Nature of Science vo
Question | Answer |
---|---|
Science | A way of learning about the Natural world. Often involves the "relentless" testing and retesting of conclusions |
Hypothesis | A possible (and testable) explanation to a scientific question. Has low predictive value. Often expressed as an "if-then" statement |
Theory | A well-tested explanation to a scientific question. Has high predictive value |
Law | A very well tested explanation to a scientific question. Has very high predicitive value, and describes what scientists expect to happen every time |
Observation | the process of using one or more of the five senses to gather information about the world. |
Inference | an interpretation of an observation based on evidence and prior knowledge. |
Research | finding out what others have already learned about your scientidic questions. |
Variables | the factors that can change during an experiment. |
Independent Variable | the factor that the scientist changes during an experiment. Also called the manipulated variable. |
Dependent Variable | the factor that changes as a result of changes to the manipulated variable in an experiment. Also called the responding variable. |
Controlled Variable | the factors that you want to reamain constant (unchanged) during an experiment. |
Data | the observations and measurements you make during an experiment. |
Conclusion | a statement that sums up what you learned during an experiment. |
Bar Graph | a good way to display data when your manipulated (independent) variable is distinct (that is there are no other points between the ones you tested.) |
Dry Mix | an acronym for remebering which variables are graphed onto which axes. (Dependent, responding on Y and manipulated, independent on X) |
