Briefly discuss interpretations of your observations and results. Include in your discussion, any conclusions drawn from the results and any sources of error in the experiment

Given the question posted is missing some information and a clear topic, here are a few guidelines and an example to answer your question.

In a written piece (two or three paragraphs most likely to form a discussion) you need a topic sentence, supporting sentences and a concluding sentence to form a well developed paragraph.

For your question, a brief discussion could be described in three paragraphs by discussing it as follows:

1. Interpretations of observations

Ask yourself the questions: What have you observed? Are there any irregularities that you need to note from the experiment versus what should happen theoretically?

2. Interpretations of results

Ask yourself the questions: What results have you observed? Are the results what you initially expected would happen?

3. Conclusions drawn from results

Ask yourseld the questions: What can you deduce from the experiment? What do the observations you have observe mean and how do they inform or differ from the experiment? What can you deduce from the results? What does the results of the experiment relate in theoretical measures?

In each paragraph discuss your own interpretations of the experiment in describing your observations first, then describing your interpretations of the results and lastly discuss your conclusions you have come up with as a result of your interpretations.

Explanation:

In constructing a paragraph for each point you wish to discuss in your answer please note the following for paragraph structure:

Topic Sentence: Introduces the idea or point of discussion for the paragraph

Supporting Sentences: Elaborate and provide more information on your point of discussion in the paragraph.

Concluding Sentence: Relates directly to your topic sentence and ends off your point of view within the topic of discussion.
