Shadrach, Meshach, Abednego

During the time of the prophet Daniel the bad king
who ruled over God's people made it against the law to pray to God.

He even made a giant gold statue of himself and told everyone to worship it!

There were three other of God's prophets at that time called Shadrach, Meshach and Abednego.
They refused to worship the golden statue of the king,
and for that the king demanded that they were thrown into a giant fiery oven!

But when they were thrown in there to be burned up,
they were not harmed at all, God protected them so not even their clothes got burned.

Hertzsprung–Russell diagram

Hertzsprung–Russell diagram might be a difficult thing to say or remember,
but it's really just a very useful thing to help you remember
the things we've been learning about stars.

Since the name is so long, some people just call it a H–R diagram or even just HRD.

We learned about stellar classification, absolute magnitude and luminosity class

The HRD is a picture map you can use
to help understand how all of those things fit together.


(from: wikipedia - hertzsprung-russell diagram)

It was invented about a hundred years ago by two scientists,
named Ejnar Hertzsprung and Henry Norris Russell.

French - counting to forty nine

We just learned how to count to 39 in French, let's keep going!


40 quarante - sounds like cah-uh-on-t /?/
41 quarante et un - sounds like cah-uh-on-t ay un /?/
42 quarante-deux - sounds like cah-uh-on doo /?/
43 quarante-trois - sounds like cah-uh-on twah /?/
44 quarante-quatre - sounds like cah-uh-on coo-aht /?/
45 quarante-cinq - sounds like cah-uh-on sah /?/
46 quarante-six - sounds like cah-uh-on see /?/
47 quarante-sept - sounds like cah-uh-on set /?/
48 quarante-huit - sounds like cah-uh-on soo-ee /?/
49 quarante-neuf - sounds like cah-uh-ont nef /?/

Anode and Cathode

We just learned that an electrode is pretty much just a wire
that has electricity going through it.

If you look closely on a battery, you should see a plus (+) and minus (-) sign.
This is for the positive (+) and negative (-) parts of the battery.

When you hook a wire up to both ends of the battery, that wire is an electrode.

The wire touching the negative (-) part of the battery is called the anode,
and the wire touching the positive (+) part of the battery is called the cathode.

Those words really just mean which way the electricity is flowing.


(from: wikipedia - rechargable battery)

Electrons are negatively charged, and the electrical current
flows from the negative (-) anode to the positive (+) cathode.

Armadillo

We just learned a little about the Manatee.

Armadillos are tough little armored animals!

The name armadillo is Spanish for little armored one.
Their armor is made up of bone, covered up in scutes,
like the scutes on a turtle shell.

Some armadillos can roll up in a ball to protect themselves.

(from: wikipedia - southern three banded armadillo)

Armadillos come in all shapes and sizes, from the pink fairy armadillo
which could fit in the palm of your hand:

To the giant armadillo, which is the size of a pig!

(from: wikipedia - giant armadillo)

Another interesting thing is that when the nine-banded armadillo has babies,
it always has identical quadruplets!

Four baby armadillos that are exactly the same, every time!

Latissimus Dorsi

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

Last time we learned about the trapezius

Next up is the latissimus dorsi.

These muscles are sometimes just called lats.

You use your lats when you pull your arms down from the sky like doing a chinup,
when you pull your arms toward your body like opening a door,
and when you pull your arms up from the ground like picking something up.

Finland

We just learned about the country of Denmark

Finland is a country in Northern Europe, right between to Sweden and Russia on the other side.

Finland people love to sit in really hot small houses called saunas
