Forensic Firearm Examination


We just learned about Ballistic Fingerprints.

Another type of science is Forensic Firearm Examination.

When guns are made, they are each given a special different code number called a "serial number".
No two guns have the same number, and when someone buys a gun they keep track of who owns which gun with which serial number.

This is done so that if a gun is used for a crime, the police can look at the serial number on the gun and figure out who owns the gun.

The serial number is printed right into the metal of the gun.
Sometimes people try to scrape off the metal where the serial number is, but police can use special electromagnets and chemicals to tell what the serial number was even if it has been scraped off.

Some guns these days are also being made to mark the serial number of the gun on the bullet when it is fired.
That way each bullet can be tracked down to who fired it if a crime is committed.

Irukandji Jellyfish


We just learned about the Immortal Jellyfish.

Another type of jellyfish is the Irukandji Jellyfish.

This is the smallest type of jelly, and also one of the most venomous ones in the world!

They can be as small as 0.2 inches, and as big as a little less than 1 inch.
Their tentacles can be as short as less than one inch, or as long as 3 feet.

If this type of jelly stings a person, after about 30 minutes they can have headaches, muscle pains, throwing up, or even a heart attack.
It can take a few hours to get better, or sometimes a day or even a few weeks!

Such a small jelly that pack such a dangerous sting can be scary to watch out for in the water.
These jellies mostly only live around Australia on the north side.

Hard Palate


We just learned about the Sublingual Caruncle.

Another part of the mouth is the Hard Palate.

This is the roof of your mouth, right over your tongue.
You can push up on it with your tongue, and it is hard because there is bone right there underneath the skin.

Edict of Milan


We just learned about the Edict of Serdica.

Another part of early Christian history is the Edict of Milan, written in 313 AD.

When the Emperor Galerius said that it was ok to be a Christian, there were still a lot of old churches and things that had been taken from Christians.

The Emperors Constantine and Licinius decided that everyone should be free to worship whoever they want, and they ordered that all of the things that were taken from the Christians had to be returned.

So this mean that churches or anything like crosses, sculptures or anything that was seen as Christian had to be given back to the Christians so they could have freedom to worship.

To say her hands are soft you would say Hennes hender er myke.
Her - Hennes - sounds like heh-neh-ss
hands - hender - sounds like hen-deh-r
are - er - sounds like ah-r
soft - myke - sounds like mee-kay
