Atoms, elements and compounds

AQA GCSE Chemistry/Trilogy
C1 Atomic Structure and the Periodic Table
1.1.1 Atoms, elements and compounds
This lesson builds upon KS3 chemistry definitions of atom, element, compound and molecule as defined by the GCSE specification, but could also be used with more able KS3 classes.
Resources – Molecular model student kits (as many as possible). Students will use the lid as their ‘whiteboard’. This lesson could also be completely teacher-led through use of a visualiser.
The Powerpoint presentation structured and presented in order to help aid working memory and those with reading difficulties. However I hope it also allows scope for classes to extend their understanding through their own discussions and teacher-led questioning.
It builds up to the use of the models to understand the conservation of matter, although this is not stated as such.
Notes for the reasoning behind each activity are given with the slides.
