  1. Experimental Conclusions Your conclusion summarizes how your results support or contradict your original hypothesis. You need 4 elements for a complete conclusion • What Happened: Summarize your science fair project results in a few sentences (what happened) • Acc/Rej. Hyp: Restate your hypothesis and reject or accept your hypothesis – give a reason! • Explanation: Explain why you think you got your conclusions (you may need to do some research to answer this) Include any changes you would make if you were to do this again. • Future Experiment: What is a future experiment you could do based on your conclusions (needs to relate to the original experiment)

  2. Sample conclusions What Happened: According to my experiments, the Energizer maintained its voltage (dependent variable) for approximately a 3% longer period of time (independent variable) than Duracell in a low current drain device. For a medium drain device, the Energizer maintained its voltage for approximately 10% longer than Duracell. For a high drain device, the Energizer maintained its voltage for approximately 29% longer than Duracell. Reject/Accept Hyp: My hypothesis was that Energizer would last the longest in all of the devices tested. My hypothesis was correct based on my data. Explanation about why you got your conclusions: I think the tests I did went smoothly and I had no problems, except for the fact that the batteries recover some of their voltage if they are not running in something. Therefore, I had to take the measurements quickly. Future Experiment: An interesting future study might involve testing the batteries at different temperatures to simulate actual usage in very cold or very hot conditions.

  3. Your Hypothesis is False • If the results of your science experiment or research did not support your hypothesis, DO NOT change or manipulate your results to fit your original hypothesis, simply explain why things did not go as expected. Explain what did not match. Professional scientists commonly find that results do not support their hypothesis, and they use those unexpected results as the first step in constructing a new hypothesis. In your conclusion describe what you think should happen next.
