In this experiment‚ the question being asked was: “What is the water quality of the U-High stream based on the water invertebrates found?” The purpose of this experiment was to determine the water quality of the U-High creek. The data was obtained by collecting soil‚ algae‚ and water from the U-High creek and identifying the number and types of invertebrates that were found from the samples. The prediction made was that the U-High creek’s water quality was poor based on the first observations of
