Who Turned Out the Lights?

 
Earth makes one complete rotation on its axis each day, or every 24 hours. During this rotation, one-half of Earth is facing the sun, experiencing day, while the other half is not facing the sun, experiencing night.
 
Remember when you practiced rotation a few pages ago? In that activity you pretended to be Earth. You rotated around your axis while a friend shined a light on you. You could easily see where it was daylight on Earth and where it was night.
 
In the next activity we will see how the things you do depend on the time of day.
 

Copy the chart below in your science journal. Under the yellow clock, write four things you do during the day. Under the grey clock, write four things you do during the night.
