Rocket Propellant


Let's learn a little more about Rockets!

One thing that all rockets need is something called propellant.

This is the fuel used to push a rocket through the air.
Propellants can be solid like gunpowder, liquid like water, gasoline or liquid oxygen, or they can be a gas, like compressed nitrogen, or just pressurized air.

When the rocket is started, the propellant shoots out of the rocket at a super fast speed, pushing it along.
So this could be just a long skinny water balloon that shoots out it's water, or it could be a fireworks bottle rocket that burns up it's powder and shoots fire out the back.

The propellant is the stuff inside the rocket that makes the rocket go.

Firefly Squid


We just learned about the Cirroteuthis.

Another type of cephalopod is the Firefly Squid also known as watasenia scintillans.
They are usually about 3 inches long, and live in the Pacific Ocean.

This type of squid is bioluminescent.
That means parts of its body light up, kind of like a firefly.

There are tiny little dots all over the squid's body with organs called photophores.
The squid uses these photophores to light up, which makes small fish swim toward them, and they eat them up!

It also uses its body lights to make its top bright and bottom dark so it can hide from other predators.

When it is looking around for another firefly squid it will light up it's whole body as a signal.

Talocalcaneal Ligaments


We just learned about the Talocrural and Ankle Ligaments.

Another group of ligaments are the Subtalar and Talocalcaneal Ligaments.

The talus and calcaneus are two of the seven ankle and foot bones.
The talus is the middle foot bone, and the calcaneus is the heel.

Posterior is for back, anterior is for front, lateral is for outside, medial is for inside, and interossus is for in between.
There five talocalcaneal ligaments: anterior, posterior, lateral, medial and interosseous

Campeche


We just learned about the Mexico state of Nayarit.

Another Mexico state is Campeche.
This state is on the southeast part of Mexico, on the Gulf of Mexico.
It borders Belize and Guatemala to the south.


(from: wikipedia - campeche)

Campeche's coat of arms has pictures of castle towers for the strength of the Campecheans, and sailing ships for the people who were sailing on the ocean.


(from: wikipedia - campeche)

Just like many other states in Mexico, there are ancient pyramids in Campeche.


(from: wikipedia - calakmul)

There are many ancient places in this state where they have found sculptures from over a thousand years ago, like in a small island called Jaina Island.


(from: wikipedia - jaina island)

The Fort of San Miguel in San Francisco de Campeche was built hundreds of years ago to fight against pirates.

Saint Stephen


We just learned about the Ananias of Damascus, one of the Seventy Disciples.

Another of the seventy is Saint Stephen.

After Jesus died on the cross, Stephen was telling people about him and some of the leaders who did not like Jesus were getting angry.
They told some people to tell lies about Stephen, which made other people very angry.
Stephen was put on trial in front of everyone where he told the truth and talked about Jesus.
This made the leaders who did not like Jesus even more angry, and they threw stones at him and killed him.

Because he was killed for believing in Jesus, he is called the first martyr.
A martyr is someone who is killed because of something they believe in.

Terracotta Army


We just learned about the sculpture of The Buddha, flanked by Herakles and Tychee.

Another famous set of sculptures is the Terracotta Army made in China around 200 BC.

When the Emperor of China Qin Shi Huang died, he was put into a tomb with over 8,000 sculptures in it.
These were small sculptures of soldiers, chariots, horses, acrobats and musicians that were buried with him as they believed these soldiers would protect the Emperor in the afterlife.

These thousands of soldiers all had real weapons like spears, swords or arrows.
Many of these weapons have been stolen, but people believe there were over 40,000 weapons in the original sculpture.
The statues were all painted at first, but the paint has all worn off.

The place where these sculptures were buried with the emperor was part of a very large cemetery area that was about 38 square miles.
There were people that visited it long ago and wrote about it saying that there were miniature palaces, towers, 100 rivers of flowing mercury, and paintings on the ceiling of heaven.

Over the thousands of years, many things have been stolen or broken, but there are still thousands of sculptures there to see.

Greek - My drink is cold


We just learned that in Greek to say this chair is small you say Η καρέκλα είναι μικρή (I karékla eínai mikrí).

Let's learn about more things we see every day.

To say My drink is cold, we say Το ποτό μου είναι κρύο (To potó mou eínai krýo).

Some languages say words in a different order, so in Greek you're really saying "The drink mine is cold".

Here's how to say it:

The - To (Το) - sounds like TOH

drink - ποτό (potó) - sounds like poh-TOH

mine - μου (mou) - sounds like MOO

is - είναι (eínai) - sounds like EE-nay

cold - κρύο (krýo) - sounds like KREE-oh


So all together Το ποτό μου είναι κρύο (To potó mou eínai krýo) sounds like TOH poh-TOH MOO EE-nay KREE-oh.

Rockets


We've learned a whole lot about earthquakes.
Everything from tectonic plates, to faults, to aftershocks and the Richter scale!

Let's learn a little about rockets!

