microscopes

microscopes


why we use them

we use microscopes so that we can see really small things .............

like cells in animals or plants

we also use microscopes to look at things in greater detail maybe so we can classify it more easily

how microscopes work

microscopes use a series of lenses and zooming in and out to help you see objects that are to small for us to see.

who invented the microscope

The first microscope was made around 1595 in Middelburg, Holland. Three different eyeglass makers have been given credit for the invention: Hans Lippershey (who also developed the first real telescope); Hans Janssen; and his son, Zacharias. The coining of the name "microscope" has been credited to Giovanni Faber, who gave that name to Galileo Galilei's compound microscope in 1625. (Galileo had called it the "occhiolino" or "little eye".)
