Define Biology
Science that deals with the study of life
2
Define Science
A process used to solve problems or develop an understanding of repetitive natural events that involves the accumulation of knowledge and the testing of the possible answers
3
A way of gaining information about the world by forming possible answers to questions, followed by rigorous testing to determine if the proposed explanations are supported by the facts
Scientific Method
4
What are the basic assumptions of science?
-There are specific causes for naturally reoccurring events
-The causes for events can be identified
-General rules can be used to describe nature
-A repeatable event probably have the same cause
-Observable by many
-Same fundamental rules of nature apply regardless of when or where

13
What is validity?
Able to be justified; on target
14
Explain what an experiment is
a recreation of an experiment that allows a scientist to prove or disprove a hypothesis
15
Many separate factors are
Variables
16

17
A _____ group is a group in which there is no manipulation of the variable
CONTROL group
18
An Experimental group is defined as?
A group in which a variable is manipulated
19
_______ variable is expected to change as a direct result of the manipulation of the independent variable
Dependent Variable

Independent variable is
The variable that is manipulated
21
Another word for reliable

22
What is inductive reasoning?
Process of developing general principles from the examination of many sets of specific facts
23
Deductive reasoning is?
The process of using general principles to predict the specific facts of a situation
24
Define scientific theory
Widely accepted, plausible, general statement about fundamental concepts in science that explain why things happen
25
A uniform or constant fact of nature that describes what happens in nature
Scientific law
26
What is the difference between scientific law and theories
Scientific laws describes what happens and theories describe why things happen
27
A deceptive practice that uses the appearance or language of science to convince confuse or mislead people into thinking something has scientific validity
