Plan of experiment to investigate the effect of different spring stiffness with the same weight

"The essay was overall quite informative and covered the essentials of what is required in the coursework. I thought the plan was a little weak and could have done with some additional information, such as, what you hope to achieve from the preliminary and results. The preliminary could have also done with some additional conclusions of what you obtained, and what you plan to change for the main experiment. The results and Analysis were fine, although I can't see any of the diagrams, or graphs etc, so it's hard to tell! The evaluation could have done with some more information, such as greater depth in any anomalies in the data, and explanation why this could have happened. For those wanting to achieve top marks, it would have been useful to add what Further experiments you could do to further your knowledge on the subject. The presentation was fine, although I would add more sub headings to really make a point of where everything is, so it's easier for the examiner to mark you and to make sure he/she doesn't miss anything. Overall a solid piece of work, which covered all the essentials needed, but could have had more detail for those extra marks. TSR User:Phobia27"
