This lesson is designed for the NEW AQA Trilogy Chemistry GCSE, particularly the ‘Chemical Analysis’ SoW.
 
The lesson begins with a ‘Think > Pair > Share’ task where students are required to discuss sectors which must reply upon efficient and effective instrumental methods of chemical analysis. After a short class discussion, the teacher can discuss the importance of instrumental analysis for environmental and health care sectors.
 
Students will now be shown the difference between qualitative and quantitative methods of chemical analysis. They will then be given a set of statements, students will need to sort these statements into either advantages of disadvantages of instrumental methods of chemical analysis vs. traditional methods. Pupils will need to self-assess their work using the answers provided in the PowerPoint.
 
Next, students will watch a video on flame emission spectroscopy and will need to use information provided in the PowerPoint to answer a set of questions. This work can be self-assessed using the answers provided. Following this, students will be provided with a set of information about this process, they will need to use this information to answer a set of questions. Their answers to these questions can be self-assessed using the mark scheme provided.
 
Lastly, pupils will be shown a diagram showing the results of flame emission spectroscopy tests for different metals.
 
The plenary task requires pupils to write a Whatsapp message about what they have learned during the lesson.
