The work of scientists can be very diverse. Research can take place in the field or in the lab, and methods of analysing results are advancing all the time as modern technology makes new things possible.
For example, we can now date rocks more accurately than we used to be able to. Also, the study of DNA lets us work out relationships between organisms in a new way.
