story "How the Chipmunk Got Its Stripes" and then answer
Numbers 1 through 8.
ago, the Earth was covered in darkness. None of the creatures living
there knew what daylight looked like.
One day, all of the animals of the forest gathered together in a clearing.
They wondered if it would be better to remain in darkness, or if it
would be better to also have light. Deer, Chipmunk, Raccoon, Wolf,
Bear, and many other creatures climbed to the top of the highest mountain.
The mountain stood so tall that there were no trees on its top, and
it was covered only with rocks. Millions of stars blinked in the dark
sky overhead. The biggest and most powerful animal in the forest was
the bear, and he was the first to reach the mountaintop. Bear stood
on the highest peak, looked out over the forest below, and argued
for remaining in darkness. He said that the creatures of the forest
would be able to sleep better in darkness because there would be no
light to keep them awake. Most of the other animals were afraid, and
they agreed with Bear. Raccoon said that he did not mind the darkness
because he was so smart that he could find plenty of food, even in
the dark. Wolf was easy to please, too. She didn't mind the darkness
because she could howl in darkness or in light.
But one animal did stand up to Bear. Chipmunk, the smallest of the
animals, argued that it would be better to have both light and dark.
Chipmunk was very clever. As Bear continued to argue for darkness,
she made many good arguments for light.
Slowly, the night passed. Bear grew tired of talking, but Chipmunk
chattered on and on, as if she had all of the energy in the world.
As the other animals dropped off to sleep, one by one, Chipmunk kept
arguing. Finally, the first sunrise ever seen by the animals appeared
over the top of the mountain. They woke up and were amazed by what
Chipmunk began to dance from rock to rock. Bear became angry because
he didn't get his way. He roared loudly and ran after Chipmunk. He
chased Chipmunk all the way down the mountain. Bear was fast, and
he reached out his giant paw to grab Chipmunk. Chipmunk got away,
but not before Bear managed to scratch her back with his long claws.
And that is why, to this day, you can see stripes on Chipmunk's back!

article "Amazing Black Holes" and then answer Numbers 9
How many things can you see in the night
sky? A lot! On a clear night you might see the Moon, some planets,
and thousands of sparkling stars.
You can see even more with a telescope. You might see stars where
before you only saw dark space. You might see that many stars look
larger than others. You might see that some stars that look white
are really red or blue. With bigger and bigger telescopes you can
see more and more objects in the sky. And you can see those objects
in more and more detail.
But scientists believe there are some things in the sky that we will
never see. We won't see them with the biggest telescope in the world,
on the clearest night of the year.
That's because they're invisible. They're the mysterious dead stars
called black holes.
You might find it hard to imagine that stars die. After all, our Sun
is a star. Year after year we see it up in the sky, burning brightly,
giving us heat and light. The Sun certainly doesn't seem to be getting
old or weak. But stars do burn out and die after billions of years.
As a star's gases burn, they give off light and heat. But when the
gas runs out, the star stops burning and begins to die.
As the star cools, the outer layers of the star pull in toward the
center. The star squashes into a smaller and smaller ball. If the
star was very small, the star ends up as a cold, dark ball called
a black dwarf. If the star was very big, it keeps squashing inward
until it's packed together tighter than anything in the universe.
Imagine if the Earth were crushed until it was the size of a tiny
marble. That's how tightly this dead star, a black hole, is packed.
What pulls the star in toward its center with such power? It's the
same force that pulls you down when you jump the force called
gravity. A black hole is so tightly packed that its gravity sucks
in everything even light. The light from a black hole can never
come back to your eyes. That's why you see nothing but blackness.
So the next time you stare up at the night sky, remember: there's
more in the sky than meets the eye! Scattered in the silent darkness
are black holes the great mystery of space.
