Earth turns once each day and gifts us with a period of darkness and daylight. This valuable book is an excellent introduction to this earth science concept. Readers will review objects that may be seen in the sky during the day and night as well as events that usually happen during these times, such as attending school and going to bed. They'll also consider what daily events they enjoy the most and when these happen, aiding them in connecting these actions to time. Colorful photographs correlate perfectly with the accessible text.
