Snake - Molting

We just learned about Snake Scales.

Another part of snake biology is when snakes shed their skin, called molting, sloughing or ecdysis.

Snake skin cane get dirty, worn out, and even covered with bugs like mites or ticks.
So to keep their skin fresh they will peel off the outside layer and have fresh skin and scales underneath.

Usually when a snake is getting ready to shed its skin, it goes and hides somewhere safe.
Then the new layer of skin underneath the old layer gets gooey and slippery.
The snake finds a rough or sharp thing to catch the dry outer skin on, then they keep slithering along.
Just like pulling a sock off, the snake pulls its old skin off and then goes on its way with a nice clean fresh skin.

Younger snakes can shed their skin 4 times a year, and an older snake may only shed their skin 1 or 2 times a year.

Autonomic nervous system

We just learned about Brachial Plexus

Remember we learned that the Nervous System is split up into two parts, the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).
And that part of the Peripheral Nervous System is the Somatic Nervous System.

Another part of the Peripheral Nervous System is the Autonomic Nervous System.

This part of your nervous system controls your internal organs, like your heart, stomach or liver.

Coast Mountains

We just learned about the Yukon Ranges in the Pacific Coast Belt of the North American Cordillera.

Another mountain range in the Pacific Coast Belt is the Coast Mountains.
On the west side of these ranges is a temperate rainforest, which then leads to ice fields and glaciers in the middle, and on the east side is plateaus and forests.

This mountain range has the largest bunch of ice fields in the world.

Jacob

We just learned about the Bible person Esau.

Another person from the bible was Jacob.

Jacob was Esau's younger twin brother.
The Bible says that when Jacob was born, he was holding on to Esau's leg.

One time when Esau came back starving from hunting, he was so hungry he gave Jacob his birth right in trade for a bowl of stew.

Jacob was always his mother Rebekah's favorite, because he helped out around the camp while Esau was out hunting.
One day when his father Isaac was going to give his blessing to Esau, Jacob went in and tricked his father into giving him the blessing instead.
Isaac was blind, but Esau was very hairy, so Jacob put on some fur to pretend to be him, and Isaac gave him the blessing.

Esau was so mad at Jacob that he wanted to kill him, so Jacob ran away from home, and didn't come back to see Esau again for a long time.

Later on Jacob's name gets changed to Israel

Shrine of the Three Kings

We just learned about the Brunswick Lion.

Another Romanesque art sculpture is the Shrine of the Three Kings.

These are three golden sarcophagi, which are boxes for holding people's bodies after they have died.

The three people whose bodies are in the boxes are said to be Three Wise Men or Three Kings from the Bible that brought gifts to Jesus.

They are made of wood, then covered with gold and silver, and over 1,000 jewels and beads, and even some cameos.

The golden outside has 74 sculpted pictures of apostles, prophets, and stories from the Bible.

Another tool for metal working is the Blast Furnace.

A blast furnace is like a giant bloomery, so it's a big chimney with ore going in the top, fire and air getting blown into the bottom, and it burns for a long time.
