Other Prophets

We just learned about Shadrach, Meshach and Abednego.

God called on many people to be prophets for him through the years.

We've learned about the ones who wrote some of the big books of the bible,
Daniel, Ezekiel, Jeremiah and Isaiah.

They are called the major prophets because they wrote the longest books of prophecy.

There are 12 other prophets called minor prophets not because they weren't important,
but because the books they wrote just weren't as long.

Hosea, Joel, Amos, Obadiah, Jonah, Micah,
Nahum, Habakkuk, Zephaniah, Haggai, Zechariah and Malachi
all delivered prophecies from God to his people.

Some of them warned of the coming exile, some cautioned people to listen to God after the exile,
and some told about the future when Jesus would come along.

Yellow Dwarf

We've learned so much about how to measure stars now!

We now know that:
- stellar classification is how hot the star gets, and uses letters and colors, like M and red
- absolute magnitude is how bright a star is, and uses numbers from -15 to 20.
- luminosity class is heat and brightness together, and uses numbers and names like I and supergiants.
- Hertzsprung-Russel diagram is like a map for understanding all of those measurements.

Now that we understand all of that, we can understand more about the stars in our universe!

The sun in our solar system has a stellar classification of G (yellow)
and a luminosity class of V (main sequence or dwarf)

So some people call our sun a Yellow Dwarf,
and others call it a GV, but they mean the same thing!

Yellow Dwarf stars are about 9,000 degrees, and burn for 10 billion years!

French - counting to fifty nine

Doping Semiconductors

We just learned about what a Anode and Cathode are.

We learned a while back that semiconductors are chemicals that do not conduct electricity very well.

Some scientists discovered a crazy thing, that if you mix up a semiconductor with another type of chemical,
then when you zap it with electricity it becomes a good conductor!

This is called doping or adding impurities into the semiconductor.

Remember we said silicon was a semiconductor.
The chemical arsenic can be added to silicon for doping.

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.


(from: wikipedia - rectus abdominis muscle)

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
