I wonder how hot the sun is

At the very center of the sun, it is 27 million degrees Fahrenheit.

The Earth's center is estimated to be around 11,000 degrees Fahrenheit.

That is over 2,000 times hotter!

I wonder how to make a car

The cars that we drive around in are put together on something called an assembly line. An assembly line is where something is built one part at a time in stations.

Imagine a cookie decorating assembly line.

Person 1 puts the cookies on the line.

Person 2 puts the frosting on the cookies.

Person 3 puts the sprinkles on the frosting.

Ta-da! Cookies with frosting and sprinkles!

The same is done with cars - some stations are machines and some are people.

Here is a video that shows parts of a car assembly line.

Could a megalodon's teeth actually break a whale's skull?

First, take a look at the size of this extinct shark from millions and millions of years ago.

So, could a megalodon's teeth actually break a whale's skull? No.

WHAT?????????????

Hear me out. A megalodon COULD break a whale's skull, BUT it was the jaw strength we should be giving the whale-eating credit to.

OK, I will change my answer to "kind of".

I wonder why the birds make nests in trees instead of the ground

Nests are built in trees for safety. Being up in the trees keeps the parent birds, eggs, and hatchlings from being eaten by predators and from being stepped on.

There is, however a bird called the killdeer that does make its nest on the ground.

I wonder how many books are in the whole school

The short answer... too many to count.

Look around and you will see buckets of books, shelves of books and stacks of books!

Take a look at this bookshelf in Ms. Rands' classroom.

The top shelf alone has 195 books on it.

Here is a number that I can give you. There are 15,634 books in the library.

That is 156 hundred flats, 3 ten longs, and 4 ones cubes.

I wonder how tall the tallest person in the world is

I wonder what the center of a black hole is called
