This lesson is designed for the NEW AQA Trilogy Chemistry GCSE, particularly the ‘Structure & Bonding’ SoW.
 
The lesson starts with students being introduced to the regular, crystal structure of a metal. To demonstrate the formation of metal crystals pupils can complete a simple practical activity whereby they place a piece of copper wire in silver nitrate solution, a displacement reaction occurs and silver metal crystals begin to form on the surface of the copper. Pupils can complete this task using the set of instructions included on the PowerPoint slide and write down their observations in their books.
 
The next part of the lesson focuses on linking the structure of a metal to it’s properties, once this has been demonstrated to students using the information and diagrams included in the PowerPoint presentation they can copy and complete a worksheet to assess what they have learned. Once this task is complete students can assess their work using the mark scheme provided.
 
Now pupils will look at metal alloys, firstly pupils will watch a video and answer a set of questions. Pupils can then self-assess their work using the answers provided.
 
The last part of the lesson is on the properties of metals and how their properties relates to their uses, each student will be given a card of information describing a property of a metal. Pupils will walk around the room discussing the information they have on their card with others and using each other they should be able to complete a table of properties in their books.
 
The plenary task requires pupils to come up with three facts, two key words and a question to test their peers on the topic of metallic bonding.
