Valve Port


We just learned about the valve Bonnet.

Another part of a valve is the Valve Port.

This is the part of the valve that lets water or gas in or out.
They can have as little as just two ports, but many valves have more.
Some valves even have up to 20 ports!

Simple two port valves are just open or closed.
Other valves with a lot of ports might have a few open and others closed depending on how it is set up.

Lappet


We just learned about the Nerve Net that is like a jellyfish's brain.

Another part of a jellyfish is the Lappet.

The circle shaped bell of a jellyfish is sometimes split up into parts by a small indent on the outside of the bell.
This little part where the bell dips toward the middle helps the jellyfish bell be able to flex and pull in and out so the jellyfish can swim.

Each of the parts of the outside of the bell between the indents is called a lappet.

Zonule of Zinn


We just learned about the Uvea.

Another part of the eye is the Zonule of Zinn.

This are the tiny little things like strings that go from the ciliary body to the lens.
Remember the lens is like the magnifying glass that changes shape so you can see far or close,
and the ciliary body is where the muscles are that help push and pull the lens to change it's shape.

It might sound like someone just wanted to come up with a funny name for a part of the body, but the word "zonule" means like tiny zone or tiny area, and the person who discovered this part of the body was named Johann Gottfried Zinn, so he named the area the Zonules of Zinn.

Sometimes it is also called Zinn's membrane, or the ciliary zonule, but Zonule of Zinn sounds the most fun.

Antarctica


We just learned about the Half Tower, and a whole lot of other types of castle Fortifications.

Let's learn about something else. The continent of Antarctica!

Even though we think of it as just a big chunk of frozen ice at the bottom of the earth, people have studied it and given names to all the parts of it from the east to the west.

There are even seas inside Antarctica, and hundreds of islands!

Some people even live down in Antarctica to study the ice and the climate.
There are some crazy animals down there too living on the land or even deep down in the cold sea.

We are trying to study it and learn more about it every year!

Nerve Net


We just learned about the Jellyfish Stomach.

Another part of a jellyfish's body is the Nerve Net.

In humans, our nervous system is our brain which is in charge of the rest of our body, and then our spinal cord and nerves that sends messages back and forth to the brain.

In most jellyfish, they have a nerve net which is kind of like the nerves we have all over, but without the spinal cord or a brain.

The nerves are all hooked together, and if a jellyfish senses something near by the nerve net can send messages all over it's body for the whole jellyfish to swim or try to pull in it's oral arms.
But it doesn't really have any thinking to it, it is just a very quick and simple reaction to a feeling.

It's kind of like if you touch something really hot, your hand very quickly pulls away without really thinking about it.
But if you were like a jellyfish, then your hand would touch something hot but your whole body would pull away, arms, legs and all!

Pentarchy


We just learned about the Baptism of Clovis I.

Another part of early Christianity is the Pentarchy.

We've already learned that the head of the big churches were called Bishops, and that the Bishop of the church in Rome is called the Pope.

In the old days there were 5 churches in the Roman empire that were seen as the most important:

Rome - in what is now Italy
Constantinople - in what is now Turkey, and renamed Istanbul
Alexandria - in what is now Egypt
Antioch - in what is now Turkey, renamed Antakya
Jerusalem - in what is now Israel

There were other churches, but the leaders of these churches were put in charge, so if there as disagreement between all of the many churches around these leaders would decide what to do.

It was the start of the churches really getting organized and turning into a really big group instead of a bunch of small churches spread around that argued with each other.

Jellyfish Stomach


We just learned about the Nematocysts.

Another part of a jellyfish is the Jellyfish Stomach.

We learned before about the oral arms that bring the food to the stomach, and the manubrium which is both the way a jellyfish eats and also gets rid of waste.

When a jellyfish gets food into it's stomach, it uses things called enzymes to slowly digest the food until it is all liquid, and then it sends it off to all the parts of the jellyfish's body.

After the good parts of the food are all used up by the jellyfish's body, the liquid is sent back to the jellyfish's stomach, and then pushed out of the manubrium so it is empty again.

The choroid is a layer in between the sclera and retina.
It helps give blood to the retina, helps hold things together, and also it is dark and helps make sure the retina picks up the light coming in from the pupil.

We just learned about the Leo and Attila.

Another part of early Christianity is the Baptism of Clovis I.

In the land we now call France, there were a lot of people who did not believe in God.
One of them was a very powerful king named Clovis I.

His wife was named Clotilde, and she grew up as a Christian.
When she married Clovis I she begged him to become a Christian, and after a while he finally agreed.

This helped spread Christianity through France, and because the King was a Christian it was safe for other people to talk about God.

There is still a statue of Clovis I being baptized in the city of Reims.

Another type of fortification is a Czech Hedgehog.

These were iron bars that were welded together in criss cross patterns and then put out on the ground to stop tanks.
The tanks couldn't drive over them, and they were too heavy to push around.
They also could not be knocked over, because even if they were tipped over they would still make the same kind of X star shape that tanks couldn't drive over.

