Science refers to a system of getting knowledge based on scientific method and also refers to the organized body of knowledge gained through such research.
People who do science are called scientists. Scientists study things by looking at them very carefully, by measuring them, and by doing experiments and tests. Scientists try to explain why things act the way they do, and are the way they are. Scientific method The "scientific method" is the name given to the methods used by scientists to find knowledge.
The main features of the scientific method are:
The scientific method is a "trial and error" method. (Scientists try something to see if it works or not.)
The scientific method depends on data.
The product of the scientific process is something called a "theory".
Most people accept the scientific method as the most reliable way to get knowledge about nature, the universe, and the human body. Other features of science Not everyone agrees about how science works exactly. Some philosophers and scientists say that scientific theories are only accepted as long as they are the best explanation for the data that exists, and when theories no longer explain the data, they are discarded and replaced. Other people say that sometimes scientists will make a theory better rather than discard it, or that they will keep on using the theory hoping that it will be made better eventually.
Science is a way to get knowledge by discarding what is not true.
Scientists must be very careful to make explanations that fit well with what they observe and measure. They compete to provide better explanations. An explanation might be interesting or pleasing, but if it does not agree with what other scientists really see and measure, they will try to find a better explanation.
Before a scientific article is published, other scientists read the article and decide whether the explanations make sense from the data. This is called peer review. After articles are published, other scientists will also check if the same experiments, observations or tests produce the same data again. Peer review and repeating experiments are the only way to be sure the knowledge is correct.
Science makes models of nature, models of our universe, and medicine. There are many different sciences with their own names. However, it is not right to say, "Science says" any one thing. Science is a process, not just the facts and rules believed at one time. Some types of science Biological sciences
