Possibly the most important and, at the same time, the most neglected phase of the scientific method is the compilation of a complete portfolio. If scientists as a group fail to report their results, then each of us must wake up in a whole new world every day, doomed to repeat the failures of the past or else to waste time and effort in the rediscovery of old knowledge. Your portfolio should include:
Your question.
Your hypothesis, along with your reasoning for why you arrived at that hypothesis.
Your research.
List of variables.
A summary of your observations and results from the experiment.
Statement of support or non-support of the original hypothesis based on the data gathered in your experiment.
Description of any problems or unusual events that occurred during the investigation that might have affected your results.
What changes you would recommend for next time, and what further experiments might need to be done to fully answer the question?
What further questions do you have about the topic? What ideas do you have for studying the topic in the future.
Anything you learned in addition to what you expected to discover.
Acknowledgments. You should always credit those who assisted you including individuals, businesses, and institutions.
References/Bibliography. If this information looks familiar to you, it should.
The report is simply a summary of all your work. That’s why people tend to neglect it -- they are eager to move on to the next problem. Remember, however, it’s the most important part of real-world science!
