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!

Old Testament


We just learned a little about the Old Testament and New Testament.

The Bible can seem like a really huge book if you look at the whole thing.

But if you can look at it and can understand the different parts, it can be less confusing.

The Old Testament can be looked at in four sections:
Law, History, Poetry, Prophecy

There are 5 books of law, 12 books of history, 5 books of poetry,
5 books of major Prophets, and 12 books of minor prophets.

We'll learn more about these next time!

Uranus


We just learned a little about Saturn.

Uranus is the third biggest planet in the solar system and almost the furthest from the sun.
It is over 14 times bigger than Earth

(from: wikipedia - uranus)

The most interesting thing about Uranus is the way it rotates or spins.
The way Earth and the other planets spin around, you can think of them like spinning tops orbiting the sun.

But Uranus doesn't spin like a top, it acts more like a ball rolling on the ground.
The orbit is completely sideways!

This means that for half of it's year, it's South Pole is facing the sun,
and for the other half, it's North Pole is facing the sun.

Since a year on Uranus is 84 Earth years long, that means it's sunny in the North Pole for 42 years!

French - They are excited


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

Now let's learn how to say They are excited.

We can break it up into the three words:
They - Ils - sounds like eels /?/
are - sont - sounds like sown /?/
excited - excité - Sounds like ex-ee-tay /?/


All together Ils sont excité sounds like eel-sown-ex-ee-tay.

Resistance


Remember we said before that the three basic parts for most of the electricity that we see every day are:
Voltage, current, and resistance.

We can learn about electricity by comparing it to how water flows through a pipe.
We learned that voltage is like the speed that the water is going.
and that current is like the size of the pipe.

You can think of the Resistance as anything in the pipe that would slow down the water.

So if the pipe got smaller in the middle, that would make it so not as much water could flow through.
