A gorilla can grow to be 500 lbs and about 6 feet tall.
They have very long arms, and their arm span can be voer 8 feet long.
Most gorillas live to be over 35 years, and the oldest gorilla ever was 60 years old.
Gorillas can walk on their feet, but usually they do what is called knuckle walking, meaning they walk on all fours but using the knuckles of their handles.
They sleep in nests on the ground made of branches, and they eat leaves, fruits or sometimes bugs.
Grownup male gorillas get silvery grey fur on their back, which is where they get the knickname of silverbacks.
A family of gorillas is called a troop, and is usually made up of one adult male, a few adult females, and a bunch of young gorillas.
Young male gorillas are called blackbacks because they don't have the grey fur yet.
Once they get older they leave the troop and go try to find female gorillas to start their own troop.
Male gorillas help keep the troop safe from other gorillas and other animals that might attack the troop.
All gorillas live in Africa, and there are two different main types of gorillas, eastern gorillas and western gorillas.
There are four types gorillas: Western lowland gorillas, cross river gorillas, mountain gorillas and eastern lowland gorillas.
Most of these gorillas look a lot alike, but some have longer fur, red fur, smaller bodies or longer faces.
Gorillas are very smart and sometimes use tools like rocks or sticks.
They talk to each other using hoots, grunts, barks, screams and roars.
Some gorillas in captivity have even been known to learn sign language.
Let's learn a little about the country of Hungary!
This is a country in the middle of Europe that borders Slovakia, Ukraine, Romania, Serbia, Croatia, Slovenia and Austria.
It is about 36,000 square miles, and about 10 million people live there.
The language of Hungary is Hungarian, and the name of the country comes from the Hun people who were the first to take over the land.
Another part of early Christianity was the French Wars of Religion.
In the 1500s, the Catholic church and another group of Christians called Huguenots fought each other for over 30 years.
It was a very bad war, and about 3 million people died.
The Huguenots and the Catholics just did not agree on what the Bible said was the right way to believe, and because there were princes, kings and queens fighting about this it turned into a war.
Because the war was so bad, a lot of people from around the world started looking at Catholics as not very nice, and other people joined the protestant reformation.
Another famous American sculpture is La Grande Vitesse by Alexander Calders Calders made in 1969 in Grand Rapids, Michigan.
Calder was born in 1898 in Pennsylvania. He was the third famous artist named Alexander Calder, after his father and grandfather who were both famous artists named Alexander.
Calder was famous for making mobiles, sculptures hanging from strings that would spin slowly with the air, and also "stabiles" that looked like they were moving but were big solid sculptures.
His sculpture La Grande Vitesse which means The Great Swiftness, or The Grand Rapids.
The sculpture is famous in the town of Grand Rapids, is nicknamed The Calder, and they even use it in the logo for the city.
We just learned about the Coupling on a locomotive.
Let's learn a little more about how most cars work.
The biggest most important part of the car is the Engine Block, sometimes called the cylinder block under the hood.
This is a big solid piece of metal in the car.
The engine block does not move, but it has parts hooked into it that move to help make the car go.
Because the moving engine is so powerful, this block has to be made in a cast or mold.
That means they take hot liquid metal, pour it into something to hold it's shape and then let it cool.
After it is cooled the block is very strong and can hold onto other pieces that are moving very fast and pushing very hard.
One type of primate is the Chimpanzee, also called the common chimpanzee or robust chimpanzee.
This type of primate is the most like a human of any other primate.
Their skeletons, brains, and bodies are the most alike humans, and the way they act toward each other is a lot like humans can.
Chimpanzees are usually about 150 pounds and about 4 feet tall.
There is another type of chimpanzee called the "bonobo" that is a lot like the common chimpanzee, but a little smaller.
Chimpanzees have dark hair all over their bodies, except for their face, the inside of their hands and the bottoms of their feet.
With hands like humans, chimps can climb trees, and even use sticks and rocks like tools.
Their feet are more like a human hand, which helps them climbing trees.
These primates hang around in all different types of groups.
Sometimes there are groups of males that go hunting together, sometimes groups of females working together to help raise babies, and sometimes groups of males, females, babies and old chimps all staying together.
They live in forests, climb trees, are covered in fur and make loud screeching sounds, but these primates are the closest things to a cousin that humans have in the animal kingdom.
