Daniel

We've now learned about God's prophets Isaiah, Jeremiah and Ezekiel
who all warned of the coming exile and conquer from the Babylonian king Nebuchadnezzar.

During the exile, God chose another prophet named Daniel.

God gave Daniel the ability to understand people's dreams,
and the kings of Babylon liked Daniel because he helped them understand their dreams.

Daniel stayed faithful to God, even when it was against the law for him to do it.
Even though the kings liked Daniel, there were some people that did not like him,
and they got Daniel in trouble for praying to God when it was against the law.

They threw Daniel into a big pit filled with hungry lions, called the lion's den!
But God protected Daniel, and the lions did not eat him.

The king saw how powerful God was and how faithful Daniel was,
and he told the whole kingdom that they should worship God!

Luminosity Class

We just learned that when scientists want to measure how hot a star is,
they use something called stellar classification.

When they want to measure how bright a star is,
they use something called absolute magnitude.

Looking at both a star's temperature (heat) and it's luminosity (brightness),
scientists also come up with something called luminosity class or spectral classification.

Luminosity classes are named with both a number (roman numerals like you might see on a fancy clock)
and also a name, like a supergiant or subdwarf.

The luminosity classes from biggest to smallest are:
0 - hypergiants
I - supergiants
II - bright giants
III - normal giants
IV - subgiants
V - main-sequence stars (dwarfs)
VI - subdwarfs
VII - white dwarfs

Electrodes

Remember that an electrical conductor is something that electricity goes through very well, and a SuperConductor is really super at handling electricity.

And a semiconductor is something that electricity goes through, but not very well.

Sometimes you want to connect a power source like a machine at a doctor's office,
to a semiconductor (like a person!) for some medical tests.

When you hook a good conducting wire up from a power source to a semiconductor,
that wire is called an electrode.

We use electrodes in all types of places from doctor's offices, to car batteries, to science labs.

Manatee

We just learned about Hippo Sunscreen.

The manatee is a large animal that lives in the water.

Some people also call it a sea cow because it is so big,
and there are legends that people used to think they were mermaids.

When a manatee blinks, it doesn't an eyelid like a human does,
it just has muscles around it's eye that close.

Try making a small circle with your fingers, and then close it up tight.
That's sort of how their eyelids work!

Trapezius

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

Last time we learned about the pectorals

Next up is the trapezius.

The trapezius, which are sometimes just called traps
are used when you lift your arms over your head,
when you try to touch your elbows together behind your back,
or when you fold your hands behind your back.
