LESSON 3: The Force of GravityTime: 40 minutes
Lesson Overview
Before students can determine what makes a car move, they need a good understanding of movement and force. In Lesson 3, students will learn about one of the greatest forces of all—gravity. They will discover how gravity affects objects on Earth and compare the forces required to move toy cars uphill, on flat land, and downhill. They will also compare speed differences in these settings. Students will use science practice to make predictions, investigate and record their findings.
Lesson Objectives
By the end of this lesson, students should be able to:- Compare and contrast the speed of cars moving uphill, on flat land, and downhill.
- Compare and contrast the force needed to move cars uphill, on flat land, and downhill.
- Give examples of how gravity affects objects.
- Describe how gravity affects cars going uphill or downhill.
