Mandible


We've now learned about all the parts of the neurocranium area of the cranium like the Temporal Bone.

Remember the other part of the cranium was the facial skeleton, also called the splanchocranium or viscerocranium.

There are several parts to that bone as well, such as the mandible.

The mandible is also known as your jawbone. It's the part of your skeleton that holds on to your teeth.

Peru and Ecuador


We just learned about the country of Chile and Bolivia.

Two more countries to learn about in South America: Peru and Ecuador.

Peru is on the Western coast of South America.
The largest river in the world, the Amazon River runs through the middle of this country.

Ecuador is just North of Peru.
It has some old ruins from when the Incas lived there before the Spanish took over.

Also interesting about Ecuador is that they use the same type of money as the United States.
Most other countries have their own currency like pesos, reals or euros,
but Ecuador uses the US dollar as their money.

Judges


Let's keep learning about the other Books of History in the Old Testament.

We already learned about Joshua.

Next up is Judges.

After Joshua dies at the beginnng of the book of Judges, the people of Israel start to disobey God.
So God sends them many different rulers over many years, to serve as Judges for his people.

Some of them are very famous, like:

Gideon - A great warrior for God who led only a few hundred men to battle and defeated thousands.

Samson - A warrior for God that was so strong he couldn't be defeated unless his hair was cut.
He once killed a lion with his bare hands!

Meteorite


We now know that an asteroid is a big rock flying in space,
a meteoroid is a small chunk broken off of an asteroid
and a meteor is a chunk of that meteoroid that burns up in the sky when falling to a planet.

So what's a meteorite then?

If a meteor enters a planet's sky and doesn't burn up all the way,
sometimes it actually hits the planet.

When it actually hits the planet, it's called a meteorite!
Most meteorites are really small like a baseball and don't cause any damage, others are bigger than a car!

French - Our table is short


We've now learned that This house is big is Cette maison est grande
The chair is small is La chaise est petit,
My drink is cold is Ma boisson est froide,
Your food is hot is Votre nourriture est chaud
and Their car is tall is Leur voiture est haut
.
To say Our table is short, you would say Notre table est courte.

Our - Notre - sounds like nuh-tuh-ah /?/
table - table - sounds like tah-bluh /?/
is - est - sounds like ay /?/
short - courte - sounds like coh-ut /?/

All together it sounds like nuh-tu-ah tah-bluh ay coh-ut /?/

Kinematics


We've learned now about measuring distance, time and velocity.

A word for the way these things work together is called kinematics,
which really just means a way to understand moving things.

Using kinematics, we can use the things we can measure in a special way,
we can use two of them to figure out the third one!

So if you drive in a car, and you know how fast you went (velocity v)
and how long it took you to get somewhere (time t)
you can figure out how far you went! (distance d)

Let's say we went 10 miles per hour (v = 10mph)
and we went for 2 hours (t = 2h)

We can figure out our distance (d) by multiplying v times t.
If you know some algebra, it looks like this:
d = v * t
d = 10mph * 2h
d = 20 miles

We can do the same thing with time, but we divide our distance by our velocity:
t = d / v

And we can get velocity if we have distance and time.
d = v * t

Fun!

Temporal bone


We learned before that the frontal bone, parietal bones, occipital bone, ethmoid bone and sphenoid bone are part of the neurocranium.

The last part of the neurocranium is the temporal bone, located on the side of your head at your temple.
