Correctly writing lab reports will enhance your scientific communication skills. We will use this Circle Lab to model proper techniques for sharing information by focusing on the Conclusion section of a lab report. Your conclusion will have three parts: a restatement of the purpose (which answers the question, "Why did we do this activity?"), a brief description of the results of the activity and what you learned (do not include the procedures), and possible sources of error (be specific, for example, "human error" is too vague). Remember that the conclusion is a narrative that is written in complete sentences.
