Amanda holds a Masters in Science from Tufts Medical School in Cellular and Molecular Physiology. Does such evidence prove that your hypothesis is true? Finally, the scientist should understand all of the errors due to measurement, bias and uncontrollable variables that can affect the experiment. This is because you can never examine all of the possible evidence, and someday evidence might be found that disproves the hypothesis. Adopted a LibreTexts for your class? Plus, get practice tests, quizzes, and personalized coaching to help you I asked the young scientist at the science fair if he had any graphs of the data. Was there a kid there that really wanted to conduct a scientific investigation? He had also added in a curve (the green dotted line) to approximate the points (good thinking!). Science will never be "finished." This isolates the independent variable's effects on the experiment and can help rule out alternative explanations of the experimental results. I went to the school to do my judging duty and there were the usual projects: Alaina had a volcano that erupted a vinegar and baking soda mixture; Phillip displayed a three-dimensional mobile of the solar system; and Mariah discussed a potato in a jar of water with a plant growing out of it. Experiments are fraught with uncontrollable variables, bias, measurement error and other unintended consequences, so it's important to understand all these things and take them into account as much as possible. A scientific investigation typically begins with observations. Get the unbiased info you need to find the right school.
