Bacterial Myths (Microbiology)

One of the most important ideas in designing and interpreting results is experimental control.

 experimental control:

       Stating known conditional variations to determine their effects on the experiment.  The word control is used because the scientist is able to adjust  these variables.  They do not include unknown variable or those in the experiment which can not be controlled.  Experimental controls are used intentionally.  They are useful in evaluating the procedure and there effects.  It is a common belief that the differences between things should drive variations in results. i.e. differences cause differences

4-can create a procedure to introduce an experiment control and state the reason for its implementation
3- can identify in a procedure experimental control and state the rational
2-can describe discuss define and experimental control from other experimental design elements
1- can identify an experimental control given various design elements
