Science is a process by which we try to understand how the natural and physical world works and how it came to be that way.
Objective= Not influenced by feelings, interests and prejudices; UNBIASED
Subjective = Influenced by feelings, interests and prejudices; BIASED
Anything done scientifically can be relied upon to be accurate and reliable.
Knowledge of what science is, what it can and cannot do, and how it works, is important for all people.
Objectivity is the key to good science.
To be objective, experiments need to be designed and conducted in a way that does not introduce bias into the study.
OBSERVATION—act of gathering information firsthand using your five senses
Be careful not to confuse an observation with an inference
HYPOTHESIS—proposed, testable explanation for the way “something” functions. The “educated guess”
When scientists look at DATA they…
THEORY—highly tested, generally accepted principal that explains a vast number of observations and experimental data
Good science depends on a well-designed experiment that minimizes bias by using the appropriate:
