In this lab experience, students engage in an investigation to prove that matter cannot be created or destroyed via chemical reactions, only converted from one form to another despite visual evidence that they might interpret as contrarian to the Law of Conservation of Mass. Students observe that the precombustion mass of sugar samples are equal to, or negligibly different than, the post-combustion masses of the sugar samples. Students infer from this observation that mass is conserved throughout chemical reactions and that matter is not created or destroyed, but transformed from one form to another.

Safety: Before conducting the lab, review with the class the safety precautions on the student page. Then discuss any safety precautions that are specific to your science laboratory or classroom. Good ventilation is required since combustion reactions can generate a large amount of smoke. Caution students that they should wait for their test tubes to cool for approximately 10 minutes prior to weighing them and that hot glass looks just like cold glass.
