Form 3: First-Class Levers
In this engaging activity, students will explore the mechanics of first-class levers by constructing simple machines using everyday materials, allowing them to understand the principles of force, fulcrum, and balance while solving real-world problems. Get ready to experiment and discover how levers can make work easier!
