6.1.2/3: Solar System 3 Dimensions & Progressions

Unit 2

LESSON RESOURCES

Phenomena: Celestial objects revolve around the sun in elliptical orbits in the solar system.

Objective

Overview

Materials

● I can develop a model to describe the role of inertia and gravity in orbital motions of objects in our solar system.

● Have students watch the video of planets orbiting the sun. Ask students to write down observations as they are viewing the

Activity: Gravity & Inertia

Objective

Overview

Materials

● Students build a model using a string, washers, and a spool/or straw to show how inertia impacts planetary motion. Students view different variables, such as mass, or distance from an object on planetary motion. ● Students then read about orbital motion.
