In аn effоrt tо use up аll the blueberries in their refrigerаtоr, James decided to double the amount of blueberries in a blueberry loaf recipe. The resulting loaf turned out inedible, with a gummy texture and a sunken center. James suspected that the excess moisture from the additional blueberries caused the loaf to fail. They hypothesized that using the correct amount of blueberries, as specified in the recipe, would yield a better result. The next time they prepared the loaf, James followed the recipe exactly, using the recommended amount of blueberries. This time, the loaf came out delectable, springy, and soft. For this scenario identify the observations, hypothesis, and experiment.
