Standard IV - Universe
Standard: Students will understand the scale of size, distance between objects, movement, and apparent motion (due to Earth’s rotation) of objects in the universe and how cultures have understood, related to and used these objects in the night sky.
Objective 1: Compare the size and distance of
objects within systems in the universe.
Objective 2: Describe
the appearance and apparent motion of groups of stars in the night sky relative
to Earth and how various cultures have understood and used them.

The solar system consists of planets, moons, and other smaller objects including asteroids and comets that orbit the sun. Planets in the solar system differ in terms of their distance from the sun, number of moons, size, composition, and ability to sustain life. Every object exerts gravitational force on every other object depending on the mass of the objects and the distance between them. The sun's gravitational pull holds Earth and other planets in orbit. Earth's gravitational force holds the moon in orbit. The sun is one of billions of stars in the Milky Way Galaxy, that is one of billions of galaxies in the universe. Scientists use a variety of tools to investigate the nature of stars, galaxies and the universe. Historically, cultures have observed objects in the sky and understood and used them in various ways.
