Ahmed and Badr successfully addressed the posed question, yet there are diverse approaches to tackling scientific inquiries or resolving problems. Scientists invest considerable efforts in problem-solving, and though each problem demands a unique investigative strategy, there are shared steps across all scientific investigations.


Problem Identification:

Once a problem is identified, scientists prioritize a clear understanding before attempting a solution. Occasionally, multiple problems necessitate different solutions. For example, precise identification of a disease is essential before discovering its source.


How can the problem be solved?

Scientists utilize distinct methods to address problems and answer scientific questions, categorized into two primary types: Descriptive Research and Experimental Research. Descriptive research addresses questions through observation, exemplified in Ahmed and Badr's study on cholera and colonic bacteria. Conversely, experimental research tests hypotheses through organized and sequential steps, following scientific methods.


Descriptive Research:

Certain scientific problems can be addressed or questions answered through descriptive research, often reliant on observations. Descriptive research proves valuable in investigations where experiments are challenging. For instance, British physician John Snow employed descriptive research to trace the source of a cholera outbreak.


Research Objective:

The research objective pertains to what one aims to discover or the question one seeks to answer. Ahmed and Badr sought to discover the tracing methods for the cholera outbreak and E. coli bacteria, mirroring Dr. John Snow's objective to identify the source of the cholera outbreak in London.


Designing the Research:

Scientists must consider critical questions when designing descriptive research, such as how the investigation will be conducted, the steps to be followed, and how data will be recorded or analyzed. Safety precautions are integral, necessitating thorough reviews before commencing any investigation.



Maintaining objectivity is crucial in good research, particularly when scientists anticipate certain results. Effective research avoids bias, with precautions like converting all data into numerical measurements and using random samples contributing to objectivity.


Equipment, Materials, and Models:

Choosing appropriate equipment and materials is vital for executing and analyzing scientific investigations. Modern scientific devices, including balances, microscopes, and computers, enhance data accuracy and analysis.


Data Collection:

Properly organizing and collecting data facilitates interpretation and analysis. Well-designed data tables aid in visually representing results, contributing to better understanding.


Data Analysis:

Understanding the meaning of results is essential after completing the investigation. Carefully reviewing recorded observations and measurements enables accurate data analysis, with graphs and charts serving as valuable tools for visual representation.



Solving scientific problems demands continuous effort and a precise methodology. Clear problem identification and research objectives are crucial initial steps. Whether employing descriptive or experimental research, maintaining objectivity, and careful data collection and analysis are vital for successful investigations. Tables and charts play a significant role in visually representing and comprehending results.
