scientific process, characteristics of life

TermDefinition
Adaptation Inherited characteristic of a species that develops over time in response to an environmental factor
Biology Science of life
Constant A factor that remains fixed during an experiment while the independent and dependent variables change; controlled variable
Control group In a controlled experiment, the group not receiving the factor being tested; the standard to compare to.
Data Quantitative or qualitative information gained from scientific investigation.
Dependent variable Factor being measured in a controlled experiment; its value changes because of the changes to the Independent variable.
Development Changes an organism undergoes in its lifetime before reaching its adult form; characteristic of life
Experiment Procedure performed in a controlled setting to test a hypothesis and collect precise data.
Experimental group In a controlled experiment, the group receiving the factor being tested.
Growth Process that results in mass being added to an organism; characteristic of life
Homeostasis Regulation of an organism's internal environment to maintain conditions needed for life (temperature, pH, blood glucose)
Hypothesis Testable explanation of a situation.
Independent variable The one factor that can be changed in a controlled experiment; is the factor tested and affects the experimental outcome.
Inference Assumption based on observations
Metric system Measurement system whose divisions are powers of ten.
Observation Orderly, direct information gathered about a phenomenon. Something you can directly see, taste, hear, touch etc.
Organism Anything that has or once had all the characteristics of life

Peer Review A process in which the procedures used during an experiment may be repeated and the results evaluated by scientists who are in the same field.
Pseudoscience a claim, belief or practice presented as scientific, but which does not adhere to the scientific method.
Reproduction Production of offspring; characteristic of life
Response Organism's reaction to a stimulus
Science A body of knowledge based on the study of nature
Scientific Method A series of problem-solving procedures that might include observations, forming a hypothesis, experimenting, analyzing data and drawing conclusions.
SI System of measurements used by scientists, abbreviation of the International System of Units.
Species Group of organisms that can interbreed and produce fertile offspring
Stimulus Any change in an organism's internal or external environment that causes the organism to react.
Theory Explanation of a natural phenomenon based on many observations and investigations over time.
