This lesson is designed for the NEW AQA Trilogy Chemistry GCSE, particularly the ‘Structure & Bonding’ SoW.
 
The lesson begins with a recap on the differences between elements, compound and mixture, pupils complete a task and self-assess their work. Pupils are then introduced to the idea of covalent bonding and ionic bonding as two forms of bonding and are reminded how to draw the electronic configuration of an atom, including a reminder of the rules around filling energy shells.
 
Pupils will now watch a video on the formation of ions, whilst watching the video pupils will answer a set of questions and when finished pupils can assess their work using the answers provided in the PowerPoint. Next, pupils will be shown how to draw diagrams to demonstrate the formation of positive and negative ions, they can draw examples in their books for future reference. To assess their knowledge of this topic pupils will complete a set of questions including drawing a diagram to demonstrate the formation of an ionic bond between lithium and fluorine, this can then be self or peer assessed using the answers provided.
 
The last task is for pupils to use their periodic table to draw the electronic structure of the ions formed from a potassium, oxygen, magnesium and calcium atom. This work will then be assessed using the answers provided.
 
The plenary involves pupils picking a task, wither write a twitter message about what they have learnt or write a set of quiz questions to test peers on what they have learnt in the lesson.
