Earth, Moon, and Sun, Third Edition

This unit helps students distinguish between the apparent motions of the Sun and Moon versus the actual motion of Earth. In Solar and Lunar Journals, students record daily observations about time and position of sunrise and sunset, moon shape, daytime visibility, and elevation. Their data point to interactions among the Earth, Sun, and Moon that explain day and night, seasons, moon phases, length of day, tides, and more. Scale models of the solar system dramatize its massive distances and its planets' relative sizes. The final activity puts students onboard famous ocean voyages, relying on celestial navigation to stay on course. (13 Activities)
