Standard III - Solar System
Standard: Students will understand the relationship and attributes of objects in the solar system.
Objective 1: Describe
and compare the components of the solar system.
Objective 2: Describe the use of technology
to observe objects in the solar system and relate this to science’s
understanding of the solar system.
Objective 3: Describe
the forces that keep objects in orbit in the solar system.
Strategies
Science Benchmark
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.
