Ks3 ~ Year 8 ~ Group 1 - The Alkali Metals

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.

This lesson begins with an introduction to the elements found within Group 1 of the Periodic Table - The Alkali Metals. Students will also learn some of the properties of the Alkali Metals which make them similar to other metals.

Students will now focus on the reaction of alkali metals with water, students will learn what happens with lithium is placed in water - including the word equation for this reactions. After learning this, students will then need to copy and complete the word equations of other alkali metal reactions with water. This task can then self-assessed using the mark scheme provided.

Students will now draw a table in their books before watching a video on the different reactions of Group 1 metals with water. Students will need to note down observations whilst watching the video. After completing this task, students are asked to ‘Think > Pair > Share’ their ideas about how they think rubidium and caesium will react with water. After this task, students can assess their work and also watch a another video to find out if their predictions about rubidium and caesium were correct.

The next activity requires students to read a paragraph of information about the alkali metals, students will then need to answer a set of questions using this information. Once complete students can self-assess their work using the answers provided on the PowerPoint.

The last activity is a ‘True or False’ activity, students will need to decide whether the statements are correct or not. The answers are provided for this task so students can check their work.

The plenary activity requires students to write down three facts, three key words and one question to test their peers on 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 :)
