Sun, Moon and Tides

One of the models tells the time from the Sun during the day and the Moon at night. Another mimics the motion of bothe the Sun and the Moon across the sky on any day of the year, demonstrating clearly why the days are longer in summer and shorter in winter. The moon globe names all the seas, craters and Apollo landing sites and makes it clear why part of the Moon's surface can never be seen from Earth. Included also is a minibook packed with information and explanations about the relationship between the Sun, the Moon and the Tides.
