Constantine the Great

We just learned about the Battle of Milvan Bridge where Emperor Constantine saw a vision of God.

The Emperor Constantine was the first emperor to become a Christian.
He tried to bring all of Rome together and be the only emperor, and also changed the laws so people could worship however they wanted.

During his time he also had many battles, and used the Chi-Rho symbol on his army, and he believed it was God helping lead him into battle.

Because he helped Christianity and was the first Christian emperor, he later on was called Constantine the Great.

Under Constantine's rule, the Roman empire went all the way up to England, Spain, France, all the way over to Greece, Turkey and Israel, and even covered the northern part of Africa, like Egypt.

Banteay Srei Sculptures

We just learned about the Taj Mahal.

Anther place with a lot of history in sculpture is the country of Cambodia.
This is in southeast Asia, and long ago was part of a land called the Khmer empire.

In the 10th century, there was a temple called the Banteay Srei built in the city of Angkor.
It has many stone cut sculptures all over it, made mostly from red sandstone that was very easy to cut.

Forensic Anthropology

We just learned about how scientists can look at guns with Forensic Firearm Examination to see who committed a crime.

Another part of forensic science is Forensic Anthropology.

This is the science of looking at the bones of a person and trying to figure out what happened.
Sometimes this is used in archeology for bones that are hundreds or thousands of years old.
Other times it can be used by police when they find some bones, to try and figure out who the person was.

Scientists can look at teeth to see how old the person was, or the length of their arm or leg bones, or even the size of their skull.

They can even look at the hip bones of a person to see if they were a man or a woman.
Sometimes this helps solve a crime if they find an old skeleton, and they don't know who the person was when they were alive.
If they figure out who it was, they can look for marks on the bones, to maybe tell how they died.
They can also look at the teeth, and sometimes match them up with x-rays from a dentist office to see if they can figure out who it was.

It might seem a little scary or creepy, but by using science with old bones we can solve crimes and make sure the bad guys don't get away!

Atolla Jellyfish

We just learned about the Irukandji Jellyfish.

Another type of jellyfish is the Atolla Jellyfish, also called the Atolla wyvillei or Coronate medusa.

The atolla jellyfish live very deep in the ocean, from 1,000 to 4,000 meters deep.

These are very tiny jellyfish, only growing about 170 milimeters wide.
They have about 20 tentacles floating off of their bell, and then one really long one that hangs out trying to trap prey to eat.

Because these jellies are so small, they get eaten a lot by other animals.
When they think they are in danger, they are able to flash their body like a blinking blue light.

When this happens, sometimes a bigger animal will come along and eat the smaller animal that is trying to eat the jelly.
This gets the jelly the nickname of "Alarm Jelly" because it's alarm goes off when it gets scared.

Scientists have copied this flashing blue light and used it to try and get other big deep sea animals to come check it out.

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.
