Lobed Comb Jellyfish


We just learned about the small Barrel Jellyfish.

Another jellyfish is the Lobed Comb Jellyfish, also called the common northern comb jelly, or the bolinopsis infundibulum.

It grows to about 6 inches long, and lives mostly in the northern Atlantic Ocean.

This type of jelly is see through or sometimes milky white.
It has two small tentacles, and it's mouth is at one end of its body.

They have little tiny hairs along their body that they use to swim around.
On their body they have parts that light up using bioluminescence.
This means some chemicals in their body mix together to change colors and glow in the dark.

Palatine Raphe


We just learned about the bump of skin behind your front teeth called the Incisive Papilla.

Another part of the mouth is the Palatine Raphe.

This is the bump on the roof of the mouth in the middle that goes from front to back.
Some people have a big bump that sticks out, but for others it is just a little bump.

Machicolation


We just learned about the Battlements on the top of the castle where people defend from attackers.

Another part of a castle's defense is the Machicolation.

This is a place where the top of the wall sticks out a little and there is a hole where people can drop things down on attackers.
It isn't a low spot in the wall like a crenel, the wall is still high there like a merlon, but it sticks out.
In the old days people would use that spot to drop big rocks or pour hot water or oil on people trying to break into the castle.

One famous machicolation we already learned about is at Blarney Castle in Ireland.
The stone on the bottom of the machicolation is called the Blarney Stone, and kissing it is for good luck!

Church of the Nativity


We just learned about Saint Helena, the mother of Constantine.

Another part of early Christianity is the Church of the Nativity.

After the emperor Constantine became a Christian, he sent his mother Helena out on a trip called a pilgrimage to go and find some of the holy places from the history of the Bible.

She went to Bethlehem and found the place where Jesus was born.
After she found it, she set up a church there, and it has been there for over 1,600 years, since 327 AD.

In the church there is a spot on the ground where people believe Mary was when Jesus was born.
There is a 14 pointed star on the ground, with a circle hole in the middle.
The points on the star are for the history of Jesus' family from Abraham to David, David to when the Hebrews were captured in Babylon, and then from that time to Jesus.
Where the hole is in the middle is a stone that you can touch, that people believe is the actual stone from when Jesus was born.

Trà Kiệu Pedestal


We just learned about the ancient temple Borobudur in Indonesia.

Another famous sculpture is the Trà Kiệu Pedestal, built around 250 BC in Southeast Asia.

Long ago there was a kingdom known as the Champa in the countries of Malaysia and Thailand.
The kingdom and most of the temples were destroyed by other kingdoms, but there was a big temple that had pedestals to hold it up, and one of those was saved.

The Trà Kiệu Pedestal has a bunch of people dancing and playing music on it.
It shows some of the history from that time that is now lost because other artwork was destroyed.

Forensic Botany


We just learned about the Species Test to test blood to see what kind of animal it belongs to.

Another type of forensic science is Forensic Botany.

This is the study of the plants around a place where a crime was committed.
If the police look at a person's shoes or clothes, sometimes they can find tiny pieces of plants that are on them.
It could be just a seed, or a piece of a leaf, or even a tiny bit of pollen from a flower.

If the forensic scientists find evidence of a type of plant, they can figure out what season a crime happened, like fall winter spring summer.
They can also sometimes figure out the place where it happened, like if a type of flower or plant only grows in one area.
Scientists can also look at the plants and figure out how long ago it was that someone was near those plants, because the plants get brown and decay.

Sometimes the pollen, seeds or bits of plants on our clothes are so small that a criminal wouldn't see it and think they got away with a crime, but the forensic scientists look closely and figure it out!
