Delve into the law of conservation of mass with this discrepant event-based demonstration. Students make predictions about the additive nature of 2 liquids, and then observe that volume is not conserved when the liquids are mixed. Students illustrate why the volume change upon mixing is not zero and answer big-picture questions that connect the concepts to real-world scenarios. This demonstration requires approximately 10 min and materials are sufficient for 5 demonstrations.
