This teacher guide provides an organized framework for a two-class lesson focused on the investigation of particle behavior in heated water and the concept of density. It outlines the necessary materials, safety protocols, and steps for conducting the experiment involving different liquids (water, glycerin, and rubbing alcohol). Students will engage in data collection, density calculations, and discuss the changes in particle composition during phase transitions. Key learning targets include understanding density as a characteristic property of matter, analyzing experimental data, and constructing evidence-based arguments regarding particle behavior. The guide emphasizes the relevance of these scientific concepts to real-world situations and provides an opportunity for students to connect their findings to larger scientific principles.
