Investigation is the heart of
It is how scientists do research
Scientific
produce evidence that helps answer questions and solve
problems. If the evidence cannot provide answers or solutions, it may still be
useful. It may lead to new questions or problems for investigation. As more
knowledge is discovered, science advances incurred.
Scientists investigate the world in many ways. In different fields of science
may use different methods and be guided by different theories and
However, most scientists, including physical scientists, usuall
