Scientific Method

Scientific Method the procedure scientists use to help explain why things happen the way they do
Problem something you don't understand but you can do an experiment to help you understand
Scientific problems usually based on observation of scientific phenomena; the first step of the scientific method involves being able to recognize the problem
Observations consists of receiving knowledge of the outside world through our senses, or recording information using scientific tools and instruments
Inference an idea or conclusion that's drawn from evidence and reasoning. An inference is an educated guess; conclusion about our observations
Hypothesis a testable explanation for the details you observed
Experiment tests the hypothesis
Variable something that changes in an experiment
Data record of the observations that is analyzed in order to make a conclusion
Conclusion an experiment that is repeated several times, in order to rule out accidents and any variables that may not have been considered
Theory explanatory statement that’s been repeatedly confirmed through experimental testing
Scientific knowledge if a theory is proven valid over and over again
Control Group The group or subject that is used as a standard for comparison in an experiment.
Experimental Group The group or subjects that is included in the experiment. This is the group where the independent variable is applied.
Measure To compare the characteristics of something (such as mass, length, volume) with a standard (such as grams, meters, liters).
Prediction A statement made about the future outcome of an experiment based on past experiences or observations. It is found in the "then" portion of a hypothesis.
Qualitative data Data that is based on observable characteristics of things or events that can be collected using the five senses. Example: "The juice tastes sweet to me."
Quantitative data Data that is based on measurable characteristics of things or events such as mass, volume, length, and quantity. Example: "There is one liter of juice in the carton.
Independent Variable A factor that can be changed or manipulated in an experiment by the scientist; "you change it" variables.
Dependent Variable A factor that responds to changes in other variables in an experiment; "it changed" variables.
Constant or controlled Variable A variable variables that are held the same or constant for all experimental groups.
