What is science?
The intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment.
Science is an organized body of knowledge gathered by observation and experimentation.
Science began in the earliest days of humankind when people observed and recognized temporal patterns in nature: i.e., periodicity in the movements of the sun and moon, regularity in the change of the seasons.
People have been trying to figure out how nature works, in order to be able to control it. Relationships between cloud cover and rain patterns, length of day, change of seasons gives a better chance of not losing the crop, living longer.
Science was practiced by the Chinese in the second millennium B.C. In India, the Middle East, Ancient Egypt, Ancient Greece, and the Americas, humankind's study of the patterns and regularities of nature were recorded and bequeathed to future generations. This legacy of natural philosophy was called science.
Phys – nature, ics – pertaining to, relating to.The first science was physics. It encompassed all types of inquiry into everything.
Matter + Energy Physical Science
Physics is the study of matter and energy.
Today Physics is more often divided into physics and chemistry. We now have biology astronomy, psychology and so forth. Today there is so much scientific information that one person can not master it all. Take doctors for example. There used to be general practitioners. Now there are only specialists.
We believe that the universe obeys a set of rules that we call natural laws. We believe that everything that happens everywhere obeys the same natural laws. Unfortunately, the natural laws are not written down nor are we born knowing them. The primary goal of science is to discover what the natural laws are. Over time, we have found the most reliable way to discover the natural laws is called scientific inquiry.
What inquiry means
Inquiry is learning through questions
Learning by asking questions is called inquiry. An inquiry is like a
crime investigation in that there is a mystery to solve. With a crime,
something illegal happened and the detective must figure out what it
was. Solving the mystery means accurately describing what actually
Deduction One problem always is that the detective did not see what happened.
The detective must deduce what happened in the past from
information collected in the present.
Theories In the process of inquiry, the detective asks lots of questions related to
the mystery. The detective searches for evidence and clues that help
answer the questions. Eventually, the detective comes up with a
theory about what happened that is a description of the crime and
what occured down to the smallest details.
How you know you have learned the truth
At first, the detective’s theory is only one explanation among several
of what might have happened. The detective must have proof that a
theory describes what did happen. To be proven, a theory must pass
three demanding tests. First, it must be supported by significant
evidence. Second, there cannot be even a single piece of evidence that
proves the theory is false. Third, the theory must be unique. If two
theories both fit the facts equally well, you cannot tell which is correct.
When the detective arrives at a theory that passes all three tests, he
or she believes they have learned from their inquiry what happened.
The tools of a scientist, like a microscope, telescope or space probe, help the scientist to "amplify" one or more of the five senses. After gathering information about the natural world a scientist arranges or classifies that information in an organized way. Organizing information helps the scientist to compare observations. An experiment is a carefully controlled comparison of observations.
