Threading

We just learned about the Skiving Machine.

Another type of metal working is called Threading.

If you've ever seen a nut that spins onto a bolt, you've seen something made by a tap and die.
The nut has to be cut exactly right to fit onto the screw, or else it won't screw on.

The tap is the tool that cuts the hole into the nut or other hole where the screw will go.
The die is the tool that cuts the lines onto the screw so it fits into the nut.

There are hand taps and dies that you can use with just your hands if you are strong enough, or there are machines that use strong motors to cut into the metal.

Common Suriname Toad

We just learned about the Red Eyed Tree Frog.

Another type of frog is the Common Suriname Toad, also called the star fingered toad.
Just like some of the other toads we've learned about, this is not a "True Toad", it is a frog with a toad name.

This is a flat grey toad that lives mostly in the water.
One really interesting thing about this toad is that they don't lay eggs in the water like a lot of frogs.
The mother carries the eggs around inside the skin on her back, in little pockets like a honeycomb.
The eggs hatch and the tadpoles stay inside the mother's back until they grow into tiny little toads, and climb out of their mother's back.

Hypodermis

We just learned about the Dermis.

Another part of the skin is the Hypodermis, also called the Subcutaneous tissue.
This is the skin below the Dermis, which is below the Epidermis.

The body mostly has fat cells in the hypodermis, but it also has white blood cells and blood vessels.
There is also something called deep fascia or connective tissue that connects your muscles to your skin.

Sierra Madre Oriental

We just learned about the Rocky Mountains.

Another group of mountains in the Laramide Belt of the North American Cordillera is the Sierra Madre Oriental.

These mountains go from the south part of Texas, and down the east coast of Mexico.
They are on the other side of Mexico, where the Sierra Madre Occidental is on the west side.
These mountains are drier than the rainforest areas south of the mountain ranges.

Josiah

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

Another person from the Bible was Josiah.

Josiah was one of the many Kings of God's people of Judah.
When he was king, the people of Judah had not been very good about following God's laws for a long time.
Many people had even forgotten what the laws were, because the books where the laws were written had been lost.
When Josiah told people to start cleaning up God's temple, the high priest named Hilkiah found the Book of Law, and brought it to Josiah.

Josiah heard what the book said and was very upset when he found out that they were breaking many of God's laws and not living the way they were supposed to be.
He ordered that all the people had to stop doing all the bad things they were doing, like worshipping false idols, and go back to worshipping God the way they were supposed to.

Scaliger Tombs

We just learned about the Pulpit of Sant' Andrea.

Another famous Gothic Art sculpture is the Scaliger Tombs.

The Scaliger family ruled in Verona Italy for over 100 years, and these tombs were made to honor the rulers when they were buried in them.
The tombs are covered in sculptures of the family, then surrounded by sculpted columns, walls and spires with statues, and on top is a large statue of the ruler riding a horse.

ASL - Their car is tall

We just learned in ASL how to say My Food is Hot

Let's learn how to say Their car is tall.
Remember to say they, you point your finger off to the side and draw a small circle in the air.
Their is just like that, but instead of pointing your finger you wave your open hand in that area.

To say car, hold your hands in front of you in fists side by side like you are holding a steering wheel, and move them like you are turning the steering wheel left and right.

To say tall, put your right hand up by your forehead almost like a salute, and then move your hand forward and up, like you are showing how tall someone else is.

Here are some helpful videos to show how these signs are done.
