Mandible


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

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


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!

and Their car is tall is Leur voiture est haut
.
To say Our table is short, you would say Notre table est courte.

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.

Spider Monkey


Is a spider monkey a cross between a spider and a monkey?

Nope! It's just a monkey with really long arms and legs,
so when it climbs through the trees it sort of looks like a big black spider.

Chile and Bolivia


Two more countries to learn about in South America: Chile and Bolivia.

Chile is a very long thin country along the West coast of South America.
It borders the Andes mountains, and at the South of the continent,
is a tip of land called Cape Horn that sailors used to have to sail around
until the Panama Canal was constructed in Central America.

Chile
(from: wikipedia - chile)

Bolivia is an inland country that also shares part of the Andes mountain range.
It is also home to Spider Monkeys!.

Joshua


We've just finished up learning about the five books that make up the Old Testament books of law

Now let's learn about the next part of the Old Testament, the books of history.

There are 12 books of history: Joshua, Judges, Ruth, 1 Samuel, 2 Samuel, 1 Kings, 2 Kings, 1 Chronicle, 2 Chronicles, Ezra, Nehemiah, Esther.

Let's start with the book of Joshua.

Remember that at the end of Deuteronomy Moses dies and Joshua becomes the leader of the Israelites.

In this book, Joshua leads the Israelites into God's promised land of Canaan,
and conquers all the cities.

The first city conquered is Jericho, and the Israelites conquer it using God's power
by marching around the city 7 times and then blowing their trumpets
and yelling at the wall to make it come crashing down!

Meteoroid


A meteoroid is a smaller piece of a comet or asteroid that has broken off and is floating into space.

When a meteoroid gets close to a planet, it will burn up in the sky.
The burning up is very bright, and it's what we call a shooting star or meteor.

is - est - sounds like ay /?/
tall - haut - sounds like ah-oh /?/

All together it sounds like leh-uh voh-ee-choo-ah ay ah-oh /?/

Velocity


We've learned now about measuring distance and time.

Another thing we can measure is called velocity.

Velocity means speed, or how fast you are going.
It is measured by looking at how much time it takes you to go a distance.
So if you run for 20 meters and it takes you 10 seconds,
then you would say that your velocity was 20 meters per 10 seconds.

If you know your division, you can do 20 / 10 = 2
and then say your velocity was 2 meters per 1 second.

Sometimes we use just one letter for time and distance,
m = meters
s = seconds

So you could write 2 meters per 1 second as 2 m/s

You may also have seen the letters mph before,
that means you are measuring velocity in miles per hour,
and saying how many miles you can go in one hour at the speed you are going.

Uruguay and Paraguay


Two other countries in South America are Uruguay and Paraguay.

Why do their names sound so much alike?
It's because the guay part of their name means river,
and the countries were both named for their rivers.

Paraguay:
paraguay
(from: wikipedia - paraguay)


Uruguay:
uruguay
(from: wikipedia - uruguay)

Uruguay means river of the painted birds
and Paraguay means river that flows to the sea.

We already learned about Genesis, Exodus, Leviticus and Numbers.

The last of the five books of law is Deuteronomy.

The word Deuteronomy means second law.
Just like Leviticus there are many laws listed in this book.

At the end of Deuteronomy Moses dies and Joshua becomes the leader of the Israelites.

Time


Last time we learned about measuring distance.

Another thing we can measure is called time.

We can look at a clock to see what time it is,
and we can also use the clock to count how much time has passed.

So if you get in the car and drive to Gramma's house,
if it takes 30 minutes then that is the time measured.

Time is usually measured in seconds, and there are 60 seconds in each minute.
So if you know your math, you can take 30 times 60 = 18,000 seconds.

Red Panda


The red panda just might be the cutest animal in the world,
but would it make a good pet?

red panda
(from: wikipedia - red panda)

It's only a bit larger than most cats, and smaller than most dogs,
so who knows why this adorable fuzzy crawler hasn't made its way into any homes yet.

Numbers


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

We already learned about Genesis, Exodus and Leviticus.

Next up is Numbers.

The book Numbers is mostly about counting the people of the lord,
and God's people wandering in the desert and complaining too much.

Because they complained too much, God said that not all of them could enter the promised land,
and that Joshua instead of Moses would lead them into the promised land.

Let's talk about measuring things!

First we can learn about distance.

That means how far it is from one place to the next.
So if you drive in your car for 10 miles, then the distance is 10 miles.

(from: wikipedia - taxicab geometry)

You can also measure distances in meters.
A meter is a little bigger than three feet long.

Turtle scutes


When you look at a turtle's shell and see the lines marking out different shapes on it's back or belly, those areas are called scutes
turtle scutes
(from: wikipedia - turtle shell)

The scutes are like scales on a snake, and each scute has a name for where it is on the shell, like cervical, vertebral or marginal.

The scutes are made of keratin, the same as a rhino horns, whale baleen plates and our fingernails and hair!
