We enjoy sunrises and sunsets as the earth spins and carries us into and out of the sun’s light. If you lived on the moon, which spins more slowly than the earth, there would be two weeks of daylight and two weeks of night! This book explains in clear, easily understood language and with a simple experiment to demonstrate, what makes day and night.
"Accompanied by NASA photographs and Dorros's colorful, lively drawings, the text explains the Earth's rotation in clear and simple terms. An experiment using a lamp as the sun further clarifies the principles introduced."-Booklist
