Light microscopy: observing and drawing cells
I can use a light microscope to observe and produce scientific drawings of cells.
Lesson details
Key learning points
- A light microscope can be used to observe animal and plant cells.
- The parts of a light microscope and their functions.
- The sequence of steps setting up a light microscope to observe cells, including changing the magnification and focus.
- Observations from a light microscope can be recorded in a labelled scientific line drawing with an indication of scale.
- The magnification and real size of structures observed with a microscope can be calculated.
Common misconception
Cells are inert 'building blocks' like bricks. Microscopes can see structures as small as molecules.
The lesson explores what cells are, including that they are living units, and considers what can and can't be seen using a light microscope.
