Browning Apple: Experiment

By

A science fair project experiment must test the accuracy of the hypothesis. For this example science fair project the example question and hypothesis are: Question: 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 […]

A control experiment is the standard for the experiment. This means that the results of the project experiment are compared to the results of the control. Since changes in the project experiment’s independent variable causes changes in the experiment’s dependent variable, then the independent variable is kept constant (unchanging) in the control experiment. Removing the […]
