Air Resistance


We just learned about Ballistics.

One part of ballistics is Air Resistance, which is also called drag.

When the rocket is flying through the air, it is pushing the air out of the way.
The shape of the rocket can make a big difference for how fast it can fly through the air.

If you think about it like pushing your hand through the water, if you point your hand it will go in the water fast.
But if you use the open flat part of your hand and smack the water, your hand will be more like a paddle and you'll slowly push the water out of the way.

We don't think about it much for air, but it works the same way for rockets trying to push through the air.
So the front of the rocket has to have a pointed shape for it to fly quickly.

Japanese Flying Squid


We just learned about the Opalescent Inshore Squid.

Another Japanese Flying Squid.

These squids live in the Pacific around Japan and Vietnam, and can grow to around 2 feet long.

They swim along by sucking water in on one side of their siphon, and then spitting it out the other side like a jet.

Sometimes they will swim so fast that they will shoot themselves up out of the water, and have been seen flying for almost 100 feet over the water!

Cementum


We just learned about the Dentin.

Another part of the tooth is Cementum.

This is a hard covering for the tooth just like the enamel that we learned about, but it is covering the part of the tooth going down below the gums, called the root.

Windsor Castle


We just learned about the Hohensalzburg Fortress.

Another famous castle is Windsor Castle, built around 1000 AD in Windsor, Berkshire, England.

Unlike a lot of other castles, this one has been lived in for a very long time by the royal family of England, like the King or Queen.

It covers over 10 acres, and has different areas called "wards" that have apartments or even a church called St. George's Chapel.

The queen of England still lives there on most weekends, and the royal family uses the castle as a place to have parties and do business.

Olympus and Rhodion


We just learned about the Philologus - Bishop of Sinope, one of the seventy disciples.
t Caius - Bishop of Ephesus, one of the seventy disciples.
Another two of the seventy were Olympus and Rhodion.

Rhodion was also known as Herodion of Patras, and he was a relative of Paul and became a leader of the church in the town of Patras.

He had a very rough life and was beaten up by people who didn't like to hear what he said, and eventually he was killed along with his friend Olympas.

Eight Nested Relic Boxes


We just learned about the Seven Sages of the Bamboo Grove.

Another ancient Chinese work of art is the Eight Nested Relic Boxes.

Long ago in China a man called Buddha lived and many people followed him because of all the wise things he had to say.

He was so famous that when he died, they saved one of his finger bones and put it inside of a nicely carved box.
This box was put into another box and another.
There were a total of eight boxes, made of either gold, silver or jade, and wrapped in silk.

These boxes are in a museum now for people to come visit and see the box that people believe has the finger bone of Buddha inside.
