Yesterday at school, I learnt something new.
It sounded so strange that I thought it must be untrue.
My teacher taught us about gravity, an extraordinary force,
That holds the universe together, and keeps the planets on course.
"Gravity," teacher said, "keeps things in their proper place.
It keeps people, buildings, air, and water from flooting into space.

When you throw a ball up into the air, gravity makes it fall to the ground.
Gravity, nature's invisible, most dominant force, works without a sound."
After I learnt about gravity, I was filled with great wonder,
The amazing things that gravity did, really made me ponder.
It's gravity that makes fruits from trees fall to the ground,
Instead of rolling into the sky, never to be found.

It's gravity that helps me to have a shower every day;
Without gravity, my both water would levitate, and glide away.
The Moon orbits around Earth because of gravity's power;
Gravity grabs rocks from a passing comet to bring a meteor shower.

I'm glad I know so much about gravity, but now I'm worried too --
If the force of gravity vanishes one day, what will I do?
I'm terrified that I'll soar into the air, and float into space,
And land on another star, in a scary, cold, dark place.
I asked Mama about this, but she just laughed and said, "No, No.
That's never going to happen, so don't you worry so."
But I'm still not fully convinced, and hope that Mama's right,
If she's not -- I can't bear to think of my plight!
