This teacher guide outlines an engaging inquiry-based lesson focusing on the Law of Conservation of Mass. It details a hands-on experiment in which students observe a chemical reaction within a closed system (using a balloon on a flask) to witness the stability of mass. The guide specifies student roles, including Materials Manager, Data Recorder, and Safety Inspector, and provides a structured pedagogical flow with distinct timings for various activities such as a hook, core experiment, and class-wide data analysis. Additionally, it emphasizes collaborative teamwork and ensures that students actively participate in measuring and recording data during the experiment. The guide also includes steps for conducting the experiment, prompting students to predict and verify mass measurements, with opportunities for discussion and reflection on their findings regarding the conservation of matter.
