Microscope
A microscope uses two or more lenses, one after another, to show tiny things such as cells hundreds of times bigger. Light from a lamp shines up through a thin sample on a glass slide, then through the objective lens and the eyepiece. You start with the lowest magnification, bring what you want to see to the middle, then go higher; multiplying the numbers on the two lenses gives how many times bigger the sample looks.
