The listing, DISCOVERY WORKS unit B - SUN, MOON AND EARTH has ended.

Paperback text for 5th grade, 122 pages, illustrated, consists of 80 page text and a 42 page science handbook.
This unit focuses on the causes of day and night, the causes of the seasons and the changes (phases) in the Moon’s appearance. The unit begins with investigations of the reason for day and night. Students will model the rotation (spin) of the Earth about its axis to demonstrate the 24-hour cycle of one rotation and observe day and night from Earth. Students will then model the Earth’s revolution or orbit around the sun on an inclined axis (23.5 o) to recognize the reason for the seasons. Students will observe and describe changes (phases) in the appearance of the Moon over a lunar cycle (approximately one month). Students will recognize that the positions of the Earth, Moon and Sun are predictable and that each “celestial (relating to the sky) body” moves in a predictable pattern. By having a deeper understanding of these patterns, we have made technological advances such as telescopes, periscopes, microscopes and even eye glasses to have a better “view” of the world around us and improve our quality of life.
