Squirrel

Squirrels are fun silly little animals, and exciting to watch as they run around climbing trees.

There are over 280 different types of squirrels, from the fox squirrels we see very often,
to the White tailed antelope squirrel and the Thirteen lined ground squirrel.

Squirrels live in pretty much every part of the planet, from super wet tropical rainforests to super dry deserts!
They pretty much only don't live in super freezing areas like Antarctica.

When you see a squirrel running around burying nuts in the ground,
that's the way they save up food for the coming fall and winter.
They are called scatter-hoarders, because they scatter their food and hoard it.

Sometimes the squirrels forget where they bury the nuts, and the buried nuts grow and turn into trees.
If a squirrel thinks it is being watched by someone who is going to steal their nuts,
some smart squirrels will even just pretend to dig a hole and bury the nut,
and then move on to another place!

Rectus abdominis

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

Last time we learned about the latissimus dorsi

Next up is the rectus abdominis.
These are the muscles in the front of your stomach, also called your abs or abdominal muscles.
You use them when you do bend forward, like you're doing a sit up.

Since these muscles sometimes look like six bumps on your stomach,
some people call them a six pack.

Netherlands

We just learned about the country of Finland.

The Netherlands is a country just Northwest of Germany.
The language there is Dutch and sometimes the country is just called Holland.

For dinner there you might have stamppot (mashed potatoes with vegetables) or snert (pea soup)!

People visit the Netherlands to go see their windmills and tulips.

Vincent van Gogh was a famous Dutch painter.

Wooden shoes are also an old Dutch tradition

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.
