Question | Answer |
---|---|
Experimental | "SCIENTIFIC METHOD" Scientists make most of their discoveries using the _____________ method. |
Identfy, answer questions | "SCIENTIFIC METHOD" This method consists of a series of steps that scientists worldwide use to _________ and _________ _____________. |
hypothesis | "SCIENTIFIC METHOD" A __________ is a theory or explanation that is based on obervation and that can be tested. |
predictions | "SCIENTIFIC METHOD" ___________ are statements made in advance that express the results that will be obtained from testing a hypothesis if the hypothesis if the hypothesis is supported. |
experiments | "SCIENTIFIC METHOD" ___________- are procedures that are carried out under controlled conditions to discover, demonstrate, or test a fact, theory, or general truth. |
cause-and-effect | "SCIENTIFIC METHOD" Experiments should be designed to pinpoint ______-- ______-- ______ relationships. |
variable | "SCIENTIFIC METHOD" The ______ is the factor that changes in an experiment in order to test a hypothesis. |
two | "SCIENTIFIC METHOD" To test for one variable, scientists usually study two groups or situations at one time, with the variable being the only difference between the ___ groups. |
experimental | "SCIENTIFIC METHOD" The ____________ group is the group in the experimental that is identical to the control group except for one factor and is compared with controls group. |
control | "SCIENTIFIC METHOD" The _________ group is the group in the experimental that serves as a standards of comparison with another group to which the control to which the control group is identical execpt for one factor. |
Data | "SCIENTIFIC METHOD" ______ is any pieces of information acquired through oberservation or experimentation. |
graphing | "SCIENTIFIC METHOD" _________ the information makes the trends presented in tables easier to see. |
analyzing | "SCIENTIFIC METHOD" Scientists determine the results of their experiment by __________their data and comparing the outcome of their experiments with their predictions |
reliability | "SCIENTIFIC METHOD" The more often an experiment with the same results, in different places and by different people, the more sure scientists become about the____________ of their conclusions |
often repeat | "SCIENTIFIC METHOD" Scientists_______ ________ repeat their results, sometimes in scientific article, to share what they have learned with other scientists |
articles | "SCIENTIFIC METHOD" Scientific__________ include the question the scientists explored, the reasons why the question is important, background information, a precise description of how the work was done, the data collected, and the scientist's interpretation of the data. |
correlation | CORRELATION METHOD ___________________- is the linear dependence between two vriables. between two variables |
eliminate | CORRELATION METHOD Scientists become more sure about their conclusions only if they find the same correlation in different places as they continue to __________ other possible explanations |
