Valve


We just learned about the Cam.

Another part of moving things like machines is a Valve.

This is something that opens and closes to let air or water in or out.
We use valves every day, like when we turn on the water to wash hands.

Turning the water on opens the valve, and you can usually open it a little or a lot.
Then turning the water off closes the valve.

Nematocysts


We just learned about the Tentacles of a jellyfish.

Another part of a jellyfish is the Nematocyst.

This is the part of the jellyfish that stings its prey, or even stings a person.

They are almost like traps on the jellyfish's tentacles that just wait until they get touched a tiny bit, and then they shoot out and then squirt toxins into their prey to stun them or kill them.

Ciliary Body


We just learned about the Fibrous Tunic where the Cornea and Sclera are.

Another part of the eyes is the Ciliary Body.

This is made up of two parts: the ciliary muscle, and the ciliary epithelium

The muscle is what squeezes the lens inside the eye to change its shape so you can look at things far away or close up.

The epithelium is what makes the aqueous humour that fills the front of the eye where the pupil is.

Czech Hedgehog


We just learned about the Dragon's Teeth used to stop tanks.

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 and Attila


We just learned about the Saint Patrick who told people in Ireland about Jesus.

Another part of ancient Christianity was the meeting between Leo and Attila .

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.

A person who goes and meets with other leaders of countries is called an "Ambassador" and Pope Leo was thought to be a very good ambassador because he helped save Rome from Attila the Hun.

Toltec Atlantean figures from Tula


We just learned about the Montezuma's Headdress.

Another famous Mesoamerican ancient sculpture is the Toltec Atlantean figures from Tula.

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.

The statues are over 15 feet tall, have butterfly shaped armor, sun shields, feathered helmets, and spears.
They were warriors that were meant to serve the mythical Quetzalcoatl from ancient times in Mexico.
