Freshwater Jellyfish


We just learned about the Creeping Comb Jelly.

Another type of jellyfish is the Freshwater Jellyfish, also called the Craspedcusta Sowerbii.

Just like the name says, this jellyfish lives in freshwater, not in saltwater like the oceans.

It comes from China, but it has been found pretty much everywhere in the world, from North America to Australia.

It grows to about one inch wide, and has tiny little tentacles that have stingers to catch its prey, but the stingers aren't strong enough for a human to even feel the sting.

Iris


We just learned about the Pupil black circle in the eye.

Another part of the eye is the Iris.

The iris is the part of the eye with color.
Most eyes are either brown or blue, but they can be other colors like green, hazel, grey or red.

Remember that the pupil is just a hole that lets light in to the eye to see.
The iris has the muscles that make the pupil bigger or smaller.

Drawbridge


We just learned about the Castle Keep.

Another part of a castle is a Drawbridge.

This is a type of bridge that goes across a moat, that can be pulled up to keep people from getting into the castle.

Drawbridges are still used today for bridges that go across rivers or lakes.

There are a few different types of drawbridges, like a bascule bridge that has two ends that lift up in the middle, a vertical lift bridge that has one piece that goes up and down together, or a swing bridge that spins in the middle.

Codex Vaticanus


We just learned that Christology is the study of what Jesus was really like.

Another part of early Christian history is the Codex Vaticanus.

This is the oldest copy of the Bible still existing in the world, written some time around 325 AD, over 1,500 years ago!

It is written in Greek, and has copies of the Old Testament and New Testament in it.

The Codex was found some time around 1400 AD, and has been in the library in Vatican City since then, for over 500 years.

People have used this codex to make sure that the Bibles that people have today teach the history as it was written down over a thousand years ago.

Another African sculpture is the Musawwarat es-Sufra temple in Sudan, built some time before the year 300 BC.

This temple has a large sculpture of an elephant, and a room with some very tall columns.
It also has a relief sculpture of some of the ancient gods from the people who lived back then.

Shaft


We just learned about the Pulley.

Another part of a machine is a Shaft.

A shaft is a long pipe, rod or pole that is on the inside of some kind of bigger spinning wheel.
This can be part of a gear, sprocket or pulley.

When the gear spins around, it turns the pipe.

In some machines, the pipe is used to move something else farther away from the gear.
Like in a windmill, the big wheel outside that is moving has a long shaft attached to it.
The shaft goes into the building where it is hooked up to other gears to turn them and do something useful like grid up corn into flour.

When the windmill turns, the shaft spins, and the gears inside spin and do the work.

A car also has a shaft. When the car burns up gas it makes a shaft spin which then connects to other shafts that turn the wheels.
