Understanding the Scientific Method

Ask a question = Formulating a testable question based on observations Do research = Conducting research to gain knowledge about the topic being investigated Form a hypothesis = Creating an educated guess about what will happen based on observed patterns Perform an experiment = Designing and conducting an investigation to test the hypothesis

Hypothesis = An educated guess about what will happen based on observed patterns Variable = A factor that is changed in an experiment to observe its effect on another factor Data = Information collected during an experiment to help answer a scientific question Trial = A single instance of an experiment or investigation

Observation = Basis for formulating testable questions in the scientific method Research = Gathering knowledge about the topic being investigated Data collection = Using tools to collect information that answers scientific questions Experiment design = Planning and conducting investigations to test hypotheses

<p>Learning new information = Process that leads to improvement in scientific knowledge Application of knowledge = Using acquired knowledge to solve problems or create new things through engineering design Conducting experiments = Investigative process that contributes to enhancing scientific knowledge Engineering design = Utilizing scientific knowledge to create something new or solve a problem</p> Signup and view all the answers

<p>Changing a variable = Altering a factor in an experiment to observe its impact on another factor Using tools for data collection = Employing instruments to gather information that aids in answering scientific questions Multiple trials = Repeating an experiment multiple times to ensure reliability and consistency of results Forming cause-and-effect relationships = Establishing connections between changing a factor and observing its outcomes in an experiment</p> Signup and view all the answers

<p>Modeling and explaining the world = Utilizing skills and processes to understand and interpret phenomena through scientific means Improving scientific knowledge = Enhancing understanding through learning new information and conducting experiments Problem-solving and creation = Applying scientific knowledge to address issues and innovate through engineering design Conducting experiments and investigations = Utilizing the scientific method to explore and answer questions about the world</p> Signup and view all the answers

<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 Qualitative data = Observable through the senses, like color, texture, and smell</p> Signup and view all the answers

<p>Analyze the data = Organize and analyze the data to determine answers to testable questions Draw a conclusion = Use the data to form conclusions and support arguments about the studied problem Share the results = Share the results and conclusions with others, and create models to describe findings Collecting and analyzing data = Collect qualitative or quantitative data during experiments and analyze it</p> Signup and view all the answers

<p>Scientists = Organize and analyze data, draw conclusions, share results, and create models to describe findings Engineers = Use scientific knowledge to solve problems by developing objects, tools, processes, and systems Experimenter = Change the independent variable and keep constants constant during experiments Data analysis = Organize data in tables and graphs, look for patterns, and compare results with other scientists' data</p> Signup and view all the answers

<p>Variables = Factors in the experiment that change and affect the data Quantitative data = Measurable data such as length, time, or number of people Hypothesis = Prediction about how the independent variable will affect the dependent variable Engineering design = Using scientific knowledge to develop objects, tools, processes, and systems</p> Signup and view all the answers

<p>Models = Created to explain findings and describe how data can be used to design solutions to problems Testing = Conducting trials to improve designs using collected data Constants = Factors that must be kept constant to ensure they don’t accidentally affect the results Conclusion development = Developing conclusions and arguments based on evidence from investigations</p> Signup and view all the answers
