KS3 ~ Year 8 ~ Group 7 - The Halogens

This lesson is designed for the KS3 Year 8 Science course, specifically the C2 1.1 unit on ‘The Periodic Table’.

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 an introduction to the elements found within Group 7 of the Periodic Table - the Halogens. Students will learn about some of the properties of these elements before each being given some information on the physical properties of one particular halogen. Students will then need to walk around the room and share information with each other in order to complete a summary table. This work can be self-assessed using the mark scheme provided.

Students will now need to focus on identifying trends with the halogen group, students will be given the melting points and boiling points of the halogen elements. Using this data they will need to answer a set of questions, this task can then be self-assessed using the mark scheme provided.

The next part of the lesson will focus on displacement reactions which occur amongst halogens, students will be shown a diagram which demonstrates how a more reactive halogen will displace a less reactive halogen. Students will now assess their knowledge of this topic by completing a set of word equations, this work can the be self-assessed using the mark scheme provided.

The plenary activity requires students to ‘Pick a Plenary’ - either summarise what they have learned in three sentences or write a definition for a set of key words which were 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 :)