They were called Czech Hedgehogs because they are spikey like a hedgehog, and they were first used in Czechoslovakia to protect them from German tanks during World War II.

Leo was a leader called a Bishop of the church in Rome, Italy.
Rome was usually thought of as the most important city of all, so the Bishop in Rome was usually the most important Bishop and got called the "Pope".

Attila the Hun was a warrior who was attacking all over the place, and in 452 AD came to Italy to try and take over.
The Emperor of Rome sent Pope Leo and a few other people to meet Attila and try to see if they could talk to him and make him not come attack Rome.

No one knows really what was said, but after meeting with Pope Leo, Attila packed up his troops and left Italy.

These are four big statues that used to be pillars that held up a roof for a building.
They are called atlantean figures, because they look kind of like sculptures of Atlas holding up the world that were found in Europe long ago.

The sculptures are in the town of Tula in the state of Hidalgo in Mexico.
No one knows for sure when they were built, but people think it was around 750 AD, by the Toltec people who lived there.

Another type of actuator or moving machine is a Cam.

A cam is a disc usually on a rotor that is spinning around.
The disc is mostly shaped like a circle, but it as a part that sticks out like a bump.
The circle disc is called the camp plate, disc cam or radial cam.

When the rotor spins around, that bump part of the cam can push down on something like a shaft or a pole.
Machines can use this to push those shafts down over and over again.
So every time the rotor spins around, it pushes the shaft down and then back up.

Some time around 430 AD, at the age of 16 a man named Patrick was captured by pirates from the island of Ireland.
He was taken back to Ireland, and was made a slave for 6 years.

Later on he escaped and went back to his home in Britain, and learned to be a Christian.
He knew the people in Ireland were not Christian, so he decided to go back there and tell people about Jesus.

When he went there, some people listened to him and became Christians, and other people did not like him and would put him in jail.
After many years of traveling around Ireland, he helped many people become Christians, and even after he died people still believed and spread the news.

When he died, because he did such a good thing they named him a Saint, so now they call him Saint Patrick.
The day of his death was March 17th, so on that day people celebrate Saint Patrick's day, and his life of service bringing news of God to the people of Ireland.

This is the language of the people of Russia, where over 250 million people speak the language.
A lot of the other countries near Russia also speak it, like Belarus, Estonia, Latvia, and a bunch of other countries.

Russia uses a different alphabet than English, using letters called Cyrillic.

There are some letters that look and sound almost the same, like A and T.
But there are some that are very different like the letter Я which sounds like "ya" or the letter Ш that sounds like "sh"
Let's learn how to say hello and goodbye in Russian!

Hi - Привет (privet) - Sounds like p-dee-v-yet
This is like saying Hi to your friends.

Hello - Здравствуй (Zdravstvuy) - Sounds like z-d-rah-v-st-voo-ee

Another type of thing used in machines is a Linear Actuator.

The word actuator really just means "mover" and there are lots of types of actuators out there.
Linear means moving in a straight line.

So a linear actuator is a type of machine that moves something in a straight line.
We learned before about rotors that spin around in circles in electric motors.
So this is different because it might be moving a rod up or down, back or forward but in a straight line.

Sometimes this is done by having a bolt or screw that has lines on it, and then a nut spinning around on the screw that makes the screw go up and down.
This is a roller screw linear actuator.

Aqueous Humour


We just learned about the Vitreous Body gel inside the eye.

Another part of the eye is the Aqueous Humour.

We know that the eye has different layers.
1 - On the very outside is the cornea, the clear part of the eye that you can touch with your finger.
2 - Then there is the pupil which is the hole letting light in, and the colored iris that helps control the size of the pupil.
3 - Behind those is the lens, which is like a magnifying glass that changes shape to help you focus.

In between those layers is some watery liquid that helps keep everything tightly held in place.
This is the Aqueous Humour, and you can think of it kind of like how a water balloon helps keeps the shape of the balloon.

Aqueous is because it is watery, and Humour means like a liquid.
So the name really means watery liquid.

Mariology


We just learned about the wise man Saint Augustine of Hippo.

Another part of early Christianity is Mariology.

This is the study of Mary the mother of Jesus, and exactly who she was and how she gave birth to Jesus.

In 431 AD, a bunch of people met at the city of Ephesus, which is now in Turkey.
They met together because there were people who did not agree on what Mary should be called, and what Jesus was like as a baby.

Some people thought she should be called "Theotokos" which means Mother of God, and others thought she should be called "Christotokos" which means Mother of Christ.

This might not seem like a big deal, but at the time people were still arguing about whether Jesus was a God and Man as one person, or whether he was like a person who also had a separate God personality living inside him.

About 250 different church leaders showed up to argue about this, and they decided she should be called Theotokos, Mother of God.

After this time there were a lot of other people talking about who Mary was, and what her life was like, so this became known as the study of Mariology.
