This lesson is designed for the NEW AQA Trilogy Chemistry GCSE, particularly the ‘Structure & Bonding’ SoW.
 
This lesson starts with a video on covalent bonding, pupils will need to watch the video and answer a set of questions. When pupils are finished their work can be marked using the answers provided. The next activity is a crossword on covalent bonding, this too can be self-assessed using the answers provided on the PowerPoint.
 
The next part of the lesson focuses on simple covalent molecules, firstly pupils are introduced to the idea that covalent structures are either simple molecules or giant structures. Pupils will be shown dot and cross diagram of a hydrogen molecule and asked to have a go at drawing a dot and cross diagram of a chlorine molecule. Once this work has been checked, pupils are then shown how to draw a dot and cross diagram of a double bond and triple bond (oxygen molecule and nitrogen molecule), it may be beneficial for pupils to draw these diagrams in their books for future reference.
 
The lesson now focuses on some of the properties of simple covalent molecules, then pupils will be asked to draw a dot and cross diagram to show the structure of water, methane and ammonia. Once this task is complete, students can assess their work using the answers provided on the PowerPoint presentation.
 
The final task is a true or false task, pupils are given a set of statements about covalent bonding. They will need to identify if true or false, this can be done as a whole class using white-boards or in their books.
 
The plenary task is for pupils to unscramble anagrams of words relating to the bonding topic.
