Each step of the process must be handled with care. imaginable degree, area of Why or why not? Investigation. I asked the young scientist at the science fair if he had any graphs of the data. However, investigations in … Do some background research on the question so that you can create a hypothesis, or an educated guess about what will happen. Science is the process of gathering, comparing, and evaluating proposed models against observables. Intrigued, I asked him a number of questions. … For example, in our plant example above a hypothesis might look like, "If we add fertilizer then the plants will grow taller because fertilizer contains limiting growth factors that plants need.". The data in a science fair project is the information in the graphs on your science fair projects. What characteristics must a hypothesis have to be useful in science? "The students of Mrs. Doe's 10th grade science class have been studying the skeletal system. 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. It can be expressed in the form: If A occurs, then B will happen. This is a sort of educated guess about what you expect. A method is planned so the prediction can be tested.

What reason might there be for this observation? It's much easier to analyze data and compare it to an existing theory than to try to develop a theory from scratch. Scientific investigation, when applied correctly, will continue to be the main way that scientists build better models and explanations for phenomena in the world around us. Define investigation. If other researchers get the same results as yours, they add support to the hypothesis. Evidence is any type of data that may either agree or disagree with a prediction, so it may either support or disprove a hypothesis. In our plant experiment, the table might look like this: Next, it's time to analyze your data. A workplace investigation is a process that researches an unclear situation involving employees. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Observations often lead to questions. So the part of gravity that is affecting my car changes with the angle, but it changes less at the higher angles. These methods include (in no particular order) fair testing, identifying and classifying, modelling, pattern seeking, and researching. How did the Scientific Revolution change the way scientists worked?
