CIE 1.1 The Microscope in Cell Studies

This lesson can be taught over several sessions. Students start by revisiting how to prepare slides for viewing under the miscroscope, and how to draw observations to A Level standard. YouTube videos and practical tasks are included. The PPT includes micrographs of cells for students calculate magnification and actual size. Later, students are taught how to use a graticule and stage micrograph when calibrating a microscope with practise calculations, working out sizes of specimens. The lesson concludes with a research task on the differences between light, and electron microscopes. The PPT is interspaced with exam questions to assess progress. Also included is a practical booklet that students can use to independently conduct the miscroscope practical, if required.