Usually when people are talking about rockets, they mean the ones that fly up into the air and go into outer space.
A rocket really just means something that uses fuel in an engine to push itself forward.
So this could be a rocket on the back of a car, a rocket pushing a train, or even a rocket jet backpack!
Even a water balloon filled with air or water that flies around when it is let go is a type of rocket.

Some people think the science of learning about rockets is so hard,
that there is a saying when you want to say something is easy:
"it's not rocket science!"

Cirroteuthis


We just learned about the Grimpoteuthis - Dumbo Octopus.

Another type of cephalopod is Cirroteuthis.

This is an octopus that has webbing in between its arms holding them together.
It almost looks like an octopus wearing a dress!

It can grow to be almost five feet long, and is usually white or purple.
Just like the dumbo octopus, this octopus has fins on its head that it can flap.

They live in the deep sea in cold water, like the Arctic ocean or the south pacific near Antarctica.
Scientists have not been able to find a lot of these, because they live over 6,000 feet deep in the ocean, where there is almost no light.

Talocrural and ankle ligaments


We just learned about the Inferior Tibiofibular Joint connecting the tibia to the fibula.

Another set of ligaments are the Talocrural and ankle ligaments.
These connect the tibia and fibula of the lower leg to the talus, navicular and calcaneus bones of the foot.

There are a bunch of ligaments in this area to make sure your ankle works right, and all the bones are tied together.

They all have big names, but they make sense based on the two bones they are connecting:

tibiotalar (anterior/posterior) - connects the tibia (shin bone) to the talus (middle foot bone)
tibiocalcaneal - connects the tibia to the calcaneus (heel bone)
tibionavicular - connects the tibia to the navicular (foot bone)
talofibular (anterior/posterior) - connects the fibula (inside lower leg bone) to the talus
calcaneofibular - connects the fibula to the calcaneus

Nayarit


We just learned about the Mexico state of Tlaxcala.

Another Mexico state is Nayarit.
It is a smaller state on the west coast of Mexico on the Pacific ocean, and includes the islands of Marías and Marietas.


(from: wikipedia - nayarit)

The coat of arms of Nayarit has a corn plant on the top left. This is for the capital city of Tepic, which comes from the Aztec word for corn, "tepictu".
The top right has a picture of a bow and arrow. The Cora people in this state believed in a mythical being called Nayarit, who their legends say invented the bow and arrow.
The bottom has white mountains, for the Sierra Madre Occidental montains.
The middle has the symbol of Mexico, an eagle eating a snake on a cactus.


(from: wikipedia - nayarit)

One of the islands named Marías has a prison on it, built in 1905 that is supposed to be "escape proof".


(from: wikipedia - islas marías)

On the island of Marietas, there is a hidden beach called "love beach" that is a place people go to visit.


(from: wikipedia - islas marietas national park)

There is a place named Ahuacatlan, that means "place where there is a lot of avocado".
In the Nahuatl language, the word ahua means avocado, and the word tlan means place.

Speleoseismite


We just learned about the seismite.

Another part of earthquake science is Speleoseismite.

In caves there are things called stalagmites that grow from the floor, and stalactites growing from the ceiling.
Sometimes during earthquakes these break, or sometimes cave ceilings collapse.

These broken or tilted rock growths are the speleoseismites, and they can be used to study earthquakes that happened a long time ago.

Tlaxcala


We just learned about the Mexican state of Aguascalientes.

Another state in Mexico is called Tlaxcala.

Not counting the federal district of Mexico City, Tlaxcala is the smallest state in Mexico.

The name Tlaxcala is either from an ancient word that meant crag, a steep cliff face.
Or it comes from the Nahuatl word meaning "place of corn tortillas".


(from: wikipedia - tlaxcala)

The Tlaxcala coat of arms has the letters I K F with crowns on the top.
This is for the kings and queens of Spain, Doña Juana I de Catilla, King Carlos I and King Felipe II.
The yellow castle is for the Castile in Spain, and the flag has an eagle on it because King Carlos was the head of the Holy Roman empire.
The skull and crossbones are for the people who died fighting for their freedom.


(from: wikipedia - tlaxcala)

There is a volcano called Malinche in Tlaxcala.


(from: wikipedia - malinche (volcano))

Thaddeus


We just learned about Matthias, one of the Seventy Disciples.

Another of the seventy was Thaddeus, sometimes called Thaddeus of Edessa, Addai, Aday, Addeus, or Jude the Apostle.

Because there are a lot of stories about some people named Thaddeus or Jude, it can be hard to tell if the stories are about the same person.

Jude the Apostle was one of the twelve that followed Jesus, and also the one who wrote the book of Jude in the Bible.
There are some other stories about Thaddeus going on and spreading the Gospel to other towns.

We just learned about the Kushan Maitreya.

Another work of art in Asia is the Bharhat Stupa, made around 100 BC.

The artwork for this place shows some styles that are a lot like Greek artwork, and also some marks from different types of artists in different areas.
This means the artwork was probably made over several years, with a lot of different people helping.

It was made so long ago and was almost destroyed and buried, so people had to dig it up and try to figure out who made it based on the carvings.

Most of the carvings tell the story of Buddha, a famous wise person from Asia.
