KS3 ~ Year 8 ~ Metal Displacement Reactions

This lesson is designed for the KS3 Year 8 Science course, specifically the C2 1.2 unit on ‘Metals & Other Materials’.

For more lessons designed for KS3 and KS4 please visit my shop at: https://www.tes.com/teaching-resources/shop/SWiftScience.

The lesson begins with a recap on the reactivity series, students will be asked a seris a questions about certain metals found within the series. Students should be able to identify the metals based upon knowledge learned in previous lessons, once complete this task can be self-assessed using the mark scheme provided.

Students will now be introduced to the idea of a ‘displacement reaction’ as a reaction where a more reactive metal found in the reactivity series will displace a less reactive metal. An example is shown - aluminium oxide + iron -> aluminium oxide + iron. Students will then be give a set of reactions, without the products written in, they will need to decide whether a displacement reaction will take place or not. This work can then be marked and corrected using the mark scheme provided.

Students will now complete an investigation ‘Competition in Metals’. Students will follow the steps provided on the investigation worksheet to identify whether a displacement reaction has occurred between a number of metals + metal solutions. Students will fill in a results table as they go, noting down any observations as well as identifying if a reaction took place or not. Students can check their answers against the example results table found in the PowerPoint presentation.

Lastly, students will complete a ‘True or False’ task, they will be given a set of statements and will need to identify whether they are true or false. This work can be peer or self assessed using the mark scheme provided.

The plenary task requires students to complete a sentence starter, from the choice provided, in order to summarise what they have learned this lesson.

All resources are included at the end of the presentation. Thanks for looking, if you have any questions please let me know in the comments section and any feedback would be appreciated :)
