Using a Microscope — Interactive Lesson (Ages 11–14)

Cells are far too small to see with your eyes alone. Teach pupils to use a light microscope properly. This 18-slide interactive lesson on using a microscope takes pupils from first ideas to exam-style explanations, with 10 self-marking activities and nothing to prepare beforehand.

Teaching Using a Microscope in KS3 Science

Pupils name the parts of a light microscope and their jobs, calculate total magnification from the eyepiece and objective lenses, and follow the steps to prepare a stained slide of onion or cheek cells. They learn to focus safely, starting on the lowest power and using only the fine focus at high power, and compare what can be seen in plant and animal cells.

What Pupils Will Learn

• Name the parts of a light microscope and what they do.
• Calculate total magnification.
• Prepare a slide of onion or cheek cells.
• Focus a microscope safely and correctly.
