We just learned about the Cylinder in the engine block.
Another part of a car's engine block is the Cylinder Head.
The engine block cylinders are the piece that holds that pistons that move up and down.
On top of that cylinder part is the cylinder head.
This is the big metal piece that goes on top and closes in the pistons.
It also has other parts that let in fuel and take out the wasted exhaust from the piston.
The orangutans have orangey red colored fur, but their name doesn't come from their fur color.
In Malay the word "orang" means person, and "hutan" means forest.
Because these apes looked like furry people walking around the forest, long ago people actually thought they were just really hairy people!
Orangutans live most of their lives climbing around in trees and eating fruit.
They have really long arms which helps them climb, and they even make nests in trees to sleep in at night.
These animals are very smart, and have learned to use tools to get food.
Some orangutans like to eat bugs, honey or bark, and they will take a stick that they sharpened with their teeth to open up tree bark or to crack open fruit to eat the inside.
If an orangutan really likes the tool that it used, it will save it and collect other tools in their own little toolbox.
When orangutan males grow up, their face changes a lot, and grows to be flat and wide.
Orangutans don't live in family groups like chimpanzees or gorillas, they mostly live alone except for young ones that live with their mother for a few years.
There are three main different types of orangutans that live in different parts of the world and look a little different: Bornean, Sumatran, Tapanuli.
All wild orangutans live on the island countries of Borneo and Indonesia.
We just learned about the Epitope that the body looks at to find diseases.
Even though we've learned about all of the amazing things the human body does to fight off pathogens or diseases, sometimes the human body still gets sick.
Sometimes things go wrong with the blood cells we've learned about, with something called Blood Cancer.
Cancer is a disease that can affect any type of the body, from the bone to skin to brain.
Blood cancer has three different kinds: Leukemia, lymphoma, myeloma.
One of the ways that people test for these diseases is counting the number of each of the types of blood cells, from leukoctyes to lymphocytes to B cells.
The human body is supposed to have a certain number of each type of cells, and if the count is wrong then it can tell doctors something is wrong.
Let's learn a little about the country of Kazakhstan!
This country borders Russia, China, Kyrgyzstan, Uzbekistan and Turkmenistan.
It is over a million square miles, and is the biggest country in the world that does not border any of the oceans.
Even though it is a very big country, there are only 18 million people living there.
The flag of Kazakhstan is light blue for the Turkic people, sky and water.
There is a yellow sun for wealth, and a yellow eagle is for freedom.
The left side has a pattern that is used a lot in Kazakhstan culture.
To eat in Kazakhstan you might have beshbarmak, which is boiled meat with noodles and onion sauce.
The name means "five fingers" because in the old days when nomads traveled around they would eat this with their hands.
To visit in Kazakhstan you might go to the Khan Shatyr Entertainment Center.
This place is covered by a mesh tent made of wires that goes up about 500 feet.
Under the tent is a big place where a lot of people can have fun playing sports, shopping, going to a beach resort or boating down a river!

In the southern part of the country is a spaceport used for launches into outer space.
It's the oldest spaceport in the world, and was the place that the Sputnik 1 and Vostok 1 rockets launched from.

Another part of early Christianity is Believer's Baptism.
After some other people started to change the way they worshipped God to be different than the Catholic church, another group of people believed that people should be baptised as adults, not as babies.
Some people in the church believed that baptism was for babies to be brought into God's family when they were little, and then the church would raise them as Christians until they were old enough to take on responsibility of church for themselves.
Other people believed that since babies could not make the choice that they should have to wait until they were older to make the decision to be baptised themselves.
Because people disagreed about this, some of the early people called anabaptists who thought this way were killed by church leaders who thought they were being bad.
Today there are other religions who baptise as adults, like Baptists, or Amish
and other religions that baptsie as babies like Catholics or Lutherans.
Another famous American sculpture is S, metal made by John Chamberlain in 1959 in Washington DC.
Chamberlain was born in Indiana and went to art school in Chicago.
He was most famous for making sculptures that were out of metal, mostly using rusted old car parts.
Some people thought he was one of the best makers of abstract art out there, and his art was put into museums next to other famous artists like Picasso.
One problem that he had was that because his art was made of old rusted car parts, not everyone knew it was art.
At a museum one time someone thought his artwork was just junk, so they took it and threw it away.
