Original Prompt

activity to analyze chemical vs. physical changes, using the concept of solubility somewhere, relating to these standards: 3.2.5.D Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved. 3.2.5.E Conduct an investigation to determine whether the mixing of two or more substances results in new substances.

This learning activity focuses on the exploration of physical and chemical changes. Students aim to distinguish between these two types of changes and understand the principle of conservation of matter, which states that the total mass remains constant through various transformations. The document outlines a step-by-step investigation involving dissolving sugar in water, mixing baking soda and vinegar, and observing ice melting. Key vocabulary includes definitions for physical change, chemical change, solubility, and conservation of matter. Through guided observation and analysis, students will collect data about mass before and after changes, reinforcing their understanding of the concepts presented.
