CHAPTER
1
The Mysterious Movement
of the Moon
It is early in the morning on a school day. Lin sits
at the kitchen table. It is still dark outside, and
he is tired. It is hard to wake up on these dark,
cold mornings! Sleepily, Lin looks out the kitchen
window. The sky is just beginning to brighten.
Lin can see the moon. “It’s morning,” Lin thinks.
“Why is it still dark? And why is the moon still
in the sky?”
2
Just before dinner that evening, Lin walks his dog, Luna.
The sun is setting. It is starting to get dark outside. Lin again
notices the moon in the sky. But it is in a different place. Again,
he wonders why the moon is visible when it is not yet night.
He thought the moon only came out at night. The appearance
of the sky is changing all the time.
3
When he sits down to dinner, Lin looks for the moon through
the kitchen window. But the moon is not there! Lin saw the
moon when he walked Luna just a few minutes ago. He knows
it is in the sky. So why can’t he see it through the window
like he could at breakfast this morning? He knows he saw the
moon this morning when he was sitting in this same spot. He
was looking through this same window.
4
Lin thinks back to the beginning of first grade. The mornings
were bright and sunny, not dark. He walked the dog before
bedtime instead of before dinner because it was still light
outside later in the day.
“But where was the moon?” Lin thinks to himself. “Why can I
only see the moon sometimes? And why does it seem to move
from place to place?”
