Okay so I read your part on the discussion... and I added it to my discussion it just seems like I need more my professor said that the discussion part is supposed to repeat everything talked about in the previous sections like the intro,methods ect. It just sounds so incomplete. And would it sound good to put that stuff I told you about how I got the iron cereal solution into the introduction

Yes, you need to describe everything you did in the intro although you may want to give an intro only there and describe it in more detail in the methodology. That material definitely belongs there. As for the discussion, yes, you discus what you did and you discus the results but you don't need (or want) to repeat the intro part and you don't need to repeat the methodology UNLESS something in the methodology would make the results better, more convenient, more precise, etc. One thing I have forgotten until now---How many of these samples did you do? Is the 39% an average of several samples. You need to give the percent of each sample you ran, the average of all the samples you ran, as well as a precision. The precision can be whatever your prof wants. Often it is a percent precision from the mean (especially if you ran only two or three samples) but standard deviation is used as well as several others, especially when more samples are done. Did you have any results you did not show? If so, you can do a t test or some other test to determine if that result can be discarded. That goes in the discussion also.

It seems like you are looking for guidance on how to improve the discussion section of your research paper. The discussion section is an important part where you interpret the results and analyze their implications. Here's an explanation of how you can expand and enhance your discussion:

1. Summarize key findings: Start by summarizing the main findings of your study. Briefly restate the results you obtained in the previous sections, such as the introduction and methods. This provides a context for your discussion and reminds the readers of what you investigated.

2. Interpret your results: Analyze and interpret the significance of the findings. What do the results mean in the context of your research question or hypothesis? Explain any patterns, trends, or relationships that emerged from the data. Use evidence and logical reasoning to support your interpretation.

3. Compare with existing research: Relate your results to previous studies conducted in the same field. Discuss how your findings align with or differ from what other researchers have reported. This demonstrates your understanding of the existing literature and contributes to the broader scientific knowledge.

4. Discuss limitations: Acknowledge any limitations or boundaries of your study. Highlight potential sources of error or bias that might have influenced your results. This displays a critical evaluation of your research and helps the readers understand the scope of your findings.

5. Implications and significance: Discuss the broader implications of your findings. How do they contribute to the understanding of the topic? Explain why your research is relevant and important. Consider any practical applications or future research directions that arise from your study.

As for including the information about how you obtained the iron cereal solution in the introduction, it would be more appropriate to include such details in the methods section. The introduction primarily focuses on providing background information, context, and the research question or objective of the study. The methods section, on the other hand, describes the materials, procedures, and techniques used to conduct the research.

Remember, the discussion section should not simply repeat the content from other sections but rather provide an analysis and interpretation of the results. By following these steps and expanding on each aspect, you can create a comprehensive and engaging discussion section for your research paper.
