This lesson is designed for the NEW AQA Trilogy Chemistry GCSE, particularly the ‘Chemical Analysis’ SoW.
Firstly, students will conduct an investigation which carries out flame tests to check for the presence of different positive ions. Pupils will need to follow the method provided and record their results in a table in their books, once this task is complete they can self-assess their work using the mark scheme provided.
Pupils will then watch a video on the use of sodium hydroxide solution in the test for positive ions, they will need to answer a set of questions using the information provided in the PowerPoint presentation. The answers to this task are provided in the PowerPoint so students can self-assess their work. Next, pupils will need to complete a flow diagram to demonstrate the steps involved in identifying a range of positive ions by using sodium hydroxide solution, this task can be self-assessed using the mark scheme provided.
To assess their knowledge of flame tests and use of sodium hydroxide solution in identifying positive ions, pupils will need to fill in the blanks in a summary table. This work can be self-assessed using the answers provided.
The next part of the lesson will focus on negative ions, firstly students will watch a video and will need to answer a set of questions using the information provided in the video. This work can self-assessed using the answers provided.
Lastly, students will practice writing ionic equations for reactions which lead to the identification of either positive or negative ions before a final set of summary questions. Answers to these tasks are provided for self or peer assessment.
The plenary task is for pupils to write a set of quiz questions to test their peers knowledge of what they have learned during the lesson.

I bought this to try out your resources as a colleague recommended you to me. But, to be honest, I didn't expect there to be errors in the precipitate colours in a resource that's being charged for. However, despite this, the activities are good for live or remote lessons.
