Soft Palate

We just learned about the Hard Palate on the roof of the mouth.

Another part of the mouth is the Soft Palate.

This is on the roof of your mouth, right at the back of your throat.
You can feel that this is soft, and under the skin are five different muscles that help you swallow.

They all have big long names, but they make sense if you understand what they are doing:

- Levator & Tensor veli palatini - Lift and tightens up the palate to block the back of the throat so food doesn't go up to your nose

- Palatoglossus & Palatopharyngeus - Use the palate muscles to pull on the back of your throat (pharynx) to close up the place where you breathe (trachea) and make sure the food goes down the esophagus where it's supposed to

- Musculus uvulae - Moves the uvula to help block food from going up your nose

Crenel

We just learned about the short wall on top of a castle called a Parapet.

Another part of a castle is the Crenel.

Sometimes people would have gaps in the parapet wall, so that they could attack their enemies with arrows or even throw rocks on them.

The gap or low spaces on the parapet walls are called the crenel, or embrasure.

Battle of the Milvan Bridge

We just learned about the Edict of Milan written in 313 AD by the emperor Constantine that it legal to be a Christian.

In the year 312 AD there was a big battle called the Battle of the Milvan Bridge in Ponte Milvio, Rome.

At that time Constantine was in a war with another emperor Maxentius.
Some time before the battle Constantine had a vision telling him to use the Chi-Ro symbol for his army, and he would win the battle with that as his sign.

We learned before that the chi-rho is the greek letters that look like X and P, and were for the Greek word for Christ, that started with those two letters.

Constantine put that symbol on the shields of his army, and beat Maxentius.

It was after he won that battle that he went back and wrote the Edict of Milan to make Christians free.

Taj Mahal

We just learned about the Jama Masjid.

Another famous Indian work of art is the Taj Mahal, built in 1632 AD in Agra, Uttar Pradesh, India.

The building is 240 feet tall, and the area where the building is covers 42 acres of land.
There is a mosque and a guest house, and fancy gardens.

It was made as a tomb for the wife of the emperor Shah Jahan.
He was so sad when his wife Mumtaz Mahal died that he wanted to make a very fancy place for her body to be put to rest.
The name Taj Mahal means "Crown of the Palaces".
It took about 20,000 people to make all the artwork, the buildings, gardens and towers to get it done.

Norwegian - His face is rough

We just learned in Norwegian her hands are soft is Hennes hender er myke.

To say his face is rough you would say Ansiktet hans er grovt.

The face - ansiktet - sounds like ah-n-sick-teh
his - hans - sounds like hah-n-z
is - er - sounds like eh-dr
rough - grovt - sounds like g-dro-v-t


So all together Ansiktet hans er grovt sounds like ah-n-sick-teh hah-n-z eh-dr g-dro-v-t.



(from: wikipedia - norwegian language)

Greek: Το πρόσωπό του είναι τραχύ (To prósopó tou eínai trachý)

Forensic Firearm Examination

We just learned about Ballistic Fingerprints.

Another type of science is Forensic Firearm Examination.

When guns are made, they are each given a special different code number called a "serial number".
No two guns have the same number, and when someone buys a gun they keep track of who owns which gun with which serial number.

This is done so that if a gun is used for a crime, the police can look at the serial number on the gun and figure out who owns the gun.

The serial number is printed right into the metal of the gun.
Sometimes people try to scrape off the metal where the serial number is, but police can use special electromagnets and chemicals to tell what the serial number was even if it has been scraped off.

Some guns these days are also being made to mark the serial number of the gun on the bullet when it is fired.
That way each bullet can be tracked down to who fired it if a crime is committed.

Irukandji Jellyfish

We just learned about the Immortal Jellyfish.

Another type of jellyfish is the Irukandji Jellyfish.

This is the smallest type of jelly, and also one of the most venomous ones in the world!

They can be as small as 0.2 inches, and as big as a little less than 1 inch.
Their tentacles can be as short as less than one inch, or as long as 3 feet.

If this type of jelly stings a person, after about 30 minutes they can have headaches, muscle pains, throwing up, or even a heart attack.
It can take a few hours to get better, or sometimes a day or even a few weeks!

Such a small jelly that pack such a dangerous sting can be scary to watch out for in the water.
These jellies mostly only live around Australia on the north side.
