Science is an organized enterprise which builds and directs knowledge in the form of precise testable predictions and explanations about the universe. In a word, it deals with the problem of understanding, testing and manipulating phenomena in a scientific way. A scientist engaged in science is someone who is devoted to the proper conduct of scientific research, who has a clear attitude toward evidence and rigorous methods, and who uses the results of his or her investigations to formulate theories, treat problems, and provide solutions to problems. In other words, a scientist is a specialist in some certain area of science whose work deals with the problem of understanding and using particular laws and principles.
A scientific theory explains the nature and attributes of an object or event through a set of ideas or theories. It can be either physical or mental. A physical theory may be the hypothesis that “X” causes Y in the sense that if X exists, Y will also exist. For instance, if scientists believe that ultraviolet rays from the sun cause wrinkles on the skin, they could assert that “UV light” is the hypothesis.
The major portion of the population in the world is employed in some form of the natural or social sciences. A major part of the world population work in some form of the natural or social sciences. Natural science, as opposed to engineering science, is typically devoted to the study of the natural world around us. The natural scientists seek to understand the relationships among organisms, the earth’s climate, the composition of the soil, and so on. Natural scientists use a wide range of techniques, including field work, to observe the natural world around them and to record its changes.
Scientists use a wide range of techniques to study the natural world. One of the most common techniques is the observational study. In this type of science, the scientist simply observes things happening around him or her. Examples of observational science include watching the stars in the night sky, tracking the movement of the stars across the sky, and tracking the planets through satellites. These scientists are attempting to observe and record new information about the world around them.
Another common practice within the natural world science is experimental or research study. In this type of science, a hypothesis is formed based on observations and new evidence is sought to test this hypothesis. The hypothesis may be tested against opposing theories, or against statistical evidence. Once the hypothesis is either accepted or rejected, the research is halted until further evidence supports or disproves the hypothesis.
If you are considering a science fair project, consider developing a hypothesis, using observations of nature to support it, and then developing your experiment to test your hypothesis. You can do all of these things by taking an active role in your science project. The hypothesis is the starting point of your project, and once you’ve formed one, you need to build on it to develop a proper hypothesis and procedure to test it.
If you are interested in developing a deeper understanding of the natural world, you may want to consider a science project that explores many different scientific practices. For example, did you know that each day millions of birds fly into the air. We don’t often think about how they get there, but all over the world, scientists are gathering data on how these little flappers get to their destinations. Have you ever wondered how they survive the flight? Birds have developed very complex flight systems over the years, and now there are scientists who are using the details of their development to give us a deeper understanding of how living things move through the environment.
When you consider a science fair project that involves observation, you are developing a deeper understanding of what science is truly about. Science is not static. It changes constantly, and it is through the process of observation and experimentation that we learn more about what science is. So make observations of nature, and then formulate a hypothesis, and you’re well on your way to developing a deeper understanding of the natural world around you.
