Observing cells with a light microscope
I can use a light microscope to observe cells.
Lesson details
Key learning points
- All organisms are made up of living building blocks called cells.
- Cells are usually too small to see with the unaided eye.
- The cells that make up tissue on a slide can be observed using a light microscope.
- Changing the magnification and focus of a light microscope enables cell structures to be observed.
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.
