Edited resource August 2020.

This lesson plan/presentation provides you with a high quality lesson that includes all the necessary activities for the following learning objectives:

1. Explain the principles of magnification and resolution - engaging starter video on the orders of magnitude, where pupils write down as many of the units of measurement as they can - answers provided in the presentation. Pupils then copy and complete a table where they familiarise themselves with units and conversions. Finally there is a magnification worksheet (Magnification sheet.pdf) and answers are provided in the presentation.

2. Describe what cell fractionation is - pupils complete a reading (AQA A level textbook p.59) and summarising task, sharing their summaries with the rest of the class. There are further questions (p.60) however these could be substituted with your own questions if you are using a different textbook and an extension activity.

3. Explain how ultracentrifugation works - pupils are given an information sheet/worksheet (hidden slide - just print!) on the process of ultracentrifugation. They use the options given in the powerpoint to label the diagram. Answers provided in the presentation.
