WA.4. Earth and Space Science
ES1. Earth in Space
6-8.ES1. The Solar System: In prior years, students learned the implications of the spherical-Earth concept and Earth's relationship to the Sun. In grades 6-8 students study the Moon's changing phases and learn to distinguish between phases and eclipses. They also learn about other objects in the Solar System and how they are held together by a force called "gravity." Students also learn about the Sun's position in the Milky Way, which is just one of many galaxies in the universe. This broad overview of Earth in space will provide a useful framework for students to understand new discoveries in astronomy and new milestones in the exploration of space.
6-8.ES1C. Students know that most objects in the Solar System are in regular and predictable motion. These motions explain such phenomena as the day, the year, phases of the Moon, and eclipses.
6-8.ES1C.1. Students are expected to use a simple physical model or labeled drawing of the Earth-Sun-Moon system to explain day and night, phases of the Moon, and eclipses of the Moon and Sun.
