Unit 2

STANDARD 6.1.2

6.1.2 Develop and use a model to describe the role of gravity and inertia in orbital motions of objects in our solar system. MS-ESS1-1

CONCEPTS

SKILLS

●​ Role of Gravity & Intertia ●​ Orbital Motion of Objects

●​ Develop a Model

LEARNING PROGRESSIONS

●​ Gravity is a force that keeps smaller/less massive objects in orbit around larger/more massive objects ●​ Gravitational force of the sun causes planets and other bodies to orbit around it ●​ Inertia in the solar system is the tendency for planets to resist changes in their direction and speed of movement ●​ Gravity and Inertia working together are what keep the planets of the solar system in stable orbits ●​ Relationships and interactions between objects increases with mass increases ●​ Relationships and interactions between objects decreases as the distance increases ​ ​ VOCABULARY ●​ Celestial Object ●​ Planets ●​ Distance ●​ Scale ●​ Orbit ●​ Orbital Motion ●​ Ratio ●​ Gravity ●​ Inertia ●​ Earth orbits around the Sun and the Moon orbits around Earth. ●​ Celestial objects stay in orbital patterns around the sun. ​ ●​ Saturn has over 80 moons that orbit it. ​ ​ ​ ​ END OF UNIT COMPETENCY WITH LANGUAGE SUPPORTS ●​ I can use a model to describe the relationships and interactions between components of the solar systems including gravity and orbital motion. ○​ Language Supports: ■​ verbs (ie. have, be, belong to) ■​ connectors to show relationships (ie. as a result, therefore) ■​ If/then clauses (ie. Gravitational forces from planets cause smaller objects to ____. Gravitational force of the sun causes _______.) POSSIBLE PHENOMENA
