Lina looks at the night sky.
She sees the bright moon.
She wants to see the moon's craters.
The stars shine above her.
Lina feels very happy today.
She calls her grandpa for help.
Grandpa comes to her right away.
He asks, What do you see?
Lina says, I see the moon.
She says, I want to see more.
Grandpa smiles and nods to her.
He has an old tube.
He says, We can build a telescope.
Lina is excited to help.
They start to plan together.
