.

Because humans have two eyes that are set apart from each other, they can look at the world and tell if something is close and if something is far away.

With just one eye it is very hard to tell that, but because two eyes are looking at something from different angles, the human brain can use those two different pictures and figure out if something is close or far.

Roald Amundsen


We just learned about Adriene de Gerlache, the first person to explore Antarctica.

Another famous explorer of Antarctica was Roald Amundsen, from Norway.

Amundsen was one of the people who went with Gerlache on the first trip to Antarctica, so he had some idea what to expect down there.
He worked with a famous explorer named Nansen to get a special boat called Fram which was made special so that it would not get stuck in the ice.

Amundsen at first was planning to go to the North pole, but right at the same time the news came in that someone else had just made it to the North pole so he changed his plans.

He started his trip to the South pole starting in the year 1910 AD.
Unlike some other explorers, Amundsen knew that sled dogs were great for traveling in the cold, so he got 100 sled dogs from Greenland.
He knew how cold it got in Antarctica, so he had boots and clothes specially made from seal, reindeer and wolf skins as they were natural protection against the cold.
They made special long skis and long sleds to be used on the glaciers, and big strong tents that could hold up to the wind and cold.

Amundsen knew that people could get sick if they did not eat right, so he made sure they planned to eat lots of seal meat and fruits.
He knew they could go crazy from the cold and darkness, so he brought some wine, some music instruments and records, and thousands of books to give people something to do.

When he landed in the south part of Antarctica by the Ross Ice shelf, they set up a special camp called "Framheim" which meant the home for Fram, their boat.
They built a big shed there to be safe from the cold, and then started making trips out toward the south pole.
Taking the sled dogs, they would travel for about 15 miles and then put up a tent with some supplies called a depot, and then go back.
Every time they would go along, stop at a depot for supplies and then go a little further.
Eventually it was getting too close to winter and they had to stop and wait for months for it to stop.

At the same time that Amundsen was there, some other explorers from Britain were there too, so it was a big race to get there.
The British were using motorized sleds instead of dogs.

In 1911 after being at the pole for eight months, they set out on their trip to the South pole with five people, four sleds and 52 dogs.
They had a very tough time, and lost 40 of their dogs, but finally made it to the South pole and put up their tent.
The name they gave to their tent was Polheim, meaning "Home at the Pole", and they left supplies for any other travelers that might make it there.

They went back to their ship and went home to Norway where they were made heroes and given the Norwegian South Pole medal Sydpolsmedaljen.

Cyrillic Script


We just learned about the Christianity in Bulgaria.

Another part of early Christianity is the Cyrillic Script.

We learned before about the Glagolitic Alphabet made by the monks Cyril and Methodius.

The schools in the country of Bulgaria worked together to make a new writing language that would be easy for people in the area to read.
They wanted people to be able to read and have church services in their local language instead of Greek.

The Cyrillic Script is used today by over 250 million people in several languages like Russian or Ukranian.

Standing Lincoln - Augustus Saint-Gaudens


We just learned about the statue of Charles Sumner by Anne Whitney.

Another famous American statue is Standing Lincoln made by Augustus Saint-Gaudens in 1887 in Chicago.

Saint-Gaudens was born in Ireland in 1848, but moved to New York when he was a baby.
Growing up he learned about sculpture, and when he was 19 he moved to Paris and Rome to learn more about art.

He came back to American and in his adult life became very famous for making sculptors of Civil War heroes like Abraham Lincoln or Robert Gould Shaw.

His Standing Lincoln statue of Abraham Lincoln in Chicago is one of his most famous.
It is sometimes called "Abraham Lincoln: The Man" and is 12 feet tall made of bronze.

Many people say it is the most important sculpture of Lincoln from this time, and shows him rising from a chair about to give a speech.
Saint-Gaudens was at Lincoln's inauguration when he became president, and also at his funeral.
He really liked Lincoln a lot, and tried his best to make a statue that would stand for a long time honoring Lincoln.

It was such a famous statue in Chicago that famous people like Jane Addams would walk to the statue sometimes to look at it and be inspired by Lincoln's life.

Russian - We are surprised


We just learned that in Russian I am happy is Я счастлив (ya shastliv),
you are sad is Ты грустный (Ty grustnyy),
he is angry is Он сердится (On serditsya),
and they are excited is Они взволнованы (Oni vzvolnovany).

Let's learn how to say We are surprised.

Мы удивлены (My udivleny)

We can break it up into two words:

We - Мы (My) - Sounds like Moo 文A
are surprised - удивлены (udivleny) - Sounds like oo-dee-v-lay-n-ee 文A

So all together Мы удивлены sounds like Moo oo-dee-v-lay-n-ee.
