Maxilla

Let's learn the other parts of the facial skeleton!

We've already learned about the mandible.

Next up is the maxilla, which is your upper jaw and behind your nose.

Venezuela, Suriname, Guyana, French Guiana

We just learned about the countries of Peru and Ecuador.

The last 4 countries that make up the northern part of South America are Venezuela, Surinam, Guyana and French Guiana

Venezuela got it's name from traveler Amerigo Vespucci, who thought the many houses on water reminded him of Venice, Italy.

It is the site of Angel Falls, the highest waterfall in the world.

Suriname was originally a Dutch colony, and is the only country in North and South America where Dutch is the official language.

Guyana is the only South American country where the official language is English.
The original land called Guiana was much larger and included Guyana, Suriname, French Guiana, and parts of Colombia, Venezuela and Brazil.

French Guiana is a territory controlled by France, and it has the Guiana Space Centre there, the place that Europe usually uses to launch rockets into outer space.

Ruth

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

We already learned about Joshua and Judges.

Next up is Ruth.

During the days from the book of Judges, an Israelite woman named Naomi had a husband and two sons.
Both of the sons married women that were from the land of Moab, where they didn't know about God's laws and his people.

Then Naomi's husbands and her two sons both died!
She was alone, and only her one daughter in law Ruth stayed with her.

Naomi and Ruth both returned to Bethlehem, and there Ruth worked very hard to help gather leftover crops, and because of her hard work a man named Boaz noticed her and ended up marrying her!

Ruth was a very important mother, because her great grandson was David who went on to be king of Israel.

Atmosphere

We just learned about how meteoroids become meteors or shooting stars when they get close to a planet.

They burn up because of a planet's atmosphere.
The atmosphere is the air up in our sky!

Just think about how a strong wind feels blowing on your face.
That wind is maybe blowing at 20 miles per hour.

Now imagine that wind blowing at 100,000 miles per hour!
That's how fast some meteors travel when they enter Earth's atmosphere,
and they burn up because they're going so fast they can't handle that kind of wind.

French - Her hands are soft

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

To say Her hands are soft, you would say Ses mains sont douces.

Her - Ses - sounds like say /?/
hands - mains - sounds like mahnz /?/
are - sont - sounds like soh-n /?/
soft - douces - sounds like doose /?/

All together it sounds like say mahnz soh-n doose /?/

Acceleration

Last time we learned how kinematics is the study of measuring how things move.
We learned about distance, time and velocity.

There's another fun thing we can measure, called acceleration.

Imagine you are in a race car at the starting line.
As soon as the race starts you are going to speed up to go as fast as you can, until you cross the finish line.

How fast were you going right before the race started?
Your velocity was zero, (0 mph) because you weren't moving.

And by the time you crossed the finish line maybe you were going super fast,
so your velocity was 100 mph.

When we want to measure how fast you sped up, that's called acceleration.
We usually use the letter a for acceleration.

We're measuring how much velocity (v) changes over time (t).
Velocity is in miles per hour (mph) or meters per second (m/s).
Time is in hours (h) or seconds (s).

So m/s / s = m/s^2, meters per second per second or meters per second squared.

It might sound funny, but that's how we measure how fast we changed from one speed to another.

Kangaroos

We just learned about the Spider Monkey.

Kangaroos are a type of animal known as a marsupial.

Marsupials carry their babies in a pouch. Baby kangaroos are known as joeys.
