There are many devices that make objects appear bigger than their real size.
A magnifying glass is a lens mounted in a frame with a handle. It can make an object to appear up to twenty times bigger.
A light microscope uses a series of lenses in a tube. It allows us to see very tiny things like bacteria and create an image of them up to one thousand times bigger than the real thing.
Some things are so tiny that if we want to see them we have to use a microscope that uses something smaller than visible light. This microscope is called the Scanning Electron Microscope.
