Science

an organized way of gathering and analyzing evidence about the natural world -way of observing, a way of thinking, and a way of knowing about the world

Data

evidence; information gathered from observations

Controlled Experiment

experiment when only one variable is changed

What procedures are at the core of methodology?

involves... -observing and asking questions -making inference and forming hypotheses -conducting controlled experiments -collecting and analyzing data -drawing conclusions

Control Group

is exposed to the same conditions as the experimental group except for one independent variable

What are the goals of science?

is to provide natural explanations for events in the natural world. Science also aims to use those explanations to understand patterns in nature and to make useful predictions about natural events.
