PowerPoint presentation on microscopy - using light microscopes and comparing light and electron microscopes for AQA GCSE Biology.
Full lesson using the learning loop format.
Learning Objectives:
Prepare slides of plant and animal cells and describe the procedure.
Correctly use a microscope to observe cells under different magnifications.
Describe the differences in magnification and resolution of light and electron microscopes.
Explain how electron microscopy has increased understanding of organelles.
Calculate the magnification of a light microscope.
Carry out calculations using the formula: real size = image size/magnification
Rearrange the equation to calculate image size or magnification.
Convert values for the units: cm, mm, µm and nm.
