Work and Energy
Students will define the relationship between force applied over a distance and the concept of energy.
Key Questions
- Explain how work is done when lifting a heavy box versus pushing a wall.
- Compare potential energy and kinetic energy using examples of a roller coaster.
- Assess how the amount of force and distance affect the work done on an object.

Introduction to Forces
Students will explore different types of forces (push, pull, friction) through hands-on activities and observe their effects on objects.
2 methodologies
Balanced and Unbalanced Forces
Students will investigate how balanced and unbalanced forces dictate the state of motion for any given object using simple experiments.
2 methodologies
Newton's First Law: Inertia
Students will explore Newton's First Law of Motion, understanding inertia and how objects resist changes in their state of motion.
2 methodologies
Force and Motion: Observing Changes
Students will observe how different strengths of pushes and pulls affect the speed and direction of objects, without formal calculations.
2 methodologies
Newton's Third Law: Action-Reaction
Students will explore action-reaction pairs and understand that forces always come in pairs.
