This lesson will introduce students to Sir Isaac Newton, Aristotle and Galileo. As students learn about and experience Newton's 1st Law of Motion, they will explore gravity, force and inertia. (Appropriate for grade levels 4-8 with extension activities that teachers can use after the lesson is completed.)
Science Standards:
4.PS.2: Energy can be transferred from one location to another or can be transformed from one form to another
5.PS.1: The amount of change in movement of an object is based on the mass of the object and the amount of force exerted
6.PS.4: An object's motion can be described by its speed and the direction it is moving
7.PS.3: Energy can be transformed or transferred, but is never lost
7.PS.4: Energy can be transferred through a variety of ways
8.PS.2: Forces can act to change the motion of objects
STEM Emerging Technology Connections:
Hypersonics: This lesson on Newton's First Law of Motion, while simple, connects to the DoD's "Hypersonics" critical technology area. Understanding inertia, which governs an object's tendency to stay in motion, is crucial for designing hypersonic vehicles that can maneuver at extreme speeds. The lesson's activities, though using everyday objects, demonstrate the concept of inertia and its effect on trajectory, laying the groundwork for understanding the complexities of hypersonic flight and guidance systems.
