As part of their Physics lesson, the students of the 5th Grade, with the guidance of their teachers, constructed a balance scale simulation using creativity, enthusiasm, and teamwork. The aim of the activity was to calculate masses by using weights of known mass.Through this hands-on and engaging learning experience, students had the opportunity to understand the basic principles of balance and equilibrium in a practical and enjoyable way, observing when and how a scale reaches a state of equilibrium.
