Conservation of mass

This resource is aimed at KS3 students and is useful as it covers the following learning objectives...

• Identify what is conserved during changes of state and chemical reactions
• Explain the conservation of mass in chemical reactions
• Calculate masses of reactants and products

There are differentiation opportunities for lower and higher ability (check the green challenge questions). I have also included feedback boxes, in which you should put students names to keep individuals engaged and ready to learn and feedback.

There is also a practical included in the lesson, with clear instructions and health and safety requirements that students must follow.
