| Term | Defintion |
|---|---|
| Science | an organized way of gathering and analyzing evidence about the natural world. |
| The Scientific Method | used to document scientific events and involves observing and asking questions, making inferences and forming hypotheses, conducting controlled experiments, collecting and analyzing data, and drawing conclusions. |
| Observations | the act of noticing and describing events or processes in a careful, orderly way. |
| Question | to narrow the focus of the inquiry, to identify the problem in specific terms and must be clear, concise, and easily testable. |
| Inference | a logical interpretation based on what scientists already know. |
| Hypothesis | a scientific explanation for a set of observations that can be tested in ways that support or reject it. |
| Variables | factors that can change throughout an experiment like temperature, light, time, and availability of nutrients. |
| Controlled Experiment | a situation in which one variable is changed and the others are kept unchanged. |
| Independent Variable | a variable that is deliberately changed in an experiment. |
| Dependent Variable | a variable or variables that are observed and that change in response to the manipulated variable. |
| Control Group | exposed to the same conditions as the experimental group except for one independent variable/ allows scientists to compare the test results against a baseline measurement to get a better understanding of what the true results from the experiment were. |
| Experimental Group | the group in an experiment that receives the variable being tested. |
| Data | detailed records of experimental observations. |
| Quantitative Data | numbers obtained by counting or measuring |
| Qualitative Data | descriptive and involve characteristics that cannot usually be counted. |
| Scientific Literature Article | the name for the type of document that scientists compile all of their data into. |
| Peer Review | the process by which scientific papers are reviewed by anonymous, independent experts. |
| Evidence | the information upon which inferences are based and consists of a collected body of data from observations and experiments. |
| Scientific Theory | a well-tested explanation that makes sense of a great variety of scientific observations and hypotheses and enables scientists to make accurate predictions about new situations. |
| Scientific Law | a statement that describes an observable occurence in nature that appears to always be true. |
| Bias | a paricular preference or point of view that is personal, rather than scientific. |
