Snake - Internal Organs


We just learned about the Snakes - forked tongue.

The parts inside a snake body called the internal orgas all work a lot like a human's, but in a snake they are spread out along it's body.
Because snakes eat big meals and their body stretches out, their organs have to be able to move around or get squished when they are trying to eat something really big.

ASL - Do you speak ASL?


To ask if someone speaks ASL, you might first want to find out if they are deaf or if they are hearing.

The sign for "deaf" is to use your right hand, with your index finger pointing up, touch it to your temple, and then just below your mouth.

The sign for "hearing" is with your right hand, and your index finger pointing to the left, move it in front of your mouth almost like you are brushing your teeth.

The sign for "sign" is with two hands, using your fingers pointing left and right at each other, spin them around each other like a wheel going backwards.

Remember the sign for "you" is just pointing your finger at someone, and the sign for "I" or "me" is pointing at your chest.

ASL is very different than other languages because you would simply say "you deaf", "you hearing" or "you sign".
It's very important to use your face and body to also show what you are saying.
If you are asking a question, make a face like you are asking a question, or lean forward toward the person.
Also many people who are deaf are very good at reading lips, so you can still move your lips or even speak out loud if you are speaking to a deaf person.


To answer "yes" in ASL, you make a fist with your hand, and move it up and down, almost like a puppet's head nodding.

To answer "no" you put your first and second fingers with your thumb, almost like a puppet's mouth, and open and close them twice.

Here is a helpful video showing these signs:

Sponge Iron


We just learned about the Bloomery used to make metal from iron ore.

After the iron ore is put through the bloomery, it creates something called a bloom or sponge iron.

This usually has a bunch of holes in it, and needs to be hammered and put back in the bloomery before it can be used.

Snakes - Forked Tongue


Let's learn more about Snake Biology.

Snakes have a forked tongue.

When they stick their wet tongue out, it gets covered with smelly stuff from the air and the ground.
They bring their tongue back in their mouth, and a part of their body called the Jacobson's organ, the vomeronasal organ or just VNO tells the snake what smells are on the tongue.

Because their tongue is forked, they can tell which smells were from the left, and which were from the right.

So in a way, they smell with their tongue, but their tongue really just gets covered in smells and brings those smells back to a sort of inside nose in their head.

Isaac


We just learned about the person from the Bible named Sarah.

Another person from the Bible is Isaac.

Isaac was the only son of Abraham and Sarah.

When Isaac was young, God told Abraham to take him up to a mountain and offer him as a sacrifice.
This was very scary for Abraham because he loved Isaac, but he feared God so much that he did what God told him to do.
He took Isaac up to the mountain, but when God saw how much Abraham feared him and would follow his orders, he had Abraham sacrifice a sheep instead.
Because he was so faithful to God, he promised that he would bless all of Abraham and Isaac's children and grandchildren.

The Bible tells of Isaac's life in Genesis chapters 21 - 35.

ASL - Please, You're Welcome

Remember that to say thank you in ASL, you move your hand away from your chin, toward the other person..

To say please in ASL you make the "5" handshape with your hand, then put it flat on your chest, and make a circle, like you are rubbing your chest.

There are a few different ways to say you're welcome.
The word welcome in ASL really means more like welcome to my home, so you don't want to sign that.
The easiest way is just to do the ASL sign for thank you again.
You can also do the sign for fine which is the "5" handshape, with your fingers pointed up, touch your thumb to your chest two times.
Another way is to do the sign for nothing, to say "it's nothing". For this sign, you put both your hands in the ASL "O" handshape, and shake them in front of you.

Here are what the 5 and O handshapes look like:

Bloomery


We just learned about the Iron Ore that is used to get iron for blacksmithing.

One way to get the iron out of that iron ore is using something called a Bloomery.

A bloomery is like a chimney, where a fire is made at the bottom with charcoal, iron ore is poured into the top, and there are are holes on the bottom that help bring in air for the fire to keep burning.

Snake Biology


We just learned about 39 different types of snakes!.

Let's learn a little bit about how a snake's body works.

Snakes have many of the same body parts like we do, like hearts, lungs, vertebrae, but they are smaller, stretched out, or in different places.

