Hypothesis

Definition

 

-tentative explination of how somthing works

Term

 

 

Prediction

Definition

 

is what should happen in a given situation if your hypothesis is correct.

Term

 

 

Theory

Definition
is an underlying principle of science that are substaniated by many different lines of evidence and have never been proven false through repeated sets of prediction and experimentation.
Term

 

 

Variable

Definition
is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.
Term

 

 

Independant Variable

Definition

 

is the variable that is changed by the scientist. To insure a fair test, a good experiment has only one independent variable.

Term

 

 

Dependent Variable

Definition

 

 

is the factor that is measured or counted.

Term

 

 

Experimental Group

Definition

 

 

has an altered variable under study

Term

 

 

Control Group

Definition

 

 

is the group under study where the variable is not altered

Term

 

 

Controlled (standardized) Variable

Definition

 


are factors that you try to keep the same between experimental groups

Term

 

 

Repitition

Definition

 

 

obtaining the same results after sveral different experiments. This helps to solidify the correctness of the hypothesis.

Term

 

 

Sampling Error

Definition

 

happens when you collect data from only one part of a population because you only have a sample of the true value of whatever you are measuring.

Term

 

 

The Scientific Method

Definition

 

involves the systematic accumlation of knowledge that is based on things that can be directly or indirectly experienced.
