Lesson 1 Earth’s Motion Around the Sun – We investigated Earth’s movements which are rotation or spinning on its axis and revolution or moving around the Sun. We discovered that the Earth spins counterclockwise on its axis. Our evidence is that the Sun, Moon, and stars seem to move from east to west across the sky. Our evidence of revolution is the seasonal patterns of change throughout the year, including length of daytime, and the amount of sunlight different locations on Earth receive. The evidence of how the curve of Earth’s surface affects temperatures on Earth includes the fact that it is colder at the poles and warmer at the equator. Regions near the poles receive less solar energy than regions near the equator because the curved surface causes sunlight to be less concentrated and more spread out the farther you travel from the equator.
