Spider silk - cribellum


We just learned a little about the Spider Silk Webs.

Some spiders have something called a cribellum instead of just normal spinnerets.
When they make silk, it comes out as very tiny string which gets all wrapped around itself and looks almost like it is made of wool.

Because the silk is so tiny and all bunched up, insects get tangled up in it and the spiders can go capture them.

Common Carotid Artery


We've learned how the oxygenated blood goes up the ascending aorta and then turns at the aortic arch.

Right at the arch there are two tubes that go up your neck, called common carotid arteries.
The one on the left is called the left common carotid artery and of course the one on the right is the right common carotid artery.
They go up the side of your neck to bring oxygenated blood to your brain and all the parts of your head like mouth, eyes and nose.

Illinois


We just learned about the US state of Idaho.

Illinois is a state in the midwest area in the US. It borders Lake Michigan on it's north east side, and the Mississippi river on the west side.
It's nicknames are Land of Lincoln because president Abraham Lincoln grew up there, and The "Prairie State" because it was a land covered in prairie grass.

The state motto is: State sovereignty, national union

(from: wikipedia - illinois)

The flag of Illinois has the state seal on it, which shows an eagle holding a shield with USA stars and stripes on it.
In it's beak the eagle is holding a banner that has the state motto in it, state sovereignty, national union.

When Illinois first made their motto they were trying to say that the states should have the rights to do whatever they wanted without the rest of the USA's permission.
So state sovereignty meant the state was the boss, and national union meant they still wanted the USA to be connected as a bunch of states.
That was one of the things that the civil war was fought over. The states on the north union side thought the USA should be the boss over the states, and the south confederates thought the states should be the boss over USA.

Illinois fought in the civil war on the north union side, so later when the flag was redesigned, one of the people who didn't think it was right to have state sovereignty like that had the flag redesigned to have the word sovereignty printed upside down because the south confederacy lost the war.

Arrest of Jesus - Jesus' Prayer


After Jesus had eaten the Last Supper with his disciples, they went out to a place called Gethsemene.

There Jesus went for a walk by himself to pray.
He prayed to God the Father and said "My Father, if it is possible, may this cup be taken from me. Yet not as I will, but as you will."

He wasn't talking about an actual cup, but the job that he had to do that was very difficult.
Jesus knew that very soon he was going to die on the cross for the sins of the whole world, and this was a very hard thing to do.
He asked God for help, and said that he would do whatever God commanded.
When he got done praying he want back to his disciples who had all fallen asleep!
He told them to wake up and pray so that they would be strong.

Whistler's Mother - Whistler


We just learned about the famous painting The Great Wave off Kanagawa by Katsushika Hokusai.

Another famous piece of art is the painting Arrangement in Grey and Black No.1 by painter James McNeill Whistler in 1871.

The painting is better known by it's nickname Whistler's Mother, because it is a painting of Anna McNeill Whistler, who was the painter's mother.

Many people have asked what the painting means or what is the story behind it, but the artist Whistler very strongly believed in something called Art for Art's sake.
This means that he believed his paintings should be good enough for someone to enjoy, just by looking at them.
In French this was called l'art pour l'art which means "the art for the art".

Since it is a famous painting of an artist's mother, this painting has been used many times as a way to get people to remember their mothers and feel good about them.

Dew Point


We've just learned about all types of weather fronts, like a stationary front and what happens when warm air and cold air run into each other.

When the water vapor in warm air is lifted high up into the sky, it gets colder.
The colder temperatures will eventually turn the water vapor back into tiny water droplets if it gets too cold.

The temperature that the water vapor changes into water drops is called the dew point.
If it is colder than the dew point, it turns to water.
If it is hotter than the dew point, it turns to vapor.
