Video and supporting resources for two practical experiments exploring conservation of mass.
Investigate conservation of mass with two experiments for learners to explore the concept for GCSE and equivalent 14–16 courses. There are two parts to this video, the first is the reaction of magnesium with oxygen and the second is the reaction of calcium carbonate with hydrochloric acid. Additional resources including pause-and-think questions with answers, teacher notes, technician notes, integrated instructions, intended outcomes, follow-up worksheets and structure strips are provided to support your teaching.
Chapter titles: 00:09 Introducing conservation of mass; 01:29 Reaction of magnesium and oxygen; 04:31 Reaction of calcium carbonate with hydrochloric acid; 05:54 Calculating the change in mass; 07:20 Open and closed systems.
