Many of the questions about life are being answered through our day to day experiences. But scientists solve their problems by a precise process
called the scientific method. Many discoveries and inventions made are valid because the scientists use the scientific method. The scientific
method is a system of acquiring information and tools about life by developing explanations or solutions to questions followed by continuous
testing.
THE STEPS OF THE SCIENTIFIC METHOD
The scientific method follows a sequence of thought processes and activities:
Observation
Define clearly a specific problem and start with an observation. This process includes reading, use of the senses of sight, smell, hearing, touch, and taste, or use of biological tools like the microscope, pH meter, weighing balance, etc. Careful and confirmed observations become facts. Facts are truths and often called data which result from observations made during evperiment
Formation of Hypothesis
A hypothesis not only explains the facts but also predicts new facts. Testing of
Hypothesis
To check, the hypothesis involves experimentation. Scientists conduct controlled experiments in which all the factors are the same except the one being tested. A variable is the factor that differs among the test group.
Analysis and Conclusion
Analyze the results of the experiments and make conclusions. A theory has been established under the information has been consistent with current scientific laws.
