Ostrich

We just learned about the little bird called the Kiwi.

The biggest bird in the world is the Ostrich.

It can't fly, but it can run faster than any other bird,
and about twice as fast as a human, at 43 miles per hour!

The ostrich egg is the largest egg of any living bird,
about 10 times bigger than a chicken's egg.

Sometimes if an ostrich is frightened, it will put it's head low to the ground,
so that from far away it just looks like a large pile bush instead of a big bird!

Forearm Extensors

Let's keep learning about the muscles in the human body!

Last time we learned about how the Forearm flexors are used to help flex your elbow together.

Even though the forearm muscles are smaller than biceps, there are a few other important muscles there too.

The extensor muscles are the ones you use when you move the back of your hand up toward your forearm,
or when you open up your hand and spread out your fingers.

Luke

Let's keep learning about the four Gospels in the New Testament.

We've already learned about Matthew and Mark, next up is Luke.

The book of Luke has 20 miracles, 16 of which also appear in some of the other 3 gospels.

It also tells of the angel Gabriel bringing the good news to Mary that she was going to have baby Jesus.

History tells us that Luke was a doctor, an artist and a historian.

French - counting to ninety nine

We just learned how to count to 89 in French, let's keep going!

Just like seventy was really sixty-ten and eighty was four-twenties, ninety is also a little different.
The word for ninety is quatre-vingt dix which means four-twenties ten because 20 times 4 is 80, plus 10 is 90!

90 quatre-vingts dix - sounds like cat-uh-ah vah-n dee /?/
91 quatre-vingt onze - sounds like cat-uh-ah vah owns /?/
92 quatre-vingt douze - sounds like cat-uh-ah vah dooz /?/
93 quatre-vingt treize - sounds like cat-uh-ah vah tuh-ay-z /?/
94 quatre-vingt quatorze - sounds like cat-uh-ah vah cay-tow-z /?/
95 quatre-vingt quinze - sounds like cat-uh-ah vah cay-unz /?/

LEDs

We've now learned about diodes, photons and electroluminescence.

Wow!

Now let's learn about something called LEDs.

LED stands for light emitting diode.
Remember that a diode is a special thing you run electricity through.

When you put electricity through an LED, it shoots off photons,
which are tiny little light particles.

And the photons make the diode light up, using electroluminescence,
which means it gives off light when electricity goes through it.

LEDs can be made in just about every color, and unlike a light bulb they won't burn out!
