Formal observations are a type of brainstorming that can help you find an idea and form a hypothesis. Observe your subject and record everything about it. The scientific method is a process for experimentation that is used to explore observations and answer questions. The first step of the scientific method involves making an observation about something that interests you. When you design an experiment, you are controlling and measuring variables. If you want to find evidence for an answer or an answer itself then you construct a hypothesis and test that hypothesis in an experiment. She has taught science courses at the high school, college, and graduate levels. Include colors, timing, sounds, temperatures, changes, behavior, and anything that strikes you as interesting or significant. Whether you are doing a science fair project, a classroom science activity, independent research, or any other hands-on science inquiry understanding the steps of the scientific method will help you focus your scientific question and work through your observations and data to answer the question as well as possible. It is important for your experiment to be a fair test. State both your hypothesis and the resulting prediction you will be testing. But even when modified, the goal remains the same: to discover cause and effect relationships by asking questions, carefully gathering and examining the evidence, and seeing if all the available information can be combined in to a logical answer. In fact, there are probably as many versions of the scientific method as there are scientists! What Are the Elements of a Good Hypothesis? What Is an Experiment? It is a … The key difference between the scientific method and other ways of acquiring knowledge are forming a hypothesis and then testing it with an experiment. When printing this document, you may NOT modify it in any way. It is an attempt to answer your question with an explanation that can be tested.

Even though we show the scientific method as a series of steps, keep in mind that new information or thinking might cause a scientist to back up and repeat steps at any point during the process. You conduct a fair test by making sure that you change only one factor at a time while keeping all other conditions the same. Scientists are curious by nature. When direct experimentation is not possible, scientists modify the scientific method. For example, scientists studying how stars change as they age or how dinosaurs digested their food cannot fast-forward a star's life by a million years or run medical exams on feeding dinosaurs to test their hypotheses.

The scientific method is a systematic way of learning about the world around us and answering questions.
