Solving a biological problems
Solving a biological problems
Science is the systemized knowledge derived from observations and experiments.These experiments are carried out to determine the principles about how nature operates.Scientists like chemist, biologists and physicists use the same scientific method to make and test new theories.
Biological method Definition
Question about living thing have provided problems that man has investigated to aid this own survival and to satisfy his desire to know.The scientific method in which biological problems are solved, is termed as biological method.It comprises the steps a biologist adopts in order to solve biological problems.
Biological method has played an important part in scientific research for almost 500 years.From Galileos experiment to current research, the biological method has contributed to the advancements in medicine, ecology, technology etc.Biological method also ensures the quality of data for public use.
Man has always been biologist.He had to be a biologist in order to to live.Early in history, he was a hunter of animals and gatherer of fruits, seeds roots etc.The more he knew about animals and their habitat, the more successful hunter he was.The more he knew about plants , the better he distinguished between edible and non edible plants.
Biological problems , Hypothesis, Deductions and experiments
In Biology new things are being discovered and long held theories are being modifies or replaced with better ones as more data / knowledge is accumulated.This happens when biological recongnize some biological problem and go for its solution.In solving biological problems, biologist takes following steps.
Recongnization of biological problems.
Observations.
Hypothesis formulation
Deductions
Experimentations
Summarization of results
1.Reporting of results
Recongnization of the biological problems
Biologists go for adopting biological method when they encounter some biological problem.A biological problem is a question related to living organisms that is either asked by some one or comes in biologists mind by himself.
2.Observations
As the first step in solving a biological problems biologists recalls his or her previous observations or makes new ones.Observations are made with five senses of vision, hearing , taste , touch .Observations may be both qualitative or quantitative.Quantitative observations are considered more accurate than qualitative ones because the former are invariable and measurable and can be recorded in terms of numbers.Examples of Qualitative and Quantitative observations are given below.
( Darwin not only observed and took notes during his voyage, but he also read the works of others naturalists to form his theory of evolution. )
Qualitative observations ; The freezing point of water is colder than the boiling point
Quantitative observations; The freezing point of water is 0 C and the boiling point is 100 C.
3.Formulation of hypotheses
Observations do not become scientific observations until they are organized and related to a question.Biologist organizes his or her and others observations into data from and constructs a statement that may prove to be the answer of the biological problem under study.This tentative explanation of observations is called a hypothesis.
It should be a general statement.
It should be a tentative idea.
It should agree with available observations.
It should be a kept as simple as possible.
It should be testable and potentially falsifiable.
A great deal of careful and creative thinking is necessary for the formulation of a hypothesis.Biologists use reasoning to formulate a hypothesis.
4.Deductions
Biologisit draws deductions from hypotheses.Deductions are the logical consequences from hypotheses.For this purpose, a hypotheses is taken as true and expected results are drawn from it.
Generally in biological method, if a particular hypothesis is true then one should expect a certain result.This involves the use of if then logic.
5.Experimentation
The most basic step of biological method is experimentation.Biological performs experiments to see if hypothesis are true or not.The deductions which are drawn from hypotheses, are subjected to rigorous testing.Through experimentation biologist learns which hypothesis is correct.
6.Summarization of results
Biologist gathers actual , quantitative data from experiments.Data for each of the groups are then averaged and compared statistically.To draw conclusions, biologist also uses statistical analysis.
7.Reporting the results
Biologists publish their finding in scientific journals and books, in talk at national and international meetings and in seminars at colleges and universities.Publishing of results is an essential part of scientific method.It allows other people to verify the results or apply the knowledge to solve other problems.
