Content split over 7 lessons (lessons in our school are 40 minutes so can condense material for longer lessons if required)
All exam questions have been removed for copyright purposes
All extension questions available on each slide
Answers all underneath each slide
Support also available where necessary
AfL sections and mini quizzes
Reducing the need for photocopying
Homework
Homework can also be used as extension sheets in lessons - or for higher ability students

EXTRA LESSONS INCLUDE (as we teach it anyway in our school to help with A-level) Molecular to empirical conversion, empirical to molecular conversion, empircial formula practical and balancing equations with skittles.
