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.

Chugach Mountains

We just learned about the Kenai Mountains.

Another mountain range in the Pacific Coast Belt in Alaska is the Chugach Mountains.

These mountains are right by the Gulf of Alaska, and because of that they get more snowfall than anywhere else in the world, usually getting over 600 inches (50 feet!) of snow per year.

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.
