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.

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.

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

Spider Monkeys are called that because they have very long arms and legs.

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!
