Browning Apple: Experimental Conclusion

By Janice VanCleave

An experimental conclusion is a summary of the investigation.

The photo of the girls raking leaves, is much like an experimental conclusion. Both processes involve collecting materials from different places and putting them in one place. Unlike the pile of leaves, which has no particular organization, an experimental conclusion is organized.

The conclusion should state the hypothesis for the science problem being investigated, and state whether the results of the experiment supported the hypothesis or not. If the results did not support your hypothesis, say so, and then add information about why you think this  happened.

Conclusion Form

My hypothesis for this investigation was:_______________________

The results of the experiment  (DID, DID NOT) support my hypothesis.

Brief description of the data that you based your conclusion on.

For Example:

For the following question and hypothesis, an example conclusion is outline below.

Questions: What effect does the type of citric fruit covering apple slices have on their browning ?

Hypothesis: Since all citric fruits contain citric acid, any kind of citric fruit covering apple slices will prevent the slices from browning.

Results:

Apple slices submerged in canned citric juice had no visible evidence of browning. Control #1 ( apple slices submerged in water)  and Control #2 (apple slices exposed to air) both had an equal degree of browning. NOTE: THESE RESULTS MAY OR MAY NOT BE CORRECT. YOU WILL HAVE TO INVESTIGATE FOR YOURSELF.

Conclusion:

My hypothesis for this investigation is, “Since all citric fruits contain citric acid, any kind of citric fruit covering apple slices will prevent the slices from browning.” The results of the experiment did support this  hypothesis.

All apple slices that were submerged in canned citric juices showed no signs of browning. To confirm that it was not just being submerged in a liquid, apple slices were summered in distill water. This was one of the two controls, it was labeled Control #1. The second control were apple slices exposed to air. The two control had equal amounts of browning.

Further Investigations–

Often the results of an experiment will bring up questions that lead to further investigations. For examples of further investigation ideas for the “Browning Apple Investigation” different kinds of edible acids could be used, such a vinegar. Does the concentration of the acid affect the results?
