In This Video Lecture You Will Learn Basic Concept Of Biological Method

Biology is one of the major sciences. Scientists have acquired biological knowledge through a process known as the scientific method. The steps of the scientific method make up an orderly way of gaining information about the biological world. Sometimes the knowledge gained is useful in solving particular problems; other times it is simply of interest without any practical application at the time.

The scientific method requires a systematic search for information by observation and experimentation. The basic steps of the scientific method are stating a problem based on observations, developing a research question or questions, forming a hypothesis, experimenting to test the hypothesis, collecting information, recording and analyzing data, and forming a conclusion.
Observation
The first step in the scientific method is stating a problem based on observation. In this stage, the scientist recognizes that something has happened and that it occurs repeatedly. Therefore, the scientist formulates a question or states a problem for investigation. The next step in the scientific method is to explore resources that may have information about that question or problem. Here, the scientist conducts a literature review and interacts with other scientists to develop knowledge about the question at hand.
Hypothesis, experimentation, and analysis
Next, a hypothesis is formed, meaning that the scientist proposes a possible solution to the question, realizing that the answer could be incorrect. The scientist tests the hypothesis through experiments that include experimental and control groups. Data from the experiments are collected, recorded, and analyzed.
Conclusion
After analyzing the data, the scientist draws a conclusion. A valid conclusion must be based on the facts observed in the experiments. If the data from repeated experiments support the hypothesis, the scientist publishes the hypothesis and experimental data for other scientists to review and discuss.
Theory and law
Other scientists not only may repeat the experiments but also may carry out additional experiments to challenge the findings. If the hypothesis is tested and confirmed often enough, the scientific community calls the hypothesis a theory. Then numerous additional experiments test the theory using rigorous experimental methods. Repeated challenges to the theory are presented. If the results continue to support the theory and are found to be universally applicable, the theory is elevated to a scientific law. A scientific law is a universal, uniform, or constant fact of nature. Sir Isaac Newton’s law of gravity is an example of a scientific law.

About This Channel.....................

I make these videos cause I love to draw and connect the complexity of science and medicine into art. I'm not saying. I'm 100% correct in all my videos, but I do try to obtain the information from credible sources.
One-stop destination for all biology lectures.
_ students in class 11, 12 or appearing for competitive medical exams ( NMDCAT ) will find it very beneficial
_ The videos are categories under various heading to make the students life simplified
