If you want multiple pictures of something, try models (see definition of theory and model, below). Models can be essentially throw-away thought experiments; you can say If A, then B, then C, then D and test for D. If D is found, that supports the model and maybe it's worth more effort. Who knows, it might grow up to be a theory some day!
There is no limit to the number of models which can be used; they can range from ridiculously simple to more complex. Think of them as tools for exploration, while a theory is more of a well-tested and robust explanation.
Definitions (from a google search):
Theory: a well-substantiated explanation of some aspect of the natural world; an organized system of accepted knowledge that applies in a variety of circumstances to explain a specific set of phenomena; "theories can incorporate facts and laws and tested hypotheses." Addendum: "Theories do not grow up to be laws. Theories explain laws." (Courtesy of VadeRetro.)
Model: a simplified framework designed to illuminate complex processes; a hypothetical description of a complex entity or process; a physical or mathematical representation of a process that can be used to predict some aspect of the process
"Who knows, it might grow up to be a theory some day!"
In that case, one is modelling a test for a hypothesis. The model won't beocme theory, the hypothesis will. In general, models are based on both theory and law.
