In this activity, students will engage with the concept of force by interacting with a classroom door. Through a series of exercises, they will observe and analyze the physical effort involved in both pulling and pushing the door. The aim is to help students understand how forces affect movement, encouraging them to reflect on their observations and the underlying principles of force. They will engage in discussions about the nature of movement, physical effort, and the concept of force itself, fostering curiosity and deeper inquiry into how objects behave in response to applied forces.
