Use evidence to support that the gravitational force exerted by Earth on objects is directed toward the Earth’s center.
In this lesson, students model the solar system and analyze Earth’s place in the system as well as how the force of gravity causes the planets to move around the sun in predictable, regular paths. This page serves to highlight the key components of this lesson.
In this unit, students use sleds and roller coasters to explore the relationship between energy, forces, and motion. In this lesson, students apply what they know about energy and forces to engineer a roller coaster. This page is a high-level extract of this lesson.