One thing we have that snakes don't have is ears outside their body!
Long ago people used to do something called snake charming, where they would play a flute and a snake would rise up out of a basket like it was in a trance.
The trick really was the way the flute was being moved, because the snake couldn't really hear the flute!

Sarah


We just learned about Abraham from the Bible.

Abraham's wife in the Bible was named Sarah.

Just like Abraham started out as Abram, Sarah's name started out as Sarai.
When Sarai traveled with Abram to Egypt, Abram was worried that bad people might hurt him so they could take Sarai from him, so he lied and said she was his sister.
The Pharoah took Sarai as his wife, but then bad things like plagues came to his kingdom.
He found out that Abram had lied, so he made him leave Egypt.

Sarai was sad because she could not have any children for a long time.
When she was 90 years old God told her she would have a child!
She laughed because she thought she was too old, but she did have a son the following year.
God was happy with Sarai and changed her name to Sarah.

The Bible tells the story of Sarah in Genesis Chapters 11 - 23.

Stenkvista Runestone


We just learned about the Gero Cross.

Another ancient sculpture from the same time, was the Stenkvista Runestone.

This was made in Sweden, where was a large stone carved near a grave to honor someone who had passed.
In the northern countries of Europe, they believed in the mythical Norse gods like Thor.

On the rune stone, you can see what looks like an upside down capital letter T.
That is Thor's hammer Mjölnir.

The words carved in the stone are in old letters called runes, and the words mean:
Helgi and Freygeirr and Þorgautr raised the rune-decorated landmark in memory of Þjóðmundr, their father.

ASL - Very good thanks, and you?


We just learned how to say How are you? in ASL.

To respond, you might say "Very good thanks, and you?".

Remember we already learned the sign for good, moving the hand away from the chin.
The sign for good and thank you are almost exactly the same.
Usually the only difference might be that for "thank you" instead of moving your hand down, you move your hand out toward the other person and then down.
Or you can have your left base hand out for good, but not for thank you.

Then to say "and you", you would just do the same sign for "How are you?" that we learned.

Here is a helpful video showing these signs:

Anaconda


We just learned about the Timor Python.

Another type of snake is the anaconda.

This is the heaviest snake in the world, usually growing to around 150 pounds.
The largest anaconda ever found was over 200 pounds!

Their eyes and nose are on the top of their head, so when they are hiding in the water they only need a little bit of their body in the air to breathe.


(from: wikipedia - anaconda)


These snakes are not venomous, they are constrictors so they kill their prey by squeezing them.
They are so large that they can eat tapirs, deer, capybaras, caimans, jaguars, and even other anacondas.

This crucifix is over six feet tall, and is made out of oak wood, painted, and gilded with some gems.
The oval and sun rays behind the crucifix were added about 700 years later.

It is different from other sculptures of the time, because other crucifixes showed Christ alive with his eyes open looking out.
This crucifix shows him after he died on the cross, looking sad.

ASL - How are you?


We just learned how to say Hello, Goodbye and Good Morning in ASL.

If you want to say How are you? in ASL, you start with how.

The hand shape you start with is like the "Bent B".


ASL bent b
(from: wiktionary - appendix:sign language handshapes)

It's like the Bent B, but not exactly the same.
Keep your thumb up, bend your hand, point your fingers down, and your palm is facing down.
You do this with both hands, have them meet in front of you with the backs of your fingers facing each other.

Then rotate your hand at the wrist, bringing your fingers up toward the inside of your body until they are pointed up.

After that make the hand shape for "1" with your index finger, and point at the person you're talking to.

A lot of ASL also uses your face and your body, so it helps if you lean forward to show that you are interested in how someone is.

Here is a helpful video showing this sign, and also a way to say "What's up?" that you might say to your close friends:

These snakes are constrictors, and they are not venomous.
They can grow to be 7 feet long, but they are thinner than most pythons.
They live in trees, and mostly hunt at night in the trees.

Even though they are called the Timor Python, none of these snakes live on the island of Timor in Indonesia.
When they lay their eggs, they will stay curled up around them until the eggs hatch.
Sometimes to warm up their bodies they can twitch and contract and that helps keep the eggs warm.
