Gerry and lena work in a modern physics laboratory and study nanotechnology, which is a new type of technology that allows control over individual particles as small as molecules or atoms. even though they work with new technology, they still follow the scientific method, so their experiments attempt to find relationships between independent and dependent variables. for each experiment involving nanotechnology, gerry and lena will test a(n)

For each experiment involving nanotechnology, Gerry and Lena will test AN HYPOTHESIS.
In scientific study, an hypothesis refers to a scientific guess or prediction, which a scientist set out to test in order to confirm if it is right or wrong. An hypothesis usually give a proposed explanation to an observed phenomenon. An appropriate experiment is then set up to examine if the hypothesis is correct. Every scientific experiment starts with an hypothesis.
