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.ES1B. Students know that earth is the third planet from the sun in a system that includes the Moon, the Sun, seven other major planets and their moons, and smaller objects such as asteroids, plutoids, dwarf planets and comets. These bodies differ in many characteristics (e.g., size, composition, relative position).
6-8.ES1B.1. Students are expected to compare the relative sizes and distances of the Sun, Moon, Earth, other major planets, moons, asteroids, plutoids, and comets.
6-8.ES1E. Students know that our Sun is one of hundreds of billions of stars in the Milky Way galaxy. Many of these stars have planets orbiting around them. The Milky Way galaxy is one of hundreds of billions of galaxies in the universe.
6-8.ES1E.1. Students are expected to construct a physical model or diagram showing Earth's position in the Solar System, the Solar System's position in the Milky Way, and the Milky Way among other galaxies.
