Skin

Let's keep learning about the Integumentary System.

The largest part of this system is the skin.

It is the largest organ in the human body, and it makes up about 15 percent of a person's body weight.
That means if a person weighs 100 pounds, their skin weighs 15 pounds!

Human skin has a few layers that help protect the inside of the body from things getting in, and it can heal when it is cut.

Laramide Belt

We just learned about the Interior System of Canada, part of the Nevadan Belt.

Another mountain belt is the Laramide Belt.
We've learned about the Pacific Coast Belt which is on the west coast of North America, and the Nevadan Belt which is east of that.
If we look further east of the Nevadan Belt, the mountains there are called the Laramide Belt, going from Alaska, through Canada, the lower US states and Mexico.

The belt is named after the Laramie Mountains in Wyoming, which were named after an explorer named Jacques La Ramee who disappeared in those mountains in 1820.

Solomon

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

Another person from the Bible is Solomon.

Solomon was the son of David, and Solomon became king.
When Solomon was young, God talked to him and asked him what he wanted.
He asked God to give him wisdom to rule over God's people.
This made God very happy, and he gave him riches and honor to go with his wisdom.

Solomon wrote many wise sayings that are in the Bible called Proverbs and Ecclesiastes, and a poem that he wrote for his wife in the book Song of Solomon.

ASL - The chair is small

We just learned in ASL how to say This house is big

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

To say the chair is small in ASL you first start with the sign for chair.

The sign for chair is with two hands, using your index and middle finger together, with your hands in front of you and your palms facing down, you put your right fingers over your left fingers.

To sign small, first start with two hands in fists in front of you.
Move your fists toward each other one time.

Milling

We just learned how a Metal Lathe is a piece of metal being spun around while a sharp tool cuts it.

Another type of tool for cutting metal is a Mill.

A mill is a machine that has a tool that spins around very fast, while the piece of metal you want to cut is being held still.
So in a way it's the opposite of a lathe, where the metal is spinning and the tool is held still.

Mountain Chicken Frog

We just learned about the Purple Frog.

Another type of frog is the Mountain Chicken Frog.

This frog is called the mountain chicken because it lives in the mountains and is so large it was hunted a lot for food.
Some people think it tastes like chicken, or it is big enough to eat like a chicken.

It is one of the largest frog in the world and can grow to be 8 inches long.
This frog eats a lot, and will eat anything from crickets and millipedes to snakes, bats and even other smaller frogs!
Because it was hunted for food a lot, there are not a lot of these frogs left, so it is now illegal to hunt them.
