The burning up of candles is purely dependent on the amount of Oxygen confined in the jar. Therefore, increasing the number of candles causes a proportional increase in the rate of consumption of Oxygen. This causes the candles to go off in the shortest time possible. This is explained by the linear graph shown below. The experiment demonstrates that when candles are more than one, they tend to compete for the same amount of Oxygen available in the jar as opposed to the case where there is only one candle, in which case the available Oxygen is only used by the one candle.

EVALUATION OF THE STUDY.
Evaluation is a way to determine the merits of a study, its significance, and its worth by use of set criteria. It normally helps a researcher to ascertain the number of achievements according to the purpose of the study (Hodgkin, 2002). Its foremost purpose is to facilitate reflection and help in the determination of a change in the future. For this study summative, the evaluation would be the best evaluation process for this study. This is because the summative evaluation is always conducted at the end of a study, and it is used to give out information on the effectiveness and long-term effect of a study (Driver, 1999). To have an assessment of the efficacy of the study, I shall have to follow the following criteria. To start with, I would determine whether the objectives of the study would have been achieved. I shall develop the weaknesses and the strengths, policy, and theory of this study. I would then practice the implications of the study. Next, I would determine whether the ethical committee was approved and whether all the ethical considerations would have been achieved. I shall also establish whether the groups that were used were comparable, whether the confounding factors were well managed, and determine whether the outcomes criteria gave out the required measurements. I shall as well determine whether the follow-up period was sufficient to make the desired effects. If all this is put under consideration, then certainly I would be able to assess the degree to which this study was a success. However, the most notable shortcoming of this experiment was that the sample size used was small. In the future, the sample size should be expanded to about seven candles. This would be appropriate since it would help make an inference that is the most reliable.
Conclusion.
From the results obtained, it is certainly true as far as the hypothesis of this experiment is concerned that when one lights one, two, or three candles in a closed jar, the flame goes out for all three cases and that the one-candle case would be the first to go off, followed by two candles and finally the three candles. This clearly illustrates that the rate of consumption of Oxygen is directly proportional to the number of candles. This is because the burning up of candles is purely dependent on the amount of Oxygen confined in the jar. Therefore, increasing the number of candles causes a proportional increase in the rate of consumption of Oxygen. This causes the candles to go off in the shortest time possible. From this experiment, it is also clear that the burning up of the candle is depended on the amount of Oxygen. Hence the ward equation for the burning of the candle is true.
