A magnifying glass (called a hand lens in laboratory contexts) is a convex lens that is used to produce a magnified image of an object. A hand lens can be used to magnify an object to make it easier to see or also to focus light.
to magnify something, and to focus light
To make it easier to see & focus

Two ways that scientist can use the technology is to communicate informationand to quickly record,store , and anylize.

They can use hypothesis and varible answers
When viewing a specimen through a hand lens, you can see in slightly greater detail than your naked eye, but you may not be able to see micro organisms. With a microscope, you can see things in MUCH greater detail, and you can see micro organisms. With a hand lens, you cannot change the power of magnification, while with a microscope, you can change the power of the magnification. With a hand lens, only one lens is used to magnify an object, while a compound microscope uses two lenses (one in objective lens, one in eyepiece). With a hand lens, you can view a specimen from far away, while an objective lens has to be fairly close to a specimen in order to view it clearly. With a hand lens, you can simply move your hand forward, or backward, to focus on an object. With a microscope, a very complex mechanism is used in order to portray some sort of depth while viewing. This is adjusted by using a coarse, and a fine adjustment knob.

by either moving the object understudy to the focal point of the lens or to move the lens until the object is at the focal point.
People hunting for fossils use hand lens and some crime labs do as well.

observing,inferring, are two ways. Find the rest.

ther are only two different ways that scientist does not collect data
