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.
Key Questions
- How does a stronger push change how fast a toy car moves?
- What happens to a ball's direction if you push it from the side while it's rolling?
- How can we make an object start moving, speed up, slow down, or change direction?

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
Newton's Third Law: Action-Reaction
Students will explore action-reaction pairs and understand that forces always come in pairs.
2 methodologies
Gravity and Weight
Students will analyze the concept of gravity as a force and differentiate between mass and weight.
