Scientific Investigation
Research
The first action of any investigation is to research on the topic. There are several reasons for making an investigation. For instance, an investigator may wish to continue with a previous investigation he or she had conducted, or something he or she has noticed in their daily life. The investigator can get more information on the research topic from the internet, magazine, books, or ask someone with knowledge on the subject or find out what other people did concerning the same experiment.
Problem
At this stage, the investigator needs to narrow down his or her observation to a simple question or questions that can be tested and answered. The question formed would then lead to the hypothesis or speculation of the investigation.
Hypothesis
The hypothesis is a statement that the investigator tests and then proves it either true or false. It is stated before starting the experiment, and the investigator should give an explanation why he or she chose it. It should be written down since it forms the basis of the experiment. However, it should not be changed even if the results turn out to be false. Science is not concerned about right or wrong, but coming up with an answer.
Experiment (Method)
It involves the different steps taken to test the hypothesis. It includes all the procedures to be used in the experiment while also describing measurements or observation made. In a proper investigation, all the control variables should be kept the same except for the independent variable that should be changed in the experiment.

The results that would change because of the independent (manipulated) variable are known as responding variables. Experiments should be carried out in batches and the test repeated under the same condition to get accurate results. It will minimize biases. Further, photographs can be taken to help show the methods used in the experiment.
Results
In this section, the investigator obtains the results and allows the entire world to know what he or she found out from the experiment. It is not necessary for the person to show all the calculations. Also, it is important to mention the methods used. For example, the formulas used to calculate the mean, mode, standard deviation, and so on. Tables, pie charts, and graphs can also be used to present the findings.
Discussion
At the completion of the experiment, the investigator should make a detailed observation and analyze the findings of the experiment. At this point, the investigator should answer the following questions. Do the findings support the hypothesis? Does the investigation require more research to be carried out? Besides, he or she can point out errors in the experiment.
Conclusion
The conclusion answers the investigator’s hypothesis as briefly as possible. It is because the answers have already been explained in the discussion section in detail. The investigator should also leave some questions for other future scientists to expand on as they carry out their project research.
Report Writing
It involves writing down the report.
