Key Stage 2
Meaning
A picture of a microscope.
A microscope is piece of equipment used to make small objects appear larger.
About Microscopes
- Microscopes can be used to see things too small for our eyes to see.
- Micro means 'small' and scope means 'small'.
Key Stage 3
Meaning
A microscope is piece of equipment used to make small objects appear larger.
About Microscopes
- Microscopes use convex lenses to magnify an image.
- The parts of the microscope are shown in the diagram below:
 |
- Eyepiece Lens - This is the lens that you look down.
- Coarse Focussing Wheel - This moves the stage by a large amount to bring the image into focus (make the image clear and not blurry).
- Fine Focussing Wheel - This moves the stage by a small amount to focus the image carefully (make the image clear and not blurry).
- Objective Lens - This is the lens next to the specimen that magnifies the image.
- Stage - This where the sample is placed.
- Light Source - This can be a lamp or a mirror used to shine light through the specimen.
Preparing Specimens
To see an object clearly with a microscope a specimen must be prepared first.
