Do You Ponder Why Something Happened ?
Science is the study of the behavior and nature of things and knowledge that we can obtain about them.Simply it a tool that use to understand the natural world. What I mentioned as natural in here is all that we can observe with use of our senses. Science is concerned with testable knowledge of the universe's physical events. The objective of science is to figure out how the universe works. Biology is concerned with the study of living things. Biology is a scientific branch which concerned with the study of living creatures. Chemistry is a branch of science concerned with the study of atoms and molecules. Natural sciences and social and behavioral sciences are the two main fields of science. Scientists use a method called "scientific enquiry" to learn more and to gain knowledge about nature and physical events.
Scientific Inquiry
Science can be defined as learning or understanding new things or understanding or exploring about things.Inquiry means asking about information or investigating something to get for details.Therefore we can say “Scientific Inquiry” as a method which use evidences from observations and investigations to make logical explanations and to answer questions.Normaly scientific inquiry has two basic functions.First it provides a description of how scientific inquiry is conducted in practice and secondly gives and explanation of why scientific inquiry is successful in arriving at genuine knowledge at the end of its process.When students engage in scientific inquiry, it is an important part of science instruction that helps to students to develop scientific literacy. And also it provide students opportunity to practice important science process skills in addition to critical thinking and problem solving skills.
Scientific Method
Scientific method is a way of discovering the knowledge about the natural world with the use of making hypothesis and testing them.And making peer reviewed theories which explain known data. When conducting research, scientists use the scientific method to gather measurable, empirical proof in experiment associated with a hypothesis and the results reaching to support or contradict a theory.
Steps of Scientific Method
Basically we can find five basic steps in scientific method. And one more step to make the feedback. This scientific method used in every sciences like chemistry, physics, biology, etc.Scientists in those fields ask questions and perform tests. However, they use identical core approach to search out answers that are logical and supported by proof. Here are the steps of scientific method ;
1. Observation
2. Ask question
3. Form Hypothesis
4. Test with experiment
5. Analys data
6. Make conclusion
Hypothesis testing
Statistical inference is the process of drawing inferences about a population based on data from a sample of that population. Hypothesis testing is a way for evaluating the strength of evidence from a sample and providing a framework for making population-related decisions. It also gives a method for determining how reliably observed findings may be extrapolated. A hypothesis is a potential answer to the question, one that can somehow be tested. Your experiment determines whether or not your prediction was correct, and hence whether or not your hypothesis is supported. It's critical that your experiment be a fair test. A fair test is one in which just one component is changed at a time while all other variables remain constant. You should also repeat your tests numerous times to ensure that the first results aren't a fluke.
