A detailed and engaging lesson presentation (38 slides) and accompanying worksheet that looks at the structures found in prokaryotic cells and ensures that students recognise the differences (and similarities) between these cells and eukaryotic cells. A series of quick competitions are used throughout the lesson to aid motivation and a format of a Venn diagram is used for the students to show the information. The lesson begins by focusing on the nucleus and how its absence in prokaryotic cells is a key difference. Moving forwards, students will be challenged to use previous knowledge of animal and plant cells to name structures that are found in both and only in eukaryotic cells. There is a real focus throughout on key terminology and progress checks are regular so that students can check their understanding.
