SUMMARY:

The present master's proposal aimed to develop and apply an Potentially Meaningful Teaching Unit (PMTU) for the study of mechanical collisions using a experimental apparatus known as the Gauss Cannon. With this PMTU, which was implemented in a first-year high school class at a private school in Recife, we sought to teach the concepts related to the study of mechanical collisions and magnetism in a playful and meaningful way, emphasizing the learning of concepts such as magnetic attraction, mechanical collisions, velocity, and the principles of energy conservation and linear momentum conservation Keywords: Potentially Significant Teaching Unit, Mechanical Shocks and Magnetism, Gauss Cannon.
The experimental activities were organized in a structured and sequential manner, aligned with the topics covered in the classroom, with the objective of observing, through experimentation, the learning process of the involved concepts. By studying through a didactic sequence—a methodological approach that systematically organizes the execution of an activity—students can benefit from a safe and structured environment, which significantly reduces anxiety-related factors and prepares them to engage in discussions on various topics. This demonstrates increasingly well-guided learning, fostering creativity, imagination, and student engagement. To assess the effectiveness of the educational product, we administered questionnaires before and after the implementation of the PMTU. The analysis of these questionnaires indicated progress in the learning process of concepts related to mechanical collisions, particularly in understanding the vector characteristics of interactions, the relationship between velocities before and after collisions in characterizing the type of collision, and the calculation of velocity and kinetic energy through linear momentum. Additionally, the experience highlighted that prior knowledge is fundamental in acquiring new ideas, as it enables students to construct scientific knowledge and develop skills.
