Scientific Method and Inquiry Process

Ask a question = Formulating a testable question based on observations Do research = Conducting investigations to learn about the topic Form a hypothesis = Creating an educated guess about the expected outcome Perform an experiment = Designing and conducting an investigation to test the hypothesis

Scientific knowledge = Improving as new information is learned Engineering design = Application of scientific knowledge to solve problems or create new things Experiment = Process used by scientists to answer questions about the world Data collection = Using tools to collect information that helps answer scientific questions

Observations = Basis for formulating testable questions Variable = Factor that is changed to see its effect on another factor Trials = Repetitions of an experiment to ensure reliability Patterns = Basis for creating educated guesses (hypotheses)

<p>Independent variable = The factor that is changed by the experimenter Dependent variable = The factor that changes because of the independent variable Constants = Other factors that can affect the data and must be kept constant Variables = Factors in the experiment that change and affect the data</p> Signup and view all the answers

<p>Qualitative data = Observable through the senses, like color, texture, and smell Quantitative data = Measurable, like length, time, or number of people Tables and graphs = Commonly used to organize and display data Patterns in data = Suggest relationships and comparisons</p> Signup and view all the answers

<p>Analyzing data = Organizing and interpreting the results of an experiment Drawing conclusions = Using data to form conclusions and support arguments Sharing results = Communicating findings with others and creating models to describe findings Hypothesizing = Making predictions about how the independent variable will affect the dependent variable</p> Signup and view all the answers

<p>Scientists = Organize and analyze data to determine answers, share results and conclusions Engineers = Use scientific knowledge to develop objects, tools, processes, and systems, test designs, and improve them Experimenter = Changes the independent variable and keeps constants in an experiment Data analysts = Collect and analyze qualitative or quantitative data, and look for patterns and relationships</p> Signup and view all the answers

<p>Independent variable = Variable that is changed in an experiment to see its effect on another variable. Dependent variable = Variable that is observed and measured; its value changes based on the independent variable. Controlled variable = Variable that remains constant and is not changed during an experiment. Experimental variable = Variable that is manipulated or changed by the experimenter.</p> Signup and view all the answers
