We live on the earth .During the day ,we can see the
sun in the sky . Sometimes we can also see the moon.
At night , the sky is dark . We can see stars. Sometimes we can also
see the moon.
The sun ,moon and stars are all objects, astronomers have been able to
discover a lot about space.
The pattern of a day
Every day ,the sun rises in the east.
It travels across the sky and sets in the -________________
west. It is highest in the sky at midday.
The Earth's axis is the line joining the north pole to the
south pole . It is as if there was a long stick passing
through the earth from top to bottom
Around the world
At any moment ,only the half of the earth that faces the sun
is in daylight. As the Earth turns, this part moves into
darkness . this is night-time
