- Front
- Back
Science |
-involves objective, logical, and repeatable attempts to understand the principles and forces working in the natural universe |
|
Scientific Skepticism |
-Also referred to as skeptical inquiry, questions claims based on their scientific verifiability rather than accepting claims based on faith -Uses critical thinking to analyze such claims and opposes claims which lack scientific evidence. |
|
Deduction |
-involves determining a single fact from a general statement; it is only as accurate as the statement |
|
Induction |
-involves determining a general statement that is very likely to be true, from several facts. |
|
Scientific Methods |
-the process of scientific investigation -based on gathering observable, empirical (produced by experiment or observation), and measurable evidence that is critically evaluated. |
|
Hypothesis |
-A suggested explanation based on evidence that can be tested by observation or experimentation. |
|
Observation |
-The act of noting or detecting phenomenon by the senses. For example, taking measurements is a form of observation. |
|
Experiment |
-a test that is used to eliminate one or more of the possible hypotheses until one hypothesis remains |
|
Controls |
-subjects that are not tested during the investigation |
|
Variable |
-a factor that can change over the course of an experiment |
|
Independent Variable |
-factors whose values are controlled by the experimenter |
|
Dependent Variable |
-change in response to the independent variable |
|
Constants (Controlled Variables) |
- variables that are kept constant to prevent them from influencing the effect of the independent variable on the dependent variable |
|
Accuracy |
- the measure of how close a calculated or measured quantity is to its actual value |
|
Precision |
-reproducibility or repeatability |
|
Error |
-a boundary on the precision and accuracy of the result of a measurement |
|
Scientific Theories |
-hypotheses which have stood up to repeated attempts at falsification and are thus supported by a great deal of data and evidence |
|
Theory |
-guess or an opinion |
|
Scientific Laws |
-similar to scientific theories in that they are principles which can be used to predict the behavior of the natural world -typically well-supported by observations and/or experimental evidence -usually refers to rules for how nature will behave under certain conditions |
|
Scientific Journals |
-communicate and document the results of research carried out in universities and various other research institutions |
|
Peer Review |
-peers review your work to ensure that articles meet the journal's standards of quality, and scientific validity |
|
Bias |
-a position for favoring one particular point of view over another, and it is usually based on preconceived ideas about a situation |
|
Ethics |
-also called moral philosophy, is the discipline concerned with what is morally good and bad, right and wrong |
|
Biotechnology |
-technology based on biology; it involves the use of organisms or biological processes and can be especially used in agriculture, food science, and medicine |
|
Bioremediation |
-The use of microorganisms to clean up contaminated sites such as an oil spill |
|
Simulation |
-A model that runs over time; brings a model to life and shows how a particular object or phenomenon will behave |
