Windings

We just learned about the Stator in an electric motor.

Another part of an electric motor is the Windings.

These are the metal wires that are wrapped around the stator or the rotor.
They are wrapped in loops around and around, and when electricity goes through these wires it creates something called an electric or magnetic field that can spin the rotor around.

This works kind of like magnets that can move metal without even touching them.

Jellyfish Epidermis

We just learned about the Jellyfish Bell.

Another part of the jellyfish is the Epidermis.

The epidermis is the skin on the outside of the bell.
Just like humans, jellyfish have skin, and their epidermis has a bunch of nerves in it called a "nerve net".

This nerve net helps them feel movement in the water and tell their body where to try and swim to get food.

Optic Nerve

We just learned about the Lens in the eye that helps focus light for us to see.

Another part of the eye is the Optic Nerve.

We learned before about the retina in the back of the eye that takes the light from the eye and turns it into signals that the brain can understand.

The retina is connected to a big long nerve called the optic nerve.

This nerve takes the signals from the retina and carries them all the way to the back of the brain, to the part of the brain called the occipital lobe where the signals from the eyes get turned into pictures for the brain to understand.

Meurtrière

We just learned about the Battery Tower in a castle.

Another type of fortification is the Meurtrière, also called a murder hole.

These were holes in the ceiling where people from above could throw rocks, shoot arrows or pour hot water on attackers to keep them out of the castle.

The Great Persecution - Persia

We just learned about the city of Constantinople.

Another part of early Christianity is the The Great Persecution - Persia.

The great persecution is the name for when Christians were killed or put in jail for being Christian.
It had happened in Rome a long time ago, until Constantine took over.

After he created the city of Constantinople and was the ruler of the Roman empire, some of the other countries did not like him and were worried that he would come and try to take them over.

In the country of Persia, there was an emperor named Shapur II who was at war with the country of Rome.
The leader of the Christian church in Persia was named Simeon Barsabae.
Shapur II got angry with him and all the other leaders of the church because they were Christian, and the Roman empire was the head of the Christian church, so he killed Simeon and thousands of other Christians to try and stop Christianity from coming into his country.

La Mojarra Stela 1

We just learned about the Double Headed Serpent.

Another ancient sculpture from Mesoamerica is the La Mojarra Stela 1 made some time before 200 AD, in Veracruz Mexico.

We've learned before that a stele or stela is a tall stone or wooden slab that has carvings and usually writings on it, to honor someone that died, someone winning a battle, or an important set of words that people need to remember.

This stela is a carving of an warrior in a costume, and it has some writing on it about the warrior.
