This lesson is designed for the KS3 Year 8 Science course, specifically the C2 1.3 unit on ‘Separation Techniques.

More Biology, Chemistry and Physics resources can be found in my TES Shop: https://www.tes.com/teaching-resources/shop/SWiftScience

The lesson begins with an introduction to chromatogrpahy, students are shown a diagram to demonstrate this process, they can also take additional notes in their books.

Students will now watch a video on chromatography, whilst watching this video they will need to arrange a set of statements in order to correctly describe the process of chromatography. Students can then self-assess their work once it is complete, using the mark scheme provided on the PowerPoint
presentation.

Next, students will follow the method the have just arranged in their books to carry out their own chromatography practical. This can be completed in groups of 2 or 3, their chromatogram can then be stuck in their books once complete with their conclusion and evaluation completed underneath.

Students will now complete a ‘Quick Check’ task, this is a couple of questions to assess students knowledge of what they have learned so far this lesson, the answers to which are included so students can self-assess their work.

The last part of the lesson focuses on why chromatography is useful, each students will be given an information card which has a description of one use of chromatography. Students will need to walk around the room, sharing information with each other to complete the summary table. Once this task is complete, students can self-assess their work using the mark scheme provided in the PowerPoint.

The plenary task requires students to write a list of key words that they have learned from this lesson.
