John


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

We've already learneda bout Matthew, Mark and Luke.
The last of the four gospels is John.

John was the cousin of Jesus, and one of the Apostles.

One of the most famous things from the Bible is from the book of John, chapter 3, verse 16:
For God so loved the world, that he gave his one and only Son, that whoever believes in him should not perish, but have eternal life.

Planetary system


We learned before that our solar system is our group of planets (like Earth and Mars)
spinning around our star which is called the Sun.

We use the word solar just for our Sun, not for other stars.

For other stars with planets that spin (or revolve) around them,
we use the name planetary system.

French - one hundred


We just learned how to count to 99 in French! Wow!

What about numbers 100 and over?

100 in French is cent - sounds like son - /?/
For numbers higher than that, you just say the individual numbers afterward.
101 cent un - sounds like sont-on /?/

102 cent deux - sounds like son-doo /?/

103 cent trois - sounds like son-twah /?/

104 cent quatre - sounds like son-cat-uh-ah /?/

Ostrich


The Ostrich is the largest bird in the world.

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.

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 /?/

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!

Kiwi


The kiwi bird is a small bird that lives in a country called New Zealand.
It can't fly, just like the ostrich or penguin.

A kiwi bird is about the size of a chicken, but the kiwi egg
is about six times the size of a chicken's egg!

(from: wikipedia - kiwi)


One different thing about the kiwi is that it has nostrils at the very end of its beak.
It can use it's beak to smell the dirt and find small bugs or seeds to eat below the dirt.

Black Dwarf


We've now learned that our Sun is a Yellow Dwarf,
after it burns for 10 billion years it will turn into a Red Giant,
and after it burns for another 1 billion years it will turn into a White Dwarf.

That white dwarf will burn slowly for a very very long time,
over 10 Undecillion years (One undecillion is a 1 with 36 zeroes after it!),
then it will cool down and turn into a Black Dwarf.

That's such a long time, that no actual black dwarfs exist!
Scientists are just pretty sure that's what is going to happen some day.

Electroluminescence


Electroluminescence is a pretty fancy sounding word,
but all it really means is a way that some things give off light
when you run electricity through them.

Electro - for electricity
luminescence - a fancy way to say light

Some of the best chemicals for making this kind of light are doped semiconductors,
which we learned before are just two kinds of chemicals mixed together.

When the electricity flows through them, the photons (which are tiny particles of light)
go shooting off of the chemicals and make it glow.

Hedgehog


Hedgehogs look kind of like tiny little porcupines.

And just like porcupines, they have poky hairs on their back (called spines) made of keratin.

Their spines don't come out like a porcupine's quills, they are just sharp.

hedgehog
(from: wikipedia - hedgehog)

Hedgehogs also do a funny thing called anointing.
When they find something with a new smell in the wild,
they will lick and bite that thing, and then spit on their spines.

Scientists aren't totally sure why they do this,
but some think it is so they can hide their smell from other animals that want to eat them!

Matthew


The first books of the New Testament are the four Gospels.
The word gospel means good news, and these books in the bible
all tell about Jesus and the miracles he performed.

The first gospel is the book of Matthew.

In the book of Matthew, he tells of 23 different miracles that Jesus performed.

He healed blind and sick people, walked on water, calmed a wild storm,
and fed thousands of people from just a basket of bread and fish.

He tells of the story of Jesus birth, tells of the wise men visiting baby Jesus.
He also tells of Jesus dying on the cross, and being resurrected three days later.

Matthew started off as a tax collector, but became one of Jesus followers.

White Dwarf


We've now learned that our Sun is a Yellow Dwarf,
and that after it burns for 10 billion years it will turn into a Red Giant.

After that Red Giant burns for 1 billion years, it will turn into a white dwarf

A White Dwarf is much smaller than a Red Giant or Yellow Dwarf, but very thick.

The big star Sirius A has a very small neighbor Sirius B that is a white dwarf.

It's measurements are:
stellar classification: A1 (white)
luminosity class: V (main sequence, or dwarf)

So we can call it an A1V star, or a white dwarf.

If you look in the picture of Sirius A, you can see a very small white dot
that is the small white dwarf Sirius B.

Seventy one is sixty-eleven, and so on.

Photons


When you turn on a light bulb or use your flashlight, it makes things brighter.

But does light actually have parts?
Is it made up of little bits, or is it just light?

It turns out light is actually made up of something called photons.

Photons have no mass meaning they don't weigh anything like an atom does,
but they do move around and they are tiny little particles!

Porcupine


When you see a porcupine, it might look like a cute little animal,
but don't try to pet it unless you want to get poked!

Porcupines have quills, which look like long sharp needles that stick out from their backs.
The needles are actually made of keratin, the same as the spikes on a cat's tongue,
a turtle's shell, and rhino's horn.

The quills have little barbs on them, that are like small needles pointing the opposite way.
So when you get a porcupine quill stuck in you, it's really hard to get it out.
This helps the porcupine protect itself.

What happens when a porcupine pokes itself?

The porcupines have antibiotic medicine built right into it's skin,
so even if it falls out of a tree and pokes itself with a quill, it will heal up fast!
