Explain the dynamic nature of science with examples.

The new Science curriculum has the 'nature of science' right up there at the top. And why? Because it's so important for people to learn, not just science facts and concepts, but also about what science is: how it's done, the tools and methods scientists use, how they communicate, its history, & how science is a part of everyday life.

Science is dynamic in nature - it's not a fixed set of facts & doesn't simply represent the 'truth' about the natural world, but changes through time as new data are collected. Darwin was alive at a time when scientists were redefining a whole range of concepts ('species', for one). Scientists are constantly coming up with new questions, new interpretations, and new opinions. And because of this, it is eventually self-correcting.

A good (non-evolutionary) example here is the discovery that most stomach ulcers are caused by infection with the bacterium Helicobacter pylori. When this idea was first proposed, biologists laughed at it. But the scientists concerned persisted and demonstrated - by infecting themselves, among other things - that the infection/ulcer link existed. The weight of evidence convinced the scientific community - and the scientists who made the discovery received a Nobel Prize.

 Biology is a quest towards understanding, one that is ever changing and one that has roots not only in the phenomena that we observe, but in the human world that shapes our concerns and questions. And still biology is the vast concept of learning and understanding concept in the field of science.
