Lymphatic System

We just learned about Presbyopia.

We've learned a whole lot about Eyes, from the Cornea, Pupil, Iris and Retina to the Rods, Cones and Fovea!

Let's move on now and learn about something else, called the Lymphatic System.

This is a part of the body that helps make new blood cells, and also helps fight off diseases.
It's part of both the circulatory system and immune system, and goes through the whole body.

The lymphatic system isn't as well known as other parts of the body like the bones or muscles, but it was discovered over 300 years ago, so scientists have been studying it for a long time to figure out how the body works.

Antarctic Circumpolar Current

We just learned about the Nunatuk rock formations.

Another part of Antarctica is the Antarctic Circumpolar Current, also called the ACC.

In the ocean around Antarctica the water flows around it in a clockwise loop.

This water flow called a current is the largest ocean current in the world, mostly because it flows around and around without hitting any other land.
Most other ocean currents eventually run into other continents.

The looping current goes around Antarctica and the south pole like a circle, which is why it's called "Circumpolar".
With the water going around and around, it helps keep the warmer ocean water from getting to Antarctica.
This helps keep the south pole cold and the glaciers from melting.

Rosary

We just learned about the Franciscans.

Another part of early Christianity is the Rosary.

In 1214 AD, a Spanish priest named Saint Dominic said that he had a dream of Mary the mother of Jesus.
She told him to make a necklace with beads on it, and the beads would be used to help say prayers.

Most rosaries have 59 beads, and a cross. The beads are either "Our Father" beads or "Hail Mary" beads.

Four of the beads hang down from the circle necklace, with the cross.
The circle necklace is grouped in 5 sets of haily mary 10 beads called "decades" or "mysteries" and separated by 1 our father bead.

When praying, a person starts at the cross, then moves up the chain to the circle, then around the circle saying a prayer for each bead.
Many prayers have to be memorized in order to do the whole rosary: The Apostle's Creed, The Lord's Prayer, Glory Be, Hail Holy Queen.

So for a full rosary reading, you would say:
- (From the crucifix) - The Apostle's Creed, The Lord's Prayer, 3 x Hail Mary, Glory Be
- (Mystery 1) - The Lord's Prayer, 10 x Hail Mary, Glory Be
- (Mystery 2) - The Lord's Prayer, 10 x Hail Mary, Glory Be
- (Mystery 3) - The Lord's Prayer, 10 x Hail Mary, Glory Be
- (Mystery 4) - The Lord's Prayer, 10 x Hail Mary, Glory Be
- (Mystery 5) - The Lord's Prayer, 10 x Hail Mary, Glory Be
- Hail Holy Queen

Mount Rushmore

We just learned about the Vietnam Veterans Memorial - Maya Lin.

Another famous American sculpture is Mount Rushmore, made by Gutzon Borglum in 1941 in South Dakota.

This sculpture was made of 4 presidents: George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln.
Each of the heads is about 60 feet tall, and mountain is about 5,700 feet high.

The first idea for a sculpture on this mountain was to have some American West heroes like Lewis and Clark, Scagawea, and some famous Lakota Native Americans, but sculptor Borglum chose the presidents as he thought they would be a more popular tourist attraction.

Tender

We just learned about the Fire-Tube Boiler.

Let's go step by step and learn all the parts of a working steam locomotive!

One part of the locomotive is the Tender, or coal car.

This is a big box that is pulled behind the engine that is full of the fuel that the locomotive needs to run.
It can be full of wood, coal or oil, and it also is full of water that is used for the steam.

Usually the water was on the bottom of the tender, in a place called the water compartment.
The coal or other fuel was on top in a place called the coal bunker.

The engines used a lot of water, which is why railroads came up with places to refill with water using big cranes when they stopped at train stations.
