AQA GCSE Biology- Microscopy

Designed for the new specification AQA GCSE course but can be modified for other exam boards.

22 slides covering Microscopy:

By the end of the powerpoint students would have covered (includes a required practical):

Students should be able to:

understand how microscopy techniques have developed over time
explain how electron microscopy has increased understanding of sub-cellular structures.

Limited to the differences in magnification and resolution.

An electron microscope has much higher magnification and resolving power than a light microscope. This means that it can be used to study cells in much finer detail. This has enabled biologists to see and understand many more sub-cellular structures.

Students should be able to carry out calculations involving magnification, real size and image size using the formula:
magnification = size of image
size of real object

Students should be able to express answers in standard form if appropriate.

Required practical activity 1: use a light microscope to observe, draw and label a selection of plant and animal cells. A magnification scale must be included.
