Scientific inquiry is the diverse ways in which scientists study the natural world and propose explanations based on collected evidence. (NSTA) STEPS FOR CONDUCTING SCIENTIFIC INQUIRY1. Identify a problem or ask a question2. Research the problem or question3. Form a possible hypothesis4. Design and conduct a controlled experiment5. Collect and analyze the results of the experiment6. Draw conclusions7. Communicate the results Controlled Experiment - experiment in which only one variable or condition is changed; all other variables are held constant Control Group - part of the experiment that is run under normal conditions or doesn't receive the experimental treatment; serves as reference for other groups Experimental Group - part of the experiment in which the scientist deliberately changes on variable/conditon Variables - any factor or condition in an experiment that changes or can be changed Independent Variable (I.V.) - variable that is purposely changed by the scientist ["I" the scientist purposely change the Independent variable]; what is being tested Dependent Variable (D.V.) - variable that is being observed or measured during the experiment; the data that is being collected; changes because of the I.V.
Observations - process of gathering information in careful, orderly manner Data - information gathered or measured
Quantitative Observations or Data - numerical information or data counted or measured
Qualitative Observations or Data - descriptions that involve characteristics that cannot be counted or measured
Hypothesis - scientific explanation for observations/measurements; must be testable; often written as an if-then statement form - If this is done (I.V.) then this (D.V.) will happen. Scientific Theory - explanation that is supported by the data and observations that many scientists have made

Control Group - part of the experiment that is run under normal conditions or doesn't receive the experimental treatment; serves as reference for other groups
Experimental Group - part of the experiment in which the scientist deliberately changes on variable/conditon
Variables - any factor or condition in an experiment that changes or can be changed
Independent Variable (I.V.) - variable that is purposely changed by the scientist ["I" the scientist purposely change the Independent variable]; what is being tested
Dependent Variable (D.V.) - variable that is being observed or measured during the experiment; the data that is being collected; changes because of the I.V.
