Fill out this form for a free study resource: https://forms.gle/tKr66ESYbQFD9qiYA Pearson Edexcel A-Level Biology International — Core Practical 5 In this video, we cover Pearson Edexcel International A-Level Biology Core Practical 5, focusing on microscopy, biological drawings, measurement, and scale. Core Practical 5 objectives (i)Use a light microscope to make observations and produce accurate, labelled drawings of suitable animal cells. (ii)Use a graticule with a microscope to make measurements and understand the concept of scale. In this practical, you will learn how to: -Prepare and observe animal cells using a light microscope -Focus and use the microscope correctly -Produce clear, accurate and appropriately labelled biological drawings -Use a stage micrometer and eyepiece graticule -Calibrate a graticule at different magnifications -Measure structures within cells -Calculate actual size from microscope measurements -Understand and apply magnification, image size and actual size -Convert between units such as mm, µm and nm Avoid common errors when taking microscopic measurements This video is designed to support students studying Pearson Edexcel International A-Level Biology and preparing for practical questions and examinations.
