How have microscopes developed over time?
Keywords:
  • Microscope : an optical instrument used for viewing very small objects, such as mineral samples or animal or plant cells, typically magnified several hundred times. (1)
  • Electron microscope : a microscope with high magnification and resolution, employing electron beams in place of light and using electron lenses. (1)
  • Resolution : the smallest interval measurable by a scientific instrument. (1)
  • Magnification : the action of visibly enlarging an image. (1)

Students should be able to understand how microscopy techniques have developed over time How has microscopy developedi over time?
This means that electron microscopes can be used to study cells in much finer detail. This has enabled biologists to see and understand many more sub-cellular structures. What impact has the development of the electron microscope had on our knowledge of cells?
Students should be able to explain how electron microscopy has increased understanding of sub-cellular structures. Limited to the differences in magnification and resolution. How has electron microscopy been able to increase our understanding of sub-cellular structures?

View images created by an electron microscope compared to a light microscope. Students to independently come up with the differences between microscope imaging.
An electron microscope has much higher magnification and resolving power than a light microscope. Why is an electron microscope better than a light microscope?

EW - Evaluate an electron microscope against a light microscope.
