Balancing combustion equations (Structured powerpoint for students to edit)

This is an 8 slide structured powerpoint for students to edit. It looks at balancing simple equations. It deals, as you’d expect, with numbers of molecules, numbers of atoms, subscript, conservation of atoms. I wrote it to accompany a GCSE module on combustion and air pollution. It is in the form of a workbook where students can edit the powerpoint presentation; moving atoms around (copying and pasting as necessary). There is a worked example to start with and the slides get harder. It works well on a smartboard. For lower ability students it is better done in smaller chunks. It could be used as a homework if put on a VLE. A powerpoint with the answers is included (useful for self/peer marking).
