Lattitude & longitude

Could you imagine if there were a bunch of lines all over the Earth,
that people could use to make maps and figure out where things were at on the planet?

Well there aren't really lines, but people have made up imaginary lines called latitude and longitude.

(from: wikipedia - latitude)

latitude is the word we use for the lines that go side to side,
and longitude is for the lines that go up and down.

Using those lines you can tell exactly where a place is on the map!

For latitude, the equator is in the middle so it is at 0° latitude.
The North pole is at 90° (or 90°N), and the South pole is at -90° (or 90°S).

For longitude, the 0° mark is at the prime meridian.
You can go East all the way to 180° (or 180°E) and West all the way to -180° (or 180°W).

For example, Detroit, MI is located at: 42.35, -83.05

Apostle's Creed - Part 9

Apostle's Creed - we're getting there!

We've learned through Part 8 now.

I believe in God, the Father Almighty, maker of heaven and earth.
And in Jesus Christ, his only Son, our Lord
who was conceived by the Holy Spirit, and born of the virgin Mary,
suffered under Pontius Pilate, was crucified, died and was buried.
He descended into hell. On the third day He rose again from the dead.
He ascended into heaven and sits at the right hand of God the Father Almighty.
From thence He will come to judge the living and the dead.
I believe in the Holy Spirit,

Here's part 9:

the holy Christian Church, the communion of saints,


(from: wikipedia - apostle's creed)

This means you believe in Christian people getting together and worshiping God together.

Planet Venus

We've already learned about the planet Mercury,
so let's move on to the next planet in our solar system: Venus!

(from: wikipedia - venus)

Venus is the second closest planet to the sun, right between Earth and Mercury.

It's the hottest planet in our solar system, at over 850 °F!

Even though it's close to the same size as Earth, you wouldn't want to live there.
The clouds around the planet are made of sulfuric acid which would burn your skin if you touched them.

Besides the moon, Venus is the brightest planet in our sky at night.

French - Cow, chicken, pig

We already know that in French, dog is chien and cat is chat.

Now let's learn about some farm animals!

cow - vache - sounds like vash /?/
chicken - poulet - sounds like pooh-lay /?/
pig - porc - sounds like pah-uh /?/

Also in French cows say meuh, chickens say coco-rico (co-co-uhee-co), and pigs say groin (guh-oo-ah)!

Binary

We just learned about And Or Logic Gates.

When we talk about letters and words, we know that A is a letter,
and Apple is a word with the letters A, p, p, l, e.

For numbers, instead of saying letters we call them digits So the number 174 has the digits 1, 7, 4.

The numbers we use every day go from 0 to 9.
The digits are: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
(The number 10 uses the digits 1 and 0.)

Since there are ten digits, we use the word decimal.

What if we only had two digits to use, 0 and 1?

Could we still make numbers?
Yes!

We can make the numbers: 0, 1, 10, 11, 100, 101, 110, 111 and so on!
Since we're only using 2 digits, we use the word binary (like bicycle which has two wheels)

When we want to match up our decimal numbers to our binary numbers,
we just put them in the same order.

binary 0, 1, 10, 11 is the same as decimal 0, 1, 2, 3
So b0 = d0, b1 = d1, b2 = d10, b3 = d11 and so on!

We already learned about how computers use 1 and 0 to turn lights on and off on your computer screen.

The whole computer uses just binary numbers to do all the math to turn those switches on and off.

Just think, giving a computer a number like: 1110 can be like telling it to turn 3 lights on, and the other one off!

Coyote yips

We just learned about the Komodo Dragon.

Coyotes are animals like dogs that live in North and Central America.


(from: wikipedia - coyote)

They are mostly nocturnal which means they sleep during the day
and hunt for food at night.

Even though a coyote is like a dog, their howl doesn't sound like a dog or wolf howl.
It's a very high sound, and can almost sound like a bird, and some people say it sounds like yip yip or yi-yi

Patella

The patella is the kneecap bone, right at the bottom of your femur.

(from: wikipedia - patella)

It is the small bone right at the point of your knee.
