White Spotted Jellyfish

We just learned about the Lobed Comb Jellyfish that lights up like a rainbow.

Another type of jellyfish is the White Spotted Jellyfish, also called the floating bell, Australian spotted jellyfish, or phyllorhiza punctata.

This type of jelly started out living in warm water in the Pacific ocean by Australia and Japan, but has now been found all the way over by California, and even in the Gulf of Mexico.
It grows to about 20 inches wide, and does have a sting but it doesn't really hurt humans.

They swim in large groups with other white spotted jellies, and because of this they can be harmful to other life in the ocean.
In their groups they swim along and eat all of the tiny little things like zooplankton, or eggs of crabs, shrimp or fish.
They also clog up the boat motors and cause problems with ships on the sea.

Lips

We just learned about the part on the roof of the mouth called the Palatine Raphe.

Another part of the mouth is the Lips.
The big long names for the upper and lower lips are the Labium superius oris and "Labium inferius oris.
Labium means lip, superius and inferius are for upper and lower, and then oris is for the face, near the mouth.

The lips have no sweat glands, and can not grow hair.
Skin on the lips is softer than the face skin.

Most of the skin on the face has 16 layers, but the skin on the lips only has about 4 layers.
It also doesn't have the same coloring cells as the face does, so you can see right through the top skin and see the blood vessels underneath it.
That's why the lips are pink or red, because of the blood vessels underneath.

There are a whole bunch of muscles for the lips that we learned about a while ago:
Upper lip: levator labii superioris and levator anguli oris
Lower lip: depressor anguli oris, depressor labii inferioris, mentalis

Lips are used to open and close for food, to help make sounds when we talk, and also to kiss!
Because lips are on the human face, people try very hard to make their lips look nice, sometimes using makeup or lip gloss, and sometimes even having surgery to make their lips look bigger.

The lips are very important to keep healthy, which is why there are things like lip balm to protect them.
Healthy lips help protect the mouth from the outside, and keep a healthy mouth!

Curtain Wall

We just learned about the hole in a castle wall called the Machicolation.

Another part of a castle is a Curtain Wall.

This is another wall that goes around the main castle, to help protect the castle inside the wall.

Its name makes sense because it's like a big curtain going around the outside of the castle.

Church of the Pater Noster

We just learned about the Church of the Nativity in Bethlehem where Jesus was born.

Another part of early Christian history is the Church of the Pater Noster in Jerusalem.

In the Bible there was a place called the Mount of Olives, where Jesus appeared to the disciples and then ascended into heaven.

When the emperor Constantine sent his mother Helena out to find some of the important places in Christianity, she came to this place and made a church where the Mount of Olives was.

It's called Church of the Pater Noster because "pater" means father and "noster" means our.
In a cave below the Mount of Olives is where people believe Jesus taught his disciples the Lord's Prayer, which starts with the words "Our Father".

Pisa Griffin

We just learned about the Trà Kiệu Pedestal from the ancient Champa kingdom.

Another famous sculpture is the Pisa Griffin, made around 1000 AD somewhere in Spain.

It is about 3 feet tall, and is the largest Islamic metal sculpture ever found.
It has carvings on it, and some holes.
Some people think the holes were used to make it into a fountain, and others think maybe the holes were to make sounds like a horn.

The sculpture is in Pisa, Italy now, and people think it was taken as a treasure from war long ago when some people from Italy battled some Islamic people in Spain.

Forensic Dentistry

We just learned about how scientists can use Forensic Botany to figure out what kind of plants were around during a crime.

Another part of forensic science is Forensic Dentistry.

Sometimes after a crime has been committed, scientists will look at teeth to figure out what really happened.

If there was a fight between two people and one person bit the other person, they can look at the bite mark and try to match it up to the other person's teeth!

There also might be a skeleton that was found from a long time ago, and people aren't sure who it was.
If that person ever went to the dentist and had molds made of their teeth or x-rays of them, they can try to match it up and see who it was.

The teeth can also tell a scientist how old a person was when they died.
This can even be helpful for people that died hundreds of years ago, when people are digging out ancient pyramids, castles or finding cavemen!
