<p>Hypothesis</p> Signup and view all the answers

<p>Ask a question = First, scientists ask a testable question based on their observations. Do research = Scientists research to learn about the topic they’re investigating. Form a hypothesis = Scientists form a hypothesis, or an educated guess, about what they think will happen based on the patterns they’ve seen. Perform an experiment = Scientists design and conduct an investigation to test the hypothesis. This usually involves changing one variable to see how it affects another.</p> Signup and view all the answers

<p>Asking a question = To initiate inquiry and form the basis for investigation. Researching = To acquire knowledge about the topic being investigated. Forming a hypothesis = To make an educated guess about the expected outcome of an experiment. Conducting an experiment = To test the validity of the hypothesis and observe cause-and-effect relationships.</p> Signup and view all the answers

<p>Tools for collecting data = Used by scientists to collect data that will help answer their question. Trials in an experiment = Involves multiple attempts to observe consistent results. Changing variables = Involves altering one factor to observe its impact on another. Patterns and hypotheses = Utilized to form an educated guess about expected outcomes.</p> Signup and view all the answers

<p>Problem-solving and creation = Applying scientific knowledge to solve problems or create new things through engineering design. Scientific knowledge improvement = Enhancing scientific understanding through research and experimentation. Testing hypotheses = Conducting investigations to verify educated guesses about cause-and-effect relationships. Observing patterns = Identifying recurring traits or behaviors in data to form hypotheses.</p> Signup and view all the answers

<p>Improving scientific knowledge = Enhancing understanding through learning and experimentation. Applying knowledge to solve problems = Using scientific insights to address challenges or develop innovative solutions. Collecting and analyzing data = Gathering information and scrutinizing it to draw conclusions or support arguments. Asking testable questions = Initiating inquiry by framing questions based on observations.</p> Signup and view all the answers

<p>Variables = Factors in the experiment that change 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</p> Signup and view all the answers

<p>Collecting and analyzing data = Scientists can collect qualitative or quantitative data during the experiment Draw a conclusion = Scientists use the data to form conclusions and support arguments about the problem they studied Share the results = Scientists share the results and conclusions with others Developing conclusions and arguments = Finally, scientists develop conclusions and arguments, based on evidence from their investigations</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 Hypothesis = A prediction about how the independent variable will affect the dependent variable Scientific method = A series of steps followed by scientists to answer questions or solve problems</p> Signup and view all the answers

<p>Models and representations = Scientists may create models, or representations, to describe their findings Engineering design = Engineers use scientific knowledge to solve problems by developing objects, tools, processes, and systems Data analysis = After an experiment, scientists develop conclusions and arguments based on evidence from their investigations Testing and improving designs = Engineers test what they design and use their data to improve their designs</p> Signup and view all the answers

<p>Data organization = Scientists often organize the data in tables and graphs after collecting it Comparison of results = Scientists compare their results with other scientists' data to look for similarities and differences Prediction making = When the experimenter forms a hypothesis, they are making a prediction about how the independent variable will affect the dependent variable Sharing findings = Scientists share the results and conclusions with others after completing an experiment</p> Signup and view all the answers
