This detailed and engaging lesson uses a range of tasks, discussion points and quick competitions to explore how the structure of metals is related to their properties. The lesson begins by providing the melting points for four metals and challenging the students to work out why mercury would be considered to be the odd one out. This task enables students to recognise that most metals are solid at room temperature and then the next part of the lesson guides students through explaining how this is related to the structure. The range of quick competitions are used to maintain engagement but also to introduce new terms such as lattice and delocalised so that students can recognise these in descriptions and use them accurately in their own. Students will recall that metals are good conductors of electricity and heat and now will be able to explain this with reference to the free electrons. Progress checks are written into the lesson at regular intervals so understanding can be checked at critical points and misconceptions addressed. The final part of the lesson makes link to related topics such as alloys and naming compounds.
This lesson has been written for GCSE aged students.
