Genesis


Remember we learned about how the Old Testament is all about what happened before Jesus was born, and that you can split it up into 4 parts: Law, History, Poetry, Prophecy.

There are five books of Law, and they are:
Genesis, Exodus, Leviticus, Numbers and Deuteronomy.

The first book Genesis means beginning.

There are many well known people from this book that you might remember:

Adam & Eve - The first people God created.

Cain & Abel - Children of Adam & Eve.

Noah - Built the ark to avoid the flood.

Abraham - Made a promise with God, father of the Israelites.

Isaac - Abraham's only son, almost sacrificed but saved by an angel.

Jacob & Esau - Twins, Jacob gets renamed as Israel.

Joseph - Coat of many colors.

Neptune


We just learned about the planet of Uranus.

Neptune is the eighth and last planet in our solar system,
but it wasn't always that way!

(from: wikipedia - neptune)

For almost 100 years, Neptune was known as the last planet in our solar system.
Then in 1930, someone discovered Pluto!

For 40 years, Pluto was the furthest planet from the Sun in our solar system,
but then in 1979 it's orbit brought it closer to the Sun and Neptune became the furthest (and ninth) planet.

It was like that for 20 years and then switched back to Pluto being furthest.

Then in 2006, Pluto was reclassified as a dwarf planet,
making Neptune the furthest again.

French - We are surprised


We've now learned how to say I am happy,
you are sad, he is angry, and they are excited, in French.

Now let's learn how to say We are suprised.

We can break it up into the three words:
We - Nous - sounds like nooz /?/
are - sommes - sounds like sum /?/
surprised - surpris - Sounds like see-uh-puh-ee /?/


All together Nous sommes surpris sounds like noo-sum-see-uh-puh-ee.

Electrical Circuit


Now that we've learned about voltage, current and resistance,
we can try to understand an electrical circuit.

Remember what we've learned already by comparing electricity to water flowing through a pipe:
Voltage - The speed of the water flowing through
Current - How big around the pipe is
Resistance - A part where the pipe gets smaller and makes it tougher for water to get through

When people draw pictures to represent electrical circuits, they use special pictures and letters:
electrical circuit
(from: wikipedia - electrical circuit)

v with the circle and +- in it stands for voltage.
i with an arrow stands for current
R with the zig-zag lines stands for resistance

So if you think of it like a water hose, the faucet is starting at v and the voltage
is how much you've turned on the faucet. Just a drip or full blast?.

The current i is for how big around the hose is.
Is it just a regular garden hose, or a big fire truck hose?

The resistance R is if there are any kinks in the hose,
or if anything is stuck in the hose.

You can see that all those things together make the water come out of the end of the hose really fast or really slow!

Chameleon


Can you move your right eye without moving your left one?
Can you cross your eyes?
Can you have one look up and the other look down?

A chameleon can do all of these things!

There's no hiding from a chameleon, even if you're standing behind, above or under them, they can move their eyes and see you.

And if you're a bug, they use their super long tongue to reach out and grab you for lunch!

Chameleons are great at hiding too, when a bigger animal comes along.
They can change their body to all sorts of colors!

Facial Skeleton


Remember we already learned that the head bone or human skull is called the cranium,
and that the part in the back of your head that holds your brain is called the neurocranium

The part in the front that has your face is called your facial skeleton, viscerocranium or splanchocranium.

It's everything from your forehead to your nose to your cheeks and mouth.

Greenland


We just learned a little about the Central American Countries.

If you go North and East from the US or Canada, you will find a country called Greenland.
greenland
(from: wikipedia - greenland)

It is an island, and the largest island on the Earth that is not considered a continent.

At over 800,000 square miles, Greenland is larger than the largest US state Alaska (under 700,000),
but with less than 57,000 people, it's less populated than the least populated US state Wyoming. (over 500,000)

This is mostly because almost all of Greenland is covered in a big sheet of ice!
